AB  - Triticale (Triticosecale Wittmack) is a cereal crop species developed to combine positive traits of wheat and rye into a single plant (Arendt and Zannini 2013). Due to its high protein content, favorable amino acid composition, and nutritional values higher than maize, triticale is an excellent component for preparing feed for domestic animals (Đekić et al. 2019). In May 2017, discolored spikes of triticale were observed in a field in Zemun Polje, Serbia, with a disease incidence between 15 and 20%. In total, 400 kernels obtained from discolored spikes were surface sterilized with 1% sodium hypochlorite solution for 3 min, then rinsed three times with sterilized water, plated on potato dextrose agar (PDA) at 25°C, and incubated in the dark for 7 days. In total, 15 isolates of genus Fusarium on PDA formed cottony white to greyish-purple colonies with dark yellow to purple-gray reverse and average colonies. Obtained isolates were transferred to carnation leaf agar (CLA) and synthetic nutrition agar (SNA) for a 7-day incubation in the dark at 25°C. Ten isolates formed “rabbit ear” monophialides, which is the main characteristic of Fusarium verticillioides (Sacc.) Nirenberg. Microconidia are formed from monophialids in long chains. Their shape is oval with a flattened base, without septa (4.0 to 18.0 by 1.5 to 4.5 µm). The shape of macroconidia is slightly falcate to almost straight (3.5 to 4.5 by 31 to 58 µm). Chlamydospores are not produced (Leslie and Summerell 2006). The genomic DNA from one F. verticillioides isolate was extracted using the DNeasy Plant Mini kit (Qiagen, Hilden, Germany) according to the manufacturer’s protocol. Molecular identification was confirmed by sequencing the internal transcribed spacer (ITS), translation elongation factor 1α (EF-1α), and RPB2 (O’Donnell et al. 2000). The sequence was deposited in GenBank as MZ664391, MZ666958, and MZ666957. This sequence was compared with the sequences of F. verticillioides strains registered in the GenBank database based on nucleotide similarity. It showed 100% identity to the sequences MT180471.1 (ITS), MN861767.1 (EF-1α), and MT264836.1 (RPB2). Pathogenicity of all isolates was tested on 20 randomly selected triticale spikes in four replicates (Mesterházy et al. 1999). Inoculation was performed when half of the plants reached the flowering stage by spraying with 20 ml of spore suspension (1 × 106 spores/ml from 7-day-old cultures on PDA). F. verticillioides RBG 1603 Q27 was used as a positive control. Inoculated spikes were covered with PVC bags for 48 h. Discolored spikes were observed after 3 weeks of incubation in a greenhouse at 20°C with a photoperiod of 16 and 8 h (light and dark). All inoculated spikes showed symptoms, similar to those from field infections. Control spikes were symptomless. The fungus was reisolated and was morphologically identical to the original isolates, thus completing Koch’s postulates. Based on morphological, molecular, and pathogenic features, the isolated fungus was identified as F. verticillioides. Fusarium spp. infect crop plants worldwide, resulting in yield loss and reduced grain quality due to mycotoxin contamination (Asam et al. 2017). In Serbia, F. verticillioides was isolated from wheat and barley grains (Stanković et al. 2012) and, to the best of our knowledge, this is the first report of F. verticillioides on triticale grain in Serbia.

AB  - Cereal seeds safety may be compromised by the presence of toxic contaminants, such as aflatoxins.
Besides being carcinogenic, they have other adverse health effects on humans and animals. In
this preliminary study, we used two non‑invasive optical techniques, optical fiber fluorescence
spectroscopy and multispectral imaging (MSI), for discrimination of maize seeds naturally
contaminated with aflatoxin B 1 (AFB 1 ) from the uncontaminated seeds. The AFB 1‑contaminated
seeds exhibited a red shift of the emission maximum position compared to the control samples.
Using linear discrimination analysis to analyse fluorescence data, classification accuracy of 100%
was obtained to discriminate uncontaminated and AFB 1‑contaminated seeds. The MSI analysis
combined with a normalized canonical discriminant analysis, provided spectral and spatial patterns
of the analysed seeds. The AFB 1‑contaminated seeds showed a 7.9 to 9.6‑fold increase in the seed
reflectance in the VIS region, and 10.4 and 12.2‑fold increase in the NIR spectral region, compared
with the uncontaminated seeds. Thus the MSI method classified successfully contaminated from
uncontaminated seeds with high accuracy. The results may have an impact on development of
spectroscopic non‑invasive methods for detection of AFs presence in seeds, providing valuable
information for the assessment of seed adulteration in the field of food forensics and food safety.

AB  - In Serbia, aspergillus ear rot caused by the disease pathogen Aspergillus parasiticus
(A. parasiticus) was first detected in 2012 under both field and storage conditions. Global climate
shifts, primarily warming, favour the contamination of maize with aflatoxins in temperate climates,
including Serbia. A five-year study (2012–2016) comprising of 46 A. parasiticus strains isolated from
maize kernels was performed to observe the morphological, molecular, pathogenic, and toxigenic
traits of this pathogen. The HPLC method was applied to evaluate mycotoxin concentrations in this
causal agent. The A. parasiticus isolates synthesised mainly aflatoxin AFB1 (84.78%). The percentage
of isolates synthesising aflatoxin AFG1 (15.22%) was considerably lower. Furthermore, the concen-
tration of AFG1 was higher than that of AFB1 in eight isolates. The polyphase approach, used to
characterise isolates, showed that they were A. parasiticus species. This identification was verified by
the multiplex RLFP-PCR detection method with the use of restriction enzymes. These results form an
excellent baseline for further studies with the aim of application in the production, processing, and
storage of cereal grains and seeds, and in technological processes to ensure the safe production of
food and feed.

AB  - The objective of the present study was to investigate the susceptibility of maize hybrids to the
natural mycotoxins contamination: aflatoxin total (AFLA), deoxynivalenol (DON),
zearalenon (ZEA) and fumonisins (FB). Hybrids were grown during two production years
(2019 and 2020) in two locations. Mycotoxin contamination of maize grains was evaluated in
five sweet maize hybrids. Contamination level of investigated hybrids of first cluster was
mainly by below average values of ZEA (all equal to zero) and DON. Hybrids PK4 (S) 2020,
PK6 (MS) 2020 and PK4 (MS) 2020 had below average values for AFLA, while remaining
treatments of this cluster have mostly elevated values of this mycotoxin. Contamination level
of investigated hybrids of second cluster mostly had increased values of mycotoxins ZEA
and DON and below average values of AFLA. Samples did not contain fumonisins.
Mycotoxin contamination were significantly affected by hybrids and years. We have
established that DON and ZEA levels were influenced by the environmental conditions.
There were no significant effects of location on the level of AFLA in the sweet maize
hybrids. The variation in the properties of mycotoxin content (DON) was significantly
influenced by hybrids, and there was no significance of hybrids x location interaction.
Differences were more expressed for the content of ZEA and AFLA compared to the content
of DON. Hybrid PK1 had the lowest content of DON, while it had the highest content of
ZEA. Mycotoxin analyses showed that in all tested hybrids, levels of AFLA, DON, ZEA and
FBs were below the maximum permissible levels stipulated by the legislation of the
European Union and the Republic of Serbia in maize intended for direct human consumption.
These results confirmed that the susceptibility of hybrids is one of the important risks, in addition to climatic factors, for the appearance of toxigenic fungi and their mycotoxins.
Genotype tolerance is very important as a preventive measure, which indicates that breeders
have to pay attention to it in sweet maize breeding programs.

više od prosečnih vrednosti za ostale tretmane ovog klastera. Nivoi kontaminacije proučavanih

hibiridi i godine. Utvrđeno je da su uslovi sredine uticali na nivoe DON i ZEA. Lokacija nije
značajno uticala na nivo AFLA kod hibrida kukuruza šećerca. Hibridi su značajno uticali na
variranje sadržaja mikotoksina (DON), dok hibrid × lokacija interakcija nije bila značajna.

utvrđen je kod hibrida PK1, kod koga je sadržaj ZEA bio najviši. Analize mikotoksina pokazuju
da su nivoi AFLA, DON, ZEA i FB u svim ispitivanim hibridima bili ispod maksimalno
dozvoljenih nivoa koji su propisani zankonima Evropske Unije i Republike Srbije za kukuruz

AB  - During the 2014-2017 period, wheat samples were collected from discoloured spikes affected by Fusarium head blight (FHB) from 20 locations in Serbia. After isolation, fungi were cultivated on potato dextrose agar (PDA) at 25oC for 7 days. Based on the in situ identification on PDA, 36 isolates of the section Liseola were selected for further analyses. The pathogenicity of all isolates was confirmed on wheat leaves. The virulence of isolates was determined by measuring the lengths of spots formed at the inoculation leaf site. In order to prove the presence of the species Fusarium verticillioides, a pair of primers FV-F2/FV-R was used. This pair of primers amplifies the sequence of the gaoB gene, and it proved to be specific for the stated species. Moreover, for the same purpose, a pair of primers VER1-VER2 based on the calmodulin partial gene was used. The reference isolate RBG 1603 Q27 was used as a positive control. The pair of primers VER1-VER2 produced a band of the expected size - 578 bp in 18 isolates, while using FV-F2/FV-R, a 370bp long band confirmed the presence of F. verticillioides in 16 samples. Sixteen out of 18 isolates verified with VER1-VER2 were also identified as F. verticillioides with FV-FS/FV-R. No amplification was observed in a negative control.

AB  - Barley (Hordeum vulgare L.) is a secondary grain crop in Serbia used commercially for animal feed, seed, and human food applications. The production of barley in the 2016 to 2017 growing season reached a record yield of almost 400,000 metric tons (USDA 2017). Aspergillus contamination has been rare in the agroecological conditions of cereal-growing areas in Serbia. Changes in climatic factors, such as occurrence of high temperatures and prolonged droughts, increased frequency of Aspergillus spp. Species Aspergillus parasiticus was isolated from maize grain for the first time in Serbia in 2012 and from wheat grains in 2017 (Nikolic et al. 2018). We hypothesized that these pathogens can also be present in barley fields in Serbia. Barley spikes exhibiting bleaching were sampled at the beginning of June 2017 grown in northern Serbia. In severe infections, barley spikes get a dry look with awns that stand upright and firm. The incidence of the disease of the bleached spiked in the field was 15 to 20%. From each representative sample, 100 shriveled grains were collected. After surface sterilization with bleach/distilled water 1:3, 100 grains per sample (10 per Petri dish) were placed on potato dextrose agar and incubated at 25°C for 7 days. After isolation, 50% of isolates were identified as Alternaria spp., 20% as Fusarium spp., approximately 15% as Aspergillus spp. In order to reliably identify individual species of fungi, the fragments of colonies were transferred to malt extract agar (MEA) and Czapek yeast agar (CYA) and incubated in the dark for 7 days. The fungal colonies were dark green. The reverse side was pale yellow. The average colony diameter was 65 mm. Conidia were spherical and rough with thick walls. The average size of conidia was 5.1 µm. Colonies were floccose and thin on MEA and CYA. Based on growth and morphological characteristics, isolates were determined as A. parasiticus (Pitt and Hocking 2009). Molecular detection of Aspergillus species was done by using PCR-restriction fragment length polymorphism analysis of the aflR-aflJ (genes for aflatoxin biosynthesis) intergenic spacer. The restriction enzyme BglII was able to cut the PCR product of A. parasiticus at one restriction site, resulting in two fragments of 363 and 311 bp (El Khoury et al. 2011). A. parasiticus CBS 100926 was used as a reference isolate. The pathogenicity of 20 isolates was verified on a group of 20 randomly selected spikes in four replicates (Mesterházy et al. 1999). A 7-day-old culture of each isolate was used for the preparation of the spore suspension (1 × 10⁶ spores/ml). Inoculation was carried out after 50% of plants reached the anthesis stage. Groups of 20 selected spikes were sprayed from all sides with 20 ml of fungal spore suspension. Control spikes were inoculated by applying an equal amount of sterile distilled water. The infection rate was estimated after 3 weeks on a 1 to 7 scale, with 1 = 0 to 5%, 2 = 5 to 15%, 3 = 15 to 30%, 4 = 30 to 50%, 5 = 50 to 75%, 6 = 75 to 90%, and 7 = 90 to 100% infected spike area. The average infection rate was 3.2. The pathogen was reisolated from the inoculated spikes and identified as A. parasiticus, with the aim to confirm Koch’s postulates. Developed symptoms were similar to those observed on spikes collected from the field. Control spikes did not show any symptoms of the disease. These results confirmed the pathogenicity of A. parasiticus on H. vulgare. To the best of our knowledge, this is the first report of the occurrence of A. parasiticus on barley grain in Serbia. Because A. parasiticus is known to be a severe aflatoxin producer and climatic changes can increase the frequency of this fungus, further studies are necessary to improve strategies for food safety and quality.

We hypothesized that these pathogens can also be present in barley fields in Serbia. Barley spikes exhibiting bleaching were sampled at the beginning of June 2017 grown in northern Serbia. In severe infections, barley spikes get a dry look with awns that stand upright and firm. The incidence of the disease of the bleached spiked in the field was 15 to 20%. From each representative sample, 100 shriveled grains were collected. After surface sterilization with bleach/distilled water 1:3, 100 grains per sample (10 per Petri dish) were placed on potato dextrose agar and incubated at 25°C for 7 days. After isolation, 50% of isolates were identified as Alternaria spp., 20% as Fusarium spp., approximately 15% as Aspergillus spp. In order to reliably identify individual species of fungi, the fragments of colonies were transferred to malt extract agar (MEA) and Czapek yeast agar (CYA) and incubated in the dark for 7 days. The fungal colonies were dark green. The reverse side was pale yellow. The average colony diameter was 65 mm. Conidia were spherical and rough with thick walls. The average size of conidia was 5.1 µm. Colonies were floccose and thin on MEA and CYA. Based on growth and morphological characteristics, isolates were determined as A. parasiticus (Pitt and Hocking 2009). Molecular detection of Aspergillus species was done by using PCR-restriction fragment length polymorphism analysis of the aflR-aflJ (genes for aflatoxin biosynthesis) intergenic spacer. The restriction enzyme BglII was able to cut the PCR product of A. parasiticus at one restriction site, resulting in two fragments of 363 and 311 bp (El Khoury et al. 2011). A. parasiticus CBS 100926 was used as a reference isolate. The pathogenicity of 20 isolates was verified on a group of 20 randomly selected spikes in four replicates (Mesterházy et al. 1999). A 7-day-old culture of each isolate was used for the preparation of the spore suspension (1 × 10⁶ spores/ml). Inoculation was carried out after 50% of plants reached the anthesis stage. Groups of 20 selected spikes were sprayed from all sides with 20 ml of fungal spore suspension. Control spikes were inoculated by applying an equal amount of sterile distilled water. The infection rate was estimated after 3 weeks on a 1 to 7 scale, with 1 = 0 to 5%, 2 = 5 to 15%, 3 = 15 to 30%, 4 = 30 to 50%, 5 = 50 to 75%, 6 = 75 to 90%, and 7 = 90 to 100% infected spike area. The average infection rate was 3.2. The pathogen was reisolated from the inoculated spikes and identified as A. parasiticus, with the aim to confirm Koch’s postulates. Developed symptoms were similar to those observed on spikes collected from the field. Control spikes did not show any symptoms of the disease. These results confirmed the pathogenicity of A. parasiticus on H. vulgare. To the best of our knowledge, this is the first report of the occurrence of A. parasiticus on barley grain in Serbia. Because A. parasiticus is known to be a severe aflatoxin producer and climatic changes can increase the frequency of this fungus, further studies are necessary to improve strategies for food safety and quality.",

AB  - Field trials were set up in the Belgrade area (Serbia) in 2013 and 2014 to determine the effect of plant density on the natural incidence of potentially toxigenic fungi and the level of mycotoxins, aflatoxin B-1 (AFB(1)), deoxynivalenol (DON) and fumonisins (FBs) in two Serbian maize hybrids of the FAO maturity group 700 (ZP 735 and NS Zenit). Three plant density treatments, namely, 55,000 plants ha(-1) (PD1), 64,000 plants ha(-1) (PD2) and 75,000 plants ha(-1) (PD3), were evaluated. The incidence of identified potentially toxigenic fungi of the genera Aspergillus, Fusarium, and Penicillium and the FB level increased significantly (P  lt = 0.01) at PD3. The effect of year was also significant (P  lt = 0.01) on the incidence of toxigenic fungi, as all fungal species had a higher incidence in 2014 than in 2013, with the exception of Aspergillus spp. that showed a significantly higher incidence in 2013. Levels of all tested mycotoxins were higher in 2014 than in 2013. The higher incidence of Fusarium graminearum, Fusarium proliferatum, Fusarium subglutinans, Fusarium verticillioides and Penicillium spp. and higher levels of AFB1 and FBs were observed in the hybrid ZP 735, whereas the hybrid NS Zenit had a higher incidence of Aspergillus spp. The effect of hybrids was not significant on the incidence of F. subglutinans and the DON level. These results indicated that the highest investigated plant density increased the fungal incidence and the FB level, especially in 2014. Although the two hybrids originated from the same FAO group, they differed in their effects on some toxigenic fungi and mycotoxins.

AB  - In this study, a total of 30 poultry (chicken and laying hens) feed samples collected from different poultry farms in Serbia in 2016 were tested for fungal and aflatoxin contamination. Using the plate count and standard mycological methods, total fungal counts and potentially toxigenic fungal genera were determined. Natural occurrence of aflatoxin B1 (AFB1) was detected by ELISA (enzyme-linked immune sorbent assay) method. The total fungal count was in the range from 1 x 102 (2 log CFU g-1 ) to 1.83 x 105 CFU g-1 (5.26 logCFU g-1 ). The majority of the chicken feeds (78.57%) had the total fungal count in the ranged from 1 x 102 to 4.8 x 104 CFU g-1 , whereas in 68.75% of the laying hens feeds it was ranged from 5.3 x 104 to 1.83 x 105 CFU g -1 . In 21.43% of the chicken feeds fungal contamination reached the level above the regulation limits. Three potentially toxigenic fungal genera, Aspergillus, Fusarium, and Penicillium, have been identified. In the tested poultry feed samples, more samples contaminated with Aspergillus were determined compared to samples contaminated by Fusarium and Penicillium species. The AFB1 was detected in concentrations from 1.34 to 18.29 g kg-1 , with an average of 4.47 and 4.56 g kg-1 in the chicken and laying hens feed samples, respectively. In 14.29% of the chicken feeds, the level of AFB1 was above the regulation limits. The obtained results confirmed the importance of continuous mycological and mycotoxicological control of poultry feed, as well as need to improve risk assessments of such contaminants along the food chain.

Najveći broj uzoraka hrane za piliće (78,57%) imao je ukupan broj gljiva u rangu od 1 x 102 do 4,8 x 104 CFU g-1 , dok je 68,75% uzoraka hrane za nosilje imalo ukupan broj gljiva u rangu od 5,3 x 104 do 1,83 x 105 CFU g-1 . U 21,43% hrane za piliće ustanovljen je nedozvoljen ukupan broj gljiva. Identifikovana su tri potencijalno toksigena roda gljiva Aspergillus, Fusarium i Penicillium. Najveći broj ispitivanih uzoraka hrane za živinu bio je kontaminiran Aspergillus vrstama, u odnosu na Fusarium i Penicillium vrste koje su kontaminirale manji broj uzoraka.

U 14,29% uzoraka hrane za piliće ustanovljen je nedozvoljen sadržaj AFB1. Dobijeni rezultati potvrđuju značaj stalne mikološke i mikotoksikološke kontrole hrane za živinu, kao i potrebu za usavršavanjem procene rizika od štetnih (gljivičnih) kontaminenata u lancu ishrane.

AB  - The influence of climatic conditions on the levels of fumonisins in maize grown in Serbia was studied over eight years (2008 to 2015), investigating the possible relationship between the levels of fumonisins contamination in maize in relation to registered weather/climatic conditions. Presence of these mycotoxins in maize after harvest was evaluated based on climatic conditions within two periods: 10 days before and 10 days after 50% silking. Categories of fumonisins levels were transformed into classes. Chi-square test for association was used in analysing relationships between results of fumonisins levels and calendar years. Mann-Whitney U-test was used to compare differences between meteorological data of two subsets in years with high and low fumonisins level. There was a statistically significant association between the fumonisins levels and calendar years chi(2)=247.954; (P lt 0.05). This study identified low precipitation and low humidity combined with high solar radiation as a critical parameter combination for elevated levels of fumonisins. The statistically significant difference in relation to some of the examined parameters suggests that maize in Serbian agro-climatic conditions is more susceptible to fungal colonisation, and subsequent fumonisin production in the period of 10 days before 50% silking.

AB  - Agroecological and climatic conditions in Serbia greatly affected the development of toxigenic fungi and occurrence of mycotoxins in the maize. The presence of fungal toxigenic Aspergillus and Fusarium species and levels of aflatoxin B 1 (AFB 1) and sum of fumonisins B 1 , B 2 and B 3 (FBs) were established in 127 maize kernel samples harvested during 2012 (37 samples) and 2013 (90 samples). The periods of silking and grain filling of the maize in 2012 in comparison to 2013 were characterised with extremely dry spells, with high temperatures and low precipitation sums. The mean incidences of A. flavus and F. verticillioides were 50.4 and 11.7% in 2012 and 18.9 and 33.4% in 2013, respectively. According to the regulations of the World Health Organisation, unacceptable levels of AFB 1 (>20 μg kg-1) and FBs (>2000 μg kg-1) were established in the 30.6 and 24.1% samples of 2012 and 16.7 and 40% maize kernel samples of 2013, respectively. It can be concluded that high temperatures and low precipitation sums in 2012 favoured the development of A. flavus affecting the high level of AFB 1 , in comparison with F. verticillioides and the production of FBs. There was no positive correlation between the incidences of A. flavus and F. verticillioides, while a statistically significant positive correlation has been found between AFB 1 and FBs levels, in both investigated years (2012-2013). This indicates that the mycotoxin production depended more on weather conditions than on the distribution of corresponding toxigenic fungal species.

abstract = "Agroecological and climatic conditions in Serbia greatly affected the development of toxigenic fungi and occurrence of mycotoxins in the maize. The presence of fungal toxigenic Aspergillus and Fusarium species and levels of aflatoxin B 1 (AFB 1) and sum of fumonisins B 1 , B 2 and B 3 (FBs) were established in 127 maize kernel samples harvested during 2012 (37 samples) and 2013 (90 samples). The periods of silking and grain filling of the maize in 2012 in comparison to 2013 were characterised with extremely dry spells, with high temperatures and low precipitation sums. The mean incidences of A. flavus and F. verticillioides were 50.4 and 11.7% in 2012 and 18.9 and 33.4% in 2013, respectively. According to the regulations of the World Health Organisation, unacceptable levels of AFB 1 (>20 μg kg-1) and FBs (>2000 μg kg-1) were established in the 30.6 and 24.1% samples of 2012 and 16.7 and 40% maize kernel samples of 2013, respectively. It can be concluded that high temperatures and low precipitation sums in 2012 favoured the development of A. flavus affecting the high level of AFB 1 , in comparison with F. verticillioides and the production of FBs. There was no positive correlation between the incidences of A. flavus and F. verticillioides, while a statistically significant positive correlation has been found between AFB 1 and FBs levels, in both investigated years (2012-2013). This indicates that the mycotoxin production depended more on weather conditions than on the distribution of corresponding toxigenic fungal species., Agroekološki i klimatski uslovi u Srbiji veoma su pogodni za razvoj toksigenih gljiva i njihovih mikotoksina u kukuruzu.

AB  - The species of the genus Aspergillus, A. flavus and A. parasiticus, are the most aflatoxin-producing fungi. All previous studies carried out under the production conditions of Serbia showed no presence of A. parasiticus on wheat kernel. On the basis of changes in climatic factors, such as occurrence of high temperatures and prolonged droughts, which favour increased frequency of Aspergillus spp., we assumed that this pathogen can also be present in Serbia. The significance of direct losses as a consequence of wheat kernel infection, as well as potential contamination with aflatoxins, have pointed out to the need to determine the presence of toxigenic potential of A. flavus and A. parasiticus isolates originating from Serbia. For that purpose, wheat kernel samples were collected in nine locations. According to morphological, toxicological and molecular traits of isolated fungi, the presence of A. flavus and A. parasiticus was confirmed. This is the first time that A. parasiticus was identified on wheat under climatic conditions in Serbia. This study indicates that these pathogens may be a potential danger in wheat production in the region of Serbia. This danger will be much more certain if global climatic changes continue as they will provide more intensive development of these pathogens.

AB  - This study was carried out in order to investigate the natural occurrence of toxigenic fungi and levels of zearalenone (ZEA), deoxynivalenol (DON) and aflatoxin B1 (AFB1) in the maize stored immediately after harvesting in 2016 and used for animal feed in Serbia. A total of 22 maize samples were collected from four different districts across the country: City of Belgrade (nine samples), Šumadija (eight samples), Podunavlje (four samples) and Kolubara (one sample). Toxigenic fungi were identified according to the morphological characteristics whereas the mycotoxins contamination were detected using biochemistry enzyme-linked immuno-sorbent (ELISA) assay. The tested samples were mostly infected with Aspergillus, Fusarium and Penicillium spp., except that one sample originated from Kolubara was not contaminated with Aspergillus species. Fusarium graminearum was the most common species in the maize sample from Kolubara district (60%), F. verticillioides in the maize samples from Podunavlje (43.75%) and City of Belgrade (22.4%) districts, and Penicillium spp. in the maize samples from Šumadija district (26.38%). In the analysed maize samples the presence of Aspergillus species was low (0-1.78%). Mycotoxicological analysis revealed the presence of zearalenone (ZEA), deoxynivalenol (DON) and aflatoxin B1 (AFB1) in all the investigated samples, except that DON and AFB1 were not recorded in the samples from Podunavlje and Kolubara districts, respectively. The investigated samples were highly contaminated with ZEA, with incidence of 100% for the samples from Šumadija, Podunavlje and Kolubara districts and 88.89% for the samples from City of Belgrade district. In addition, the samples contamination with DON was 100% and 22.2% for the samples from Šumadija, Kolubara and City of Belgrade, districts, respectively. The highest number of AFB1 positive samples was found in Šumadija district (87.5%), while in the City of Belgrade and Podunavlje districts, 55.56% and 50% AFB1 positive samples were established, respectively. Generally, remarkable infection of all the tested samples with toxigenic fungal species from Aspergillus, Fusarium and Penicillium genera were recorded. In addition, high contamination with mycotoxins ZEA, DON and AFB1 were also recorded; nevertheless, only in one sample the level of DON exceeded the allowed legal limit (1750 μg kg-1 ) according to Regulation for unprocessed maize. Therefore, permanent mycological and mycotoxicological analyses of maize grain are necessary for risk assessment of fungal and mycotoxin contamination throughout the food chain.

Ukupno 22 uzoraka zrna kukuruza sakupljeni su iz četiri regiona u Srbiji: Beogradski (devet uzoraka), Šumadijski (osam uzoraka), Podunavski (četiri uzorka) i Kolubarski (jedan uzorak). Toksigene vrste gljiva su identifikovane na osnovu morfoloških osobina, a sadržaj mikotoksina određen je pomoću biohemijske, imunoadsorpcione enzimske metode (ELISA). Ispitivani uzorci kukuruza većinom su bili inficirani sa Aspergillus, Fusarium i Penicillium spp., izuzev što u uzorku iz Kolubarskog regiona nisu bile identifikovane Aspergillus vrste. Fusarium graminearum bila je najučestalija vrsta u uzorku kukuruza iz Kolubarskog regiona (60%), F. verticillioides u uzorcima iz Podunavskog (43,75%) i Beogradskog regiona (22,4%) i Penicillium spp. u uzorcima iz Šumadijskog regiona (26,38%). U ispitivanim uzorcima kukuruza zastupljenost Aspergillus vrsta bila je niska (0-1,78%). Mikotoksikološkim analizama ustanovljeno je prisustvo zearalenona (ZEA), deoksinivalenola (DON) i aflatoksina B1 (AFB1) u svim ispitivanim uzorcima kukuruza, izuzev što DON nije detektovan u uzorcima iz Podunavskog a AFB1 u uzorku iz Kolubarskog regiona.

Uopšteno razmatrajući, u ovim analizama ustanovljena je visoka zastupljenost toksigenih vrsta u svim ispitivanim uzorcima kukuruza. Isto tako, ustanovljena je visoka kontaminiranost uzoraka sa mikotoksinima ZEA, DON i AFB1, iako je samo u jednom uzorku sadržaj DON premašio dozvoljeni limit (1750 μg kg-1 ) prema zakonskoj regulativi za neprerađeni kukuruz. Zbog toga, stalne mikološke i mikotoksikološke analize zrna kukuruza neophodne su radi ocene rizika od gljivične i mikotoksin kontaminacije u lancu ishrane.

AB  - In this preliminary study, we used the Multivariate Curve Resolution- Alternating Least Squares (MCR-ALS) algorithm to analyze the excitation-emission matrix for different samples of maize flour contaminated with aflatoxin B1 (AFB1) - uncontaminated, low-contaminated, high-contaminated and flour from the local market. We intended to see if there are differences in emission spectral parameters that depend on degree of contamination. The analysis used genuine emission of the fluorophores in the flour, in absence and presence of AFB1, which enables fast screening of the samples, without sample pre-processing. As a result of the analysis, two fluorescence components were derived from the emission spectra for all analyzed samples. The components' positions were the same for the uncontaminated reference sample and the commercial flour sample from the local market, whereas for the samples contaminated with the aflatoxin B1, the emitted peaks' positions were red-shifted. We found that the ratio of the areas of these two components is proportional to the intensity of contamination: 0.071 for uncontaminated sample, 0.090 for the sample from local market, 0.192 for low-contaminated sample and 1.431 for high-contaminated sample. These results indicate that fluorescence EEM coupled with MCR-ALS could be used for rapid and simple estimation of the degree AFB1 contamination in maize flour.

abstract = "In this preliminary study, we used the Multivariate Curve Resolution- Alternating Least Squares (MCR-ALS) algorithm to analyze the excitation-emission matrix for different samples of maize flour contaminated with aflatoxin B1 (AFB1) - uncontaminated, low-contaminated, high-contaminated and flour from the local market. We intended to see if there are differences in emission spectral parameters that depend on degree of contamination. The analysis used genuine emission of the fluorophores in the flour, in absence and presence of AFB1, which enables fast screening of the samples, without sample pre-processing. As a result of the analysis, two fluorescence components were derived from the emission spectra for all analyzed samples. The components' positions were the same for the uncontaminated reference sample and the commercial flour sample from the local market, whereas for the samples contaminated with the aflatoxin B1, the emitted peaks' positions were red-shifted. We found that the ratio of the areas of these two components is proportional to the intensity of contamination: 0.071 for uncontaminated sample, 0.090 for the sample from local market, 0.192 for low-contaminated sample and 1.431 for high-contaminated sample.

AB  - Fusarium graminearum as the main causal agent of Fusarium head blight (FHB) and its ability to produce trichothecenes was investigated by molecular techniques. A total of 37 strains isolated from the wheat, harvested in Serbia in 2005, 2008 and 2015, and previously designated by morphological observation as F. graminearum, were used for trichothecene genotypes characterization. The strains were identified using the species-specific primer set FG16R/FG16F while genotypic characterization was done using specific TRI13 and TRI3 sequences of the trichothecene gene clusters. The PCR assays identified all strains as species of F. graminearum sensu stricto with the DON/15-ADON genotype. The quantification of the mycotoxin (DON) was performed using the biochemical assay. The high levels of DON (>20,000 mu g kg(-1)) were recorded in all of the strains from 2005, four strains from 2008 and two strains from 2015. Weather data of the investigated seasons, showed that the optimal temperature, frequent rains and high relative humidity (RH) was very favourable for the development of F. graminearum, affecting the DON biosynthesis.

AB  - Aflatoxin B1 (AFB1), ochratoxin A (OTA), zearalenone (ZON), deoxynivalenol (DON) and T-2 toxin are the most extensively studied toxic fungal metabolites. Once mycotoxins enter the food/feed production chain keeping their toxic characteristics, it is very difficult to remove or eliminate them. One of promising methods to reduce mycotoxins in contaminated food/feedstuffs is the use of mycotoxin binders. This paper presents the results of in vitro investigations of mineral mycotoxin binders (bentonite - BEN, diatomite - DIA and zeolite - ZEO), and organic mycotoxin binders - agricultural waste materials (Myriophillium spicatum, peach and sour cherry pits). Chemical compositions of the adsorbents have showed that they do not consist of elements toxic to the animals. Inorganic adsorbents (BEN, DIA and ZEO) tested in vitro were better binders of AFB1 (94.97% - 96.90%), while the biosorbents were more efficient in adsorption of OTA (19.98% - 66.66%), ZON (33.33% - 75.00%) and T-2 toxin (16.67% - 50.00%). Inorganic adsorbents and organic waste materials expressed similar binding capacity for DON in vitro, with the exception of M. spicatum that did not at all adsorb this type B trichothecene. Our results indicate that feed contamination with different types of mycotoxins might be diminished by a product that combines different inorganic and organic adsorbents with diverse mycotoxin binding properties.
AB  - Aflatoksin B1 (AFB1), ohratoksin A (OTA), zearalenon (ZON), dezoksinivalenol (DON) i T-2 toksin su najviše izučavani toksični metaboliti gljiva. Kada mikotoksini uđu u proizvodni lanac za hranu/hranu za životinje, zadržavajući svoje toksične karakteristike, teško ih je ukloniti ili eliminisati. Jedna od obećavajućih metoda za smanjenje nivoa mikotoksina u kontaminiranoj hrani/hrani za životinje je korišćenje mikotoksinskih veziva. Ovaj rad predstavlja rezultate in vitro istraživanja mineralnih mikotoksinskih veziva (bentonit - BEN, diatomit - DIA i zeolit - ZEO) i organskih veziva mikotoksina - poljoprivrednog otpadnog materijala (Myriophillium spicatum, koštice breskve i višnje). Hemijski sastavi adsorbenata pokazali su da ne sadrže elemente toksične za životinje.

AB  - Maize is considered one of the most susceptible crops to mycotoxins worldwide. Compared to other mycotoxins, the greatest attention has been paid to aflatoxins, due to their potential carcinogenicity and due to significant and longstanding problems they can cause in humans and animals. A. flavus and A. parasiticus produce aflatoxins in many economically significant crops in both fields and storages. Because of the potential aflatoxin contamination of maize grain, the toxigenic potential of A. flavus and A. parasiticus isolates, originating from Serbia, was tested in the present study. Furthermore, various applied methods for detection of these mycotoxins were compared in the study. Cultural, serological and analytical methods for the detection of mycotoxins were compared in the course of the experiment by the direct extraction of aflatoxins from the nutrient medium. The cultural methods for the detection of aflatoxin production were applied to 20 isolates of A. flavus (MRIZP Af18-20) and A. parasiticus (MRIZP Ap1-17). These methods are based on the yellow pigment formation in mycelia and nutrition media, occurrence of fluorescence on PDA (potato dextrose agar), agar containing β-cyclodextrine (CD-PDA), as well as on the red pigment formation after adding ammonium hydroxide to the existing medium. The ELISA was used to check quantitative and qualitative analyses of total aflatoxins (B1, B2, G1, G2) while the HPLC method was applied to establish ability of isolates to synthesize aflatoxins B1, B2, G1, G2. The yellow pigment formation, fluorescence and colony color changes of isolates into red, as a proof of toxigenicity of isolates, were confirmed in all cases by ELISA. A high potential of total aflatoxin production was determined in the majority of observed isolates. The ability of A. parasiticus isolates to synthesize aflatoxins G1 and G2 was confirmed by the HPLC method. This was essential for a better understanding of the key role of the suitability of cultural methods for preliminary evaluation of a large number of isolates. Our goal was to employ rapid biochemical approaches to prevent aflatoxin contamination of crops, and to reduce human and animal exposure to foodborne mycotoxins.
AB  - Kukuruz se širom sveta smatra jednim od useva najpodložnijih za kontaminaciju mikotoksinima. Aflatoksinima se, u poređenju s drugim mikotoksinima, pridaje najveća pažnja zbog njihove potencijalne kancerogenosti, značajnih i dugoročnih problema koje izazivaju kod ljudi i životinja.

Zbog potencijalne kontaminacije zrna kukuruza aflatoksinima u ovom radu je ispitan toksigeni potencijal izolata upravo ove dve vrste poreklom iz Srbije i upoređene su različite metode detekcije ovih mikotoksina. Tokom eksperimenta upoređene su odgajivačke, serološke i analitičke metode detekcije mikotoksina, direktnom ekstrakcijom aflatoksina iz hranljive podloge. Istraživanja su bazirana na primeni odgajivačke metode za određivanje produkcije aflatoksina kod 20 izolata A. parasiticus (MRIZP Ap1-17) i A. flavus (MRIZP Af18-20) poreklom iz Srbije. Odgajivačke metode su bile zasnovane na formiranju žutog pigmenta u miceliji i hranljivoj podlozi, na pojavi fluorescencije na PDA (krompir dekstrozni agar) i podlozi koja sadrzi β-ciklodekstrin (CD-PDA), kao i na obrazovanju crvenog pigmenta u podlozi nakon dodavanja amonijum hidroksida. ELISA test je korišćen za proveru kvantitativnih i kvalitativnih sadržaja ukupnih aflatoksina B1, B2, G1 i G 2, dok je HPLC metodom utvrđena koncentracija pojedinačnih aflatoksina B1, B2, G1 i G2. Obrazovanje žutog pigmenta, fluorescencija i promena boje kolonije izolata u crvenu, kao dokaz toksigenosti izolata, potvrđena je u svim slučajevima i ELISA testom. Kod većine izolata ustanovljen je visok potencijal produkcije ukupnih aflatoksina. HPLC metodom potvrđena je i sposobnost sinteze aflatoksina G1 i G2 od strane izolata A. parasiticus. Cilj eksperimenta bio je da se ispita efikasnost upotrebe brzih testova za detekciju aflatoksina, kako bi se sprečila kontaminacija useva i izloženost ljudi i životinja afla-toksinima.

AB  - Diversity of trichothecene chemotypes of Fusarium graminearum isolated from kernels of wheat, barley and maize grown under various agro-ecological conditions on 13 locations was analysed. Sixteen strains were tested for the effective capability to produce 15-ADON, 3-ADON and NIV, by using the liquid chromatography-tandem mass spectrometry (LC-MS/MS) system. Fourteen out of sixteen analyzed strains produced 15ADON, while remaining two were of the 3-ADON chemotype. Multiplex PCR reaction with two sets of specific primers for TRI3 and TRI12 genes was applied to identify trichothecene chemotypes (3-ADON, 15-ADON and NIV). The expected sizes of amplified fragments for TRI3 gene primer set are 840 bp (NIV), 610 bp (15-ADON) and 243 bp (3-ADON). The amplified fragments for TRI12 gene primer set should be 840 bp (NIV), 670 bp (15-ADON) and 410 bp (3-ADON). All F. graminearum isolates were of the 15-ADON chemotype, i. e. their bands were 610 bp and 670 bp size for TRI3 and TRI12 genes, respectively. The results indicate that genotypic characterisation does not correspond to determined chemotypes and this is a reason why the analyses for the risk of mycotoxins contamination should not be based only on trichotecene genotype determination. Due to high temperature differences in cereal growing regions in Serbia, the presence of other chemotypes could be expected. In order to determine whether besides 15-ADON there are other F. graminearum chemotypes on wheat, barley and maize kernels, further studies should include a large number of isolates from different agro-ecological conditions.

AB  - The aim of this study was to determine the presence of fungi and concentrations of mycotoxins, zearalenone, fumonisin and deoxynivalenol, in lucerne and grass-legume silages, under the influence of different doses of N fertilization and harvesting at different stages of phenological development of the plants. Studies included pure lucerne crop and mixtures of lucerne with cocksfoot, tall fescue and sainfoin, sown in different ratios, fertilized with 0, 70, 140 or 210 kgN ha(-1) and harvested in the butonization phase or at 50% flowering of lucerne plants. Results showed that the total fungi count in the silage depended on the three investigated factors. The highest total fungi count was determined in the mixture silages of lucerne, cocksfoot and tall fescue, which was well treated with different nitrogen quantities, harvested and prepared in later stages of plant development. The most commonly-occurring fungi were Fusarium species (85.5% of fungi were this genus). Of the studied mycotoxins, only DON depended on fertilization, as it reduced the concentration of DON from 0.15 to 0.07 mg kg(-1). Preventing appearance of fungi and their mycotoxins in forage and silage should begin in the field as well as during the process of preparation of silage.

AB  - Species of the genus Fusarium are predominant pathogens in cereals worldwide, while F. graminearum is the most distributed among them. This species synthesises a broad spectrum of mycotoxins (fusariotoxins), among which, trichothecene type B (deoxynivalenol-DON) and zearalenone (ZEA) prevail. The isolates from the collection of the Laboratory of Phytopathology of the Maize Research Institute, Zemun Polje were used to study diversity of the F. graminearum species. Twelve selected isolates were collected in the 2005-2016 period from wheat and barley kernels in various locations in Serbia. The aim of this study was to observe variability of the F. graminearum species regarding isolate pathogenicity, mycelium growth, macroconidium size, as well as DON and ZEA production potential by the ELISA method. All the observed isolates indicated pathogenic potential in the field and expressed different viability ranging from 1.75 to 3.75. Besides different viability, microscopic and macroscopic properties of isolates also diverged. The isolates of F. graminearum produced average concentrations of DON amounting 119. 9 and 33.4 ug/g (isolates from wheat and barley, respectively), while the average concentration of ZEA was 40.14 ug/kg (isolates from wheat) and 31.25 ug/kg (isolates from barley). A correlation between production of DON and ZEA was not observed in the isolates of F. graminearum.

Odabrano je 12 izolata koji su prikupljeni u periodu od 2005. do 2016. godine, poreklom sa zrna pšenice i ječma iz različitih lokaliteta na teritoriji Srbije. Cilj rada je bio da se ispita varijabilnost vrste F. graminearum u pogledu patogenosti izolata, porasta micelije, veličine makrokonidija kao i u potencijalu produkcije DON i ZEA pomoću ELISA metode. Svi ispitivani izolati su ispoljili patogenost u polju uz različit stepen agresivnosti koja je varirala od 1,75 do 3,75 (na skali 1-7). Pored varijabilnosti u agresivnosti izolati su bili divergentni i u mikroskopskim i makroskopskim karakteristikama. Izolati F. graminearum su produkovali prosečne koncentracije DON-a 119,9 ug/g (izolati sa pšenice) i 33,4 ug/g (izolati sa ječma), dok je prosečna koncentracija ZEA kod izolata sa pšenice bila 40,14 ug/kg, a kod izolata sa ječma 31,25 ug/kg.

AB  - In this study, the total fungal count and contamination with toxigenic fungi from Aspergillus, Fusarium and Penicillium genera of 127 maize grain samples collected from animal farms in subrbs of Belgrade area during 2012-2015, were determined. The total fungal count was determined using a dilution method, and standard mycological procedures were used to identify potential toxigenic fungi genera. In the tested samples of maize grains, the total fungal count was from 1 x 101 to 3 x 106 cfu g-1. No statistically significant differences between investigated years in regard to the mean total fungal count were determined. According to the Regulation on the quality of animal feed of the Republic of Serbia, the total fungal count above permitted limit (2 x 105 cfu g-1) was established in 9.52, 7.89, 20.69 and 55.56% tested samples in 2012, 2013, 2014 and 2015, respectively. Potentially toxigenic fungi from Aspergillus, Fusarium and Penicillim genera have been identified as the most common in all the samples. In most of the samples, based on the average value for the four-year period (2012-2015), Fusarium species (92.22%) have been identified, followed by the species of the genera Aspergillus (80.83%) and Penicillium (48.68%). A weak positive correlation was established between the moisture content of the samples and the total fungal count in 2012 (r=0.41), in 2013 (r=0.27) and in 2014 (r=0.36) and the medium positive correlation (r=0.61) in 2015. Based on the results of mycological analysis of grain maize it can be concluded that the test samples in a relatively large number did not meet the criteria of hygienic quality. Therefore, regular and continuous control of the mycological quality of maize grain as the most important nutrient in animal nutrition is necessary as a preventive measure to reduce and control contamination of grain with mycotoxigenic fungi.
AB  - Ukupan broj gljiva i kontaminacija s potencijalno toksigenim vrstama iz rodova Aspergillus, Fusarium i Penicillium određivani su u 127 uzoraka zrna kukuruza koji su sakupljeni na farmama u okolini Beograda tokom četvorogodišnjeg perioda (2012-2015). Primenom metode razređenja određen je ukupan broj gljiva, dok su standardne mikološke metode korišćene za identifikaciju potencijalno toksigenih rodova gljiva. U ispitivanim uzorcima zrna kukuruza ukupan broj gljiva je bio od 1 x 101 do 3 x 106 cfu g-1. Između ispitivanih godina nisu ustanovljene statističke značajne razlike u prosečnim vrednostima ukupnog broja gljiva. Prema Pravilniku Republike Srbije o kvalitetu hrane za životinje, u hranivima biljnog porekla, ukupan broj gljiva iznad dozvoljenog limita (2 x 105 cfu g-1) ustanovljen je u 9,52, 7,89, 20,69 i 55,56% ispitivanih uzoraka u 2012., 2013., 2014. i 2015. godini, respektivno. Od potencijalno toksigenih gljiva identifikovane su Aspergillus, Fusarium i Penicillim vrste kao najučestalije u svim ispitivanim uzorcima. U najvećem broju uzoraka, na osnovu prosečnih vrednosti u četvorogodišnjem periodu (2012-2015), identifikovane su Fusarium vrste (92.22%), zatim vrste iz rodova Aspergillus (80.83%) i Penicillium (48.68%). Između sadržaja vlage ispitivanih uzoraka i ukupnog broja gljiva ustanovljena je slaba pozitivna korelacija u 2012. (r=0.41), 2013. (r=0.27) i 2014. godini (r=0.36) i srednje pozitivna korelacija (r=0.61) u 2015. godini. Na osnovu dobijenih rezultata mikološke analize zrna kukuruza može se zaključiti da ispitivani uzorci u relativno velikom broju ne zadovoljavaju kriterijume higijenskog kvaliteta. Zbog toga, redovna i stalna kontrola mikološkog kvaliteta zrna kukuruza kao najvažnijeg hraniva u ishrani životinja je neophodna preventivna mera za smanjenje i kontrolu kontaminacije zrna s mikotoksigenim gljivama.

According to the Regulation on the quality of animal feed of the Republic of Serbia, the total fungal count above permitted limit (2 x 105 cfu g-1) was established in 9.52, 7.89, 20.69 and 55.56% tested samples in 2012, 2013, 2014 and 2015, respectively. Potentially toxigenic fungi from Aspergillus, Fusarium and Penicillim genera have been identified as the most common in all the samples. In most of the samples, based on the average value for the four-year period (2012-2015), Fusarium species (92.22%) have been identified, followed by the species of the genera Aspergillus (80.83%) and Penicillium (48.68%). A weak positive correlation was established between the moisture content of the samples and the total fungal count in 2012 (r=0.41), in 2013 (r=0.27) and in 2014 (r=0.36) and the medium positive correlation (r=0.61) in 2015. Based on the results of mycological analysis of grain maize it can be concluded that the test samples in a relatively large number did not meet the criteria of hygienic quality. Therefore, regular and continuous control of the mycological quality of maize grain as the most important nutrient in animal nutrition is necessary as a preventive measure to reduce and control contamination of grain with mycotoxigenic fungi., Ukupan broj gljiva i kontaminacija s potencijalno toksigenim vrstama iz rodova Aspergillus, Fusarium i Penicillium određivani su u 127 uzoraka zrna kukuruza koji su sakupljeni na farmama u okolini Beograda tokom četvorogodišnjeg perioda (2012-2015). Primenom metode razređenja određen je ukupan broj gljiva, dok su standardne mikološke metode korišćene za identifikaciju potencijalno toksigenih rodova gljiva. U ispitivanim uzorcima zrna kukuruza ukupan broj gljiva je bio od 1 x 101 do 3 x 106 cfu g-1. Između ispitivanih godina nisu ustanovljene statističke značajne razlike u prosečnim vrednostima ukupnog broja gljiva. Prema Pravilniku Republike Srbije o kvalitetu hrane za životinje, u hranivima biljnog porekla, ukupan broj gljiva iznad dozvoljenog limita (2 x 105 cfu g-1) ustanovljen je u 9,52, 7,89, 20,69 i 55,56% ispitivanih uzoraka u 2012., 2013., 2014. i 2015. godini, respektivno. Od potencijalno toksigenih gljiva identifikovane su Aspergillus, Fusarium i Penicillim vrste kao najučestalije u svim ispitivanim uzorcima. U najvećem broju uzoraka, na osnovu prosečnih vrednosti u četvorogodišnjem periodu (2012-2015), identifikovane su Fusarium vrste (92.22%), zatim vrste iz rodova Aspergillus (80.83%) i Penicillium (48.68%). Između sadržaja vlage ispitivanih uzoraka i ukupnog broja gljiva ustanovljena je slaba pozitivna korelacija u 2012. (r=0.41), 2013. (r=0.27) i 2014. godini (r=0.36) i srednje pozitivna korelacija (r=0.61) u 2015. godini. Na osnovu dobijenih rezultata mikološke analize zrna kukuruza može se zaključiti da ispitivani uzorci u relativno velikom broju ne zadovoljavaju kriterijume higijenskog kvaliteta. Zbog toga, redovna i stalna kontrola mikološkog kvaliteta zrna kukuruza kao najvažnijeg hraniva u ishrani životinja je neophodna preventivna mera za smanjenje i kontrolu kontaminacije zrna s mikotoksigenim gljivama.",

AB  - The production of fumonisins by potentially toxigenic Fusarium verticillioides isolates originating from Serbian maize and wheat kernels was tested in vitro. A total of six F. verticillioides isolates were incubated on yeast extract sucrose medium (YESA) for 4 weeks at 25 °C in the dark. Their toxin production potential was tested by applying a modified HPLC method for determination of fumonisins in cereals, since the TLC method gave no results. Analyses were performed on a HPLC-FLD system after sample extraction from YESA and extract clean-up on a SPE column. Although the isolates were tested for fumonisin B1, B2 and B3, only fumonisin B1 was detected. The results showed that all tested isolates had toxigenic potential for fumonisin B1 production. The average fumonisin B1 production of the isolates ranged from 7 to 289 µg/kg, thus indicating a highly variable toxigenic potential among the isolates. Isolate 1282 expressed the highest toxigenic potential for fumonisin B1 production (289 µg/kg), while isolate 2533/A showed a questionable potential for fumonisin production (7 µg/kg).
AB  - Proizvodnja fumonizina kod potencijalno toksikogenih Fusarium verticillioides izolata sa zrna kukuruza i pšenice poreklom iz Srbije testiran je in vitro. Ukupno šest izolata F. verticillioides inkubirano je na agarizovanoj podlozi sa ekstraktom kvasca i saharozom (YESA) tokom četiri nedelje, u mraku na 25 °C. Kapaciteti odabranih izolata za proizvodnju toksina detektovani su primenom modifikovane HPLC metode za određivanje fumonizina u zrnu žitarica, jer brza trijažna TLC metoda nije dala pozitivne rezultate. Analiza je izvedena na HPLC-FLD sistemu nakon ekstrakcije uzorka iz YESA kultura izolata i prečišćavanja ekstrakta na SPE koloni. Sve analize su urađene u tri ponavljanja. Iako su izolati F. verticillioides testirani na prisustvo fumonizina B1, B2 i B3, samo je fumonizin B1 bio detektovan. Rezultati su pokazali da svi testirani izolati imaju potencijal u sintezi fumonizina B1. Prosečna vrednost proizvedenog fumonizina B1 kod izolata F. verticillioides kretala se od 7 do 289 µg/kg, što ukazuje na izuzetno varijabilan toksigeni potencijal istih izolata. Izolat označen sa 1282 pokazao je najveći potencijal za biosintezu fumonizina B1 (289 µg/kg), dok je izolat 2533/A ispoljio diskutabilan potencijal za proizvodnju istog fumonizina (7 µg/kg).
