Comparative Study of Different Patterns of Aflatoxinogenicity in Subfamily Circulatory Aspergillosis in Northern Iran

This study aimed to compare the virulence of Aspergillus toxins sircumdate sector in the north of the most important habitats and the habitats of many food products was conducte. samples of cultivation and processing centers in three geographic regions east gilan, mazandaran and gilan west collected. And in particular contexts and standardized (ICPA) chapk deux agar, chapk intended extract agar (with and without 20 % sucrose), malt extract agar agar and chapk deux (with and without 20 % sucrose) were isolated and identified. the species Aspergillus flavus, Aspergillus parasiticus, Aspergillus niger, Aspergillus umigatus, Aspergillus alliaceus, Aspergillus wentii, Aspergillus niveus, Aspergillus candidus, Aspergillus melleus, Aspergillus alliaceus, obtained by measuring the toxin job to another special substrates were cultured , then, cell extracts were prepared, the size of aflatoxin in the extracts was determined by direct competitive ELISA, 57 extracts obtained of toxin -producing strains of the 27 cases of air fields and 30 of the air processing factories were on two occasions by both ELISA kit by brand Ridascreen and AgraQuant were assessed . Aflatoxin levels measured farms and factories in east gilan the rest are more places.
