Gene deletion patterns in non-aflatoxigenic isolates of Aspergillus flavus
Fifteen non-aflatoxigenic strains of Aspergillus flavus, represent a wide range of geographic regions of Iran (six provinces include Fars, Ardebil, Guilan, Golestan, Kerman and Semnan) and vegetative compatibility groups (VCGs), were collected from corn (Zea mays L.), peanut (Arachis hypogaea L.) and pistachio (Pistachia vera L.) soils and kernels, were screened for the presence of aflatoxin bi...
متن کاملCharacterization of aflatoxigenic Aspergillus flavus and A. parasiticus strain isolates from animal feedstuffs in northeastern Iran
Aflatoxins are secondary toxic metabolites produced by some Aspergillus spp. particularly, Aspergillus flavus and A. parasiticus that contaminate food and feed. The objective of this study was to evaluate the contamination of feedstuffs with Aspergillus spp. and detect genes involved in the aflatoxin biosynthesis pathway of A. flavus and A. parasiticus isolates. A total of 110 cow feed samples ...
متن کاملIdentification and Quantification of a Toxigenic and Non-Toxigenic Aspergillus flavus Strain in Contaminated Maize Using Quantitative Real-Time PCR
Aflatoxins, which are produced by Aspergillus flavus, are toxic to humans, livestock, and pets. The value of maize (Zea mays) grain is markedly reduced when contaminated with aflatoxin. Plant resistance and biological control using non-toxin producing strains are considered effective strategies for reducing aflatoxin accumulation in maize grain. Distinguishing between the toxin and non-toxin pr...
متن کاملIn vitro susceptibility of aflatoxigenic and non-aflatoxigenic Aspergillus flavus strains to conventional antifungal agents.
Presently appearance of resistance to antifungal agents among Aspergillus species is dramatically increasing. The objective of this study was to look at the in vitro activities of antifungal drugs against Iranian clinical (from nail, bronchoalveolar lavage, paranasal sinus) isolated A. flavus strains. The susceptibility of 45 aflatoxigenic and non-aflatoxigenic Aspergillus flavus strains were e...
