Background: Aflatoxin contamination is a common natural phenomenon that is difficult to avoid or control and it can occur during pre and post-harvest periods under high humidity and temperature conditions, and are potentially dangerous to fish. In the present study, a feeding trial evaluated the effects of diets contaminated with aflatoxin on certain immunological parameters of common carp. Me...

Aflatoxins are highly carcinogenic mycotoxins frequently produced by Aspergillus flavus. Contamination of maize with aflatoxins imposes both economic and health burdens in many regions. Identification of the most important etiologic agents of contamination is complicated by mixed infections and varying aflatoxin-producing potential of fungal species and individuals. In order to know the potenti...

While soil application of a competitive non-toxigenic Aspergillus flavus strains is successful in reducing aflatoxin contamination in certain crops, direct application to aerial reproductive structures could be more effective for maize. A sprayable, clay-based water-dispersible granule formulation was developed to deliver non-toxigenic A. flavus strain K49 directly to maize ears. The efficacy o...

Extensive aflatoxin occurrence in corn both before and after harvest has prompted investigation to identify conditions contributing to crop infection by toxin-producing fungi. This presentation will attempt to summarize the preliminary observations of fungal-corn associations in the field in response to concern about this type of aflatoxin contamination. In the fall of 1972, a study of field co...

aspergillums can produce and secrete directly afla­toxin m1. during the previous decade several papers pertaining to aflatoxin m1 have been published in different journals. not mention of their more or less scientific aspects, they have fundamentally some problems in different features. in this paper we are going to have a bird's eye view on some articles published on this topic. it is suggeste...

background cereal products are susceptible to mould damage during pre- and post-harvesting stages of the production. the regional specificity of golestan province in the northern region of of iran, with its high temperature and high relative humidity, acts as a leading factor for the growth of aflatoxin-producing fungi. it is well known that contamination of starch-based ingredients with mycoto...

Aflatoxins are toxic and carcinogenic polyketide metabolites produced by certain fungal species, including Aspergillus flavus and A. parasiticus. Many internal and external factors, such as nutrition and environment affect aflatoxin biosynthesis; therefore, we analyzed the transcriptome of A. flavus using expressed sequence tags (ESTs) from a normalized cDNA expression library constructed from ...

Extraction of oil from poor quality pistachios results in increased add-value. In this study, the performance of different solvents in recovery of valuable oil and meal from the pistachio sample contaminated with aflatoxin was investigated and some chemical properties of the extracted oil were determined. The pistachio nut oil was extracted by three solvent systems including n-hexane (non- pola...

Aflatoxin contamination in the field is known to be influenced by numerous factors. Drought and high temperatures are conducive to Aspergillus flavus infection and aflatoxin contamination. This article will review the application of new molecular tools to study host resistance to *Correspondence: B. Z.

In the Rio Grande Valley of Texas (RGV), values of maize and cottonseed crops are significantly reduced by aflatoxin contamination. Aflatoxin contamination of susceptible crops is the product of communities of aflatoxin producers and the average aflatoxin-producing potentials of these communities influence aflatoxin contamination risk. Cropping pattern influences community composition and, ther...
