Five strains ofAspergillusfJavus lacking the ability to produce aflatoxins were examined in greenhouse tests for the ability to prevent a toxigenic strain from contaminating developing cottonseed with aflatoxins. All atoxigenic strains reduced contamination when inoculated into developing bolls 24 h prior to the toxigenic strain. However, only one strain, AF36, was highly effective when inocula...

Aflatoxins have long been suspected to be human hepatic carcinogens but no direct study was feasible until assays to measure individual aflatoxin exposure became available. We have used assays for urinary aflatoxin B1, its metabolites AFP1 and AFM1, and DNA-adducts (AFB1-N7-Gua) to assess the relation between aflatoxin exposure and liver cancer, as part of an ongoing prospective study of 18,244...

Many studies have shown that mycotoxin contamination of agricultural products is a challenge for individual's health especially in developing countries. Improper production and storage of foods, prepare conditions for aflatoxin production in crops, especially rice, wheat, pistachio, walnut, almond, etc which are the main sources of foods for people. Feeding livestock by contaminated bread is an...

Aflatoxin B₁, a type of highly toxic mycotoxin produced by some species belonging to the Aspergillus genus, such as Aspergillus flavus and Aspergillus parasiticus, is widely distributed in feed matrices. Here, coumarin was used as the sole carbon source to screen microorganism strains that were isolated from types of feed ingredients. Only one isolate (ND-1) was able to degrade aflatoxin B₁ aft...

Maize breeders continue to seek new sources of aflatoxin resistance, but most lines identified as resistance sources are late maturing. The vast difference in flowering time makes it hard to cross these lines with proprietary commercial lines that mature much earlier and often subjects the reproductive phase of these resistant lines to the hottest and driest portion of the summer, making silkin...

Corn naturally contaminated with 2,000 ppb total aflatoxin was adjusted to 17% moisture and ammoniated (Am) with 1.5% (w/w) anhydrous ammonia in an attempt at detoxification. The ammonia treatment reduced the detectable concentration to 510 ppb total aflatoxins. Ninety-six male Sprague-Dawley rats (75 g avg) were randomly divided into eight treatment groups with 12 rats per treatment. A fortifi...

The present experiment was carried out to examine the effect of aflatoxin exposure through experimentally contaminated feed (48 or 98 μg/kg feed) on hematological parameters, and gross histopathology liver, kidneys, thymus, spleen bursa fabricious in ducks, assess prophylactic efficacy bentonite clay at three different dose levels (1, 2 3g/kg protecting birds from toxic effects aflatoxin. 9 wee...

Since 2003, non-compliant aflatoxin concentrations have been detected in maize produced in Italy. The most successful worldwide experiments in aflatoxin prevention resulted from distribution of atoxigenic strains of Aspergillusflavus to displace aflatoxin-producers during crop development. The displacement results in lower aflatoxin concentrations in harvested grain. The current study evaluated...

Background: The main aim of the present study was to evaluate the ameliorative effect of curcumin on aflatoxin-induced changes in caput and cauda epididymis of mice. Materials and Methods: Aflatoxin was obtained by growing Aspergillus parasiticus in sucrose magnesium sulphate potassium nitrate yeast extract (SMKY) liquid medium. Pure curcumin (97% purity) was purchased from Hi-Media Laboratorie...
