BACKGROUND Micronutrient deficiencies occur commonly in people infected with the human immunodeficiency virus. Since aflatoxin exposure also results in reduced levels of several micronutrients, HIV and aflatoxin may work synergistically to increase micronutrient deficiencies. However, there has been no report on the association between aflatoxin exposure and micronutrient deficiencies in HIV-in...

Effect of Activated Charcoal on the Fermentation Parameters and Degradability Contaminated Diet with Aflatoxin B1 by Microorganisms Isolated from Rumen In Vitro

A rapid, quantitative, inexpensive, and efficient method was developed to determine aflatoxins in corn, corn meal, popcorn, rice, wheat, cottonseed, and peanuts. Samples are ground and extracted with methanol-water (80 + 20). A portion of the extract is cleaned up by passage through a solid-phase separatory column, 500 microL purified extract is derivatized with a bromine reagent, and fluoresce...

The most frequent toxigenic fungi in the Europe are Aspergillus, Penicillium and Fusarium species. They produce aflatoxin B1 transformed into aflatoxin M1 found in the milk, as well as Ochratoxins and Zearalenone, Fumonisin B1, T-2 toxin, HT-2 toxin and deoxynivalenol (vomitoxin), which are of increasing concern in human health. These mycotoxins are under continuous survey in the Europe, but th...

This study aimed to prepare the basic components of aflatoxin B1 (AfB1) radioimmunoassay (RIA) technique using liquid phase to measureAfB1 in agricultural commodities. These components were polyclonal antibody (anti-AfB1), I-labelledAfB1 and aflatoxin B1 standards.Anti-AfB1 polyclonal was raised by immunizing six white New-Zealand rabbits with aflatoxin B1bovine serum albumin (AfB1-BSA) conjuga...

Fischer 344 rats readily develop liver cancer when exposed to aflatoxin B1 (AFB1) but dietary administration of the antioxidant ethoxyquin (EQ) provides protection against hepatocarcinogenesis. Chemoprotection by EQ is accompanied by the overexpression of enzymes which detoxify activated AFB1. Aflatoxin-protein adduct formation takes place following metabolism of AFB1 to the dialdehydic form of...

Moldy and split peanut kernels were separated from peanuts exported from Brazil, Sudan, India and Taiwan by visual inspection. The remaining peanuts from Brazil, Sudan and India were roasted lightly and the skins were removed. Stained peanuts were separated from the others. Aflatoxin was detected in moldy and stained peanuts. There was a positive correlation between % of aflatoxin-contaminated ...

the aims of the present study was to evaluate the level of aflatoxin b1 (afb1) in feedstuffs (corn silage, corn, dried alfalfa, cottonseed meal, cottonseed, soybean meal, canola meal, barley, wheat bran, concentrate, sugar beet pulp and wheat straw) that collected from dairy herds in khorasan razavi province that classified according to milk yield in very high (>10000 kg/day), high (5000-10000 ...

Peanut seeds were prepared with variations in roasting conditions. Positive correlations were obtained between loss of aflatoxins in the products and the roasting conditions. Seeds dryroasted at 140C for 40 min resulted in 58.8% and 64.5% reductions in AFB1 and AFG1, those roasted at 150C for 25 minutes resulted in 68.5% and 73.3% reductions in AFB1 and AFG1, respectively. Roasting at150C for 3...
