Aflatoxins are natural contaminants of food crops implicated in the pathogenesis of various human diseases. This study aimed to determine the associations between aflatoxins and proteinenergy malnutrition (PEM) by measurements of aflatoxins in serum, urine and food on plate of Nigerian children with PEM. A crosssectional study was undertaken in 3 agroecological regions of Nigeria (Guinea savann...

Aflatoxin B1-induced liver lesion development is readily modified by dietary protein intake. Earlier work had shown that low-protein diets enhanced the acutely toxic lesion but depressed the carcinogenic lesion. This study examined the emergence of these lesions as a function of dietary protein intake, particularly with respect to whether the protein modification occurred during or after the af...

The current research work aimed to access the contamination level of aflatoxins B1, B2, G1, and G2 in the household spices that are widely consumed in huge amounts. 200 different spice samples, 100 packed and 100 unpacked, were analyzed for the aflatoxins profile by HPLC with an incidence of 61.5% contamination out of which 53.66% samples exceed the EU limit. The results disclosed that the unpa...

We report a single, reliable, non-invasive analytical method for monitoring the fetal level of exposure to different mycotoxins. We assessed by tandem mass spectrometry levels up to 200 nanog/l for ochratoxin A and 500 nanog/l for aflatoxins in sample of serum (n= 71), urine (n= 18) and amniotic fluid (n= 21) of pregnant women. Aflatoxin G1 was present in one sample of serum (3.48 microg/l) and...

The aim of this study was to investigate the toxic effects of aflatoxins and evaluate the effectiveness of Bacillus subtilis ANSB060 in detoxifying aflatoxicosis in broilers. A total of 360 one-week-old male broilers (Ross 308) were assigned to six dietary treatments for five weeks. The treatment diets were: C0 (basal diet); C1.0 (C0 + 1.0 g B. subtilis ANSB060/kg diet); M0 (basal diet formulat...

Aflatoxins and their animal biotransformation products were screened for carcinogenic potential using the Ames' in vitro microbial detection system for carcinogens as bacterial mutagens [B. N. Ames et al. (1973) Proc. Natl. Acad. Sci. USA 70,2281-2285]. Aflatoxicol, aflatoxins G1 and M1, aflatoxicol H1, and aflatoxins Q1, B2, P1, G2, B2a, and G2a, listed in order of decreasing mutagenic potency...

Blood and urine samples from 252 Sudanese children were investigated for their aflatoxin content by high-performance liquid chromatography. The children comprised 44 with kwashiorkor, 32 with marasmic kwashiorkor, 70 with marasmus, and 106 age-matched, normally nourished controls. Aflatoxins were detected more often and at higher concentrations in sera from children with kwashiorkor than in the...

Aflatoxins have been shown to induce hepatotoxicity in animal models, but the effects of aflatoxin B2 (AFB2) on broiler hepatocytes is unclear. This study aimed to investigate the effects of AFB2 on apoptosis and autophagy to provide an experimental basis for understanding the mechanism of aflatoxin-induced hepatotoxicity. One hundred-twenty Cobb500 broilers were allocated to four groups and ex...

Aflatoxins are natural fungi toxins that have originated from Aspergillous fungi and secondary metabolites of moulds such as Aspergillus flavus and A. parasiticus. These toxins can be carcinogenic if they enter the body through food. Alfatoxin toxins can cause tissue necrosis, hepatic cirrhosis and liver cancer. Observed clinical signs in human including: regurgitation, cramp, acute hepatic les...
