objective: with consideration of lethal effects of aflatoxins specially b1 on human health. estimation of aflatoxin-albumin adduct, as an important marker of aflatoxin exposure, seems essential. the aim of this study is optimization of hplc-fluorescence method for measurement of this important marker in blood serum. materials and methods: in this study, blood serum of three groups of rats as a...
Toxic effects of Aflatoxin B1 on growth performance and humoral immune response against Newcastle disease Virus (NDV) vaccine were determined in Japanese quails. Quail chicks (n=300) were divided into five groups and each group was further sub-divided into two subgroups. One subgroup of each group was vaccinated with NDV vaccine to study the antibody response. Experimental diets were prepared b...
In this study, the treatment of pistachio nuts by Bacillus subtilis UTBSP1, a promising isolate to degrade aflatoxin B1 (AFB1), caused to reduce the growth of Aspergillus flavus R5 and AFB1 content on pistachio nuts. Fluorescence probes revealed that the cell free supernatant fluid from UTBSP1 affects spore viability considerably. Using high-performance liquid chromatographic (HPLC) method, 10 ...
Aegle marmelos leaves have been used for treatment of various liver aliments from time immemorial. Pre-treatment of A.marmelos leaves crude powder at its therapeutic dose (1000 mg/kg body weight) was carried out to determine the efficacy on aflatoxin B1 (AFB1) (1 mg/kg body weight) induced liver toxicity in rats. The crude powder of A.marmelos was found to be a potent inducer of the phase II de...
Aflatoxins (AFs) are highly toxic secondary metabolites produced by several Aspergillus, Penicillium and Rhizopus species in crops and plant products, of which aflatoxin B1 (AFB1) is the most representative (Goldblatt, 1969). If AFB1 is present in the feed of lactating animals, they will excrete aflatoxin M1 (AFM1) into their milk (Allcroft and Carnaghan, 1963; Cupid et al., 2004; Battacone et ...
Aflatoxin B1 (AFB1) is a highly toxic compound (LD50 = 1-50 mg/kg) for most animal species, although it is extremely toxic (LD50 < 1 mg/kg) for some highly susceptible species such as pigs, dogs, cats, rainbow trouts, and ducklings. The toxic effects of AFB1 are both dose and time dependent and two distinct forms of aflatoxicosis, namely acute and chronic, can be distinguished depending on the ...
BACKGROUND Aflatoxins are known contaminants of foods. High dose exposure, particularly to Aflatoxin B1 (AFB1) may cause acute aflatoxicosis. Outbreaks have been reported in developing nations but are virtually un-documented in the developed world. CASE REPORT A 28 year old, healthy male presented with nausea, vomiting and abdominal pain. The patient deteriorated rapidly to a state of agitati...
To evaluate the role of aflatoxin B1 (AFB1) exposure on risk of hepatocellular carcinoma (HCC), a case-control study nested within a community-based cohort was conducted. Baseline blood and urine samples were used to determine the level of AFB1-albumin adducts and urinary AFB1 metabolites. Conditional logistic regression analysis was used to calculate odds ratios (OR) and 95% confidence interva...
Nowadays, the separation of pistachios which seem to have aflatoxin is done according to their organoleptic physical qualities like color and etc. As these methods are not fully practical, and there is always a possibility of error and also the conditions like the wrong time harvest, the transportation of picked pistachios, the delay on the processing cause some contaminations in pistachios wh...
In the present study, the impacts of various concentrations of Aflatoxin B1 (AFB1) on Beluga, Huso huso, under controlled conditions were investigated. Belugas (120±10g) were fed on diets containing 0, 25, 50, 75, and 100 ppb AFB1/kg of diet for 3 months. Results showed various levels of AFB1 do not significantly affect the specific growth ratio (SGR) (P < 0.05) of fish in different treatments...
