background: activation of inflammatory cells can cause more chemicals induced-hepatotoxicity. aflatoxin b1 (afb1) is a fungal toxin that induces acute hepatotoxicity in humans and animals. this study was conducted to examine the effect of co-exposure lps and various aflatoxin b1 doses on the damage hepatic parameters in isolated perfused rat liver. methods: thirty-two male wistar rats (250-300g...

Feed safety becoming the main factor to produce good quality food. The purpose of this study was evaluate ability lactic acid bacteria in degrading aflatoxin B1, suppressing growth contaminant bacteria, and its application on feed. Biological degradation B1 (AFB1) liquid cultures Escherichia coli Saccharomyces aureus inhibition by Lactobacillus plantarum were examined. Fermentation corn for 24 ...

This study investigated aflatoxin B1 (AFB1) contamination in dairy cow feed and the risk management of AFB1 content in concentrates undertaken by feed industries in the Parmigiano Reggiano area. Data on aflatoxin contamination risk management applied in 29 feed industries were collected and the AFB1 content of 70 feed samples was analysed. Data were collected within the framework of a quality c...

Aflatoxins and melanins are the products of a polyketide biosynthesis. In this study, the search of potential inhibitors of the aflatoxin B1 (AFB1) biosynthesis was performed among compounds blocking the pigmentation in fungi. Four compounds-three natural (thymol, 3-hydroxybenzaldehyde, compactin) and one synthetic (fluconazole)-were examined for their ability to block the pigmentation and AFB1...

Background: Activation of inflammatory cells can cause more chemicals induced-hepatotoxicity. Aflatoxin B1 (AFB1) is a fungal toxin that induces acute hepatotoxicity in humans and animals. This study was conducted to examine the effect of co-exposure LPS and various aflatoxin B1 doses on the damage hepatic parameters in isolated perfused rat liver. Methods: Thirty-two male wistar rats (250-3...

Aflatoxin B1 (AFB1) is a potent carcinogen that causes growth stunting, immunosuppression and liver cancer in multiple species. The recent trend of replacing fishmeal with plant-based proteins in fish feed has amplified the AFB1 exposure risk in farm-raised fish. NovaSil (NS), a calcium montmorillonite clay, has previously been shown to reduce AFB1 bioavailability safely and efficaciously in se...

A 3-year comprehensive analysis of aflatoxin contamination in peanut butter was conducted in Zambia, sub-Saharan Africa. The study analyzed 954 containers of 24 local and imported peanut butter brands collected from shops in Chipata, Mambwe, Petauke, Katete, and Nyimba districts and also in Lusaka from 2012 to 2014. For analysis, a sample included six containers of a single brand, from the same...

A high-affinity IgM monoclonal antibody specific for aflatoxins was covalently bound to Sepharose 4B and used as a preparative column to isolate aflatoxin derivatives from the urine of people and experimental animals who had been exposed to the carcinogen environmentally or under laboratory conditions. Aflatoxin levels were quantified by radioimmunoassay and high-performance liquid chromatograp...

The fungal metabolites produced by Aspergillus flavus and Aspergillus parasiticus cause detrimental health effects on humans and animals. Particularly aflatoxin B1 (AFB1) is the most studied and a well-known global carcinogen, producing hepatotoxic, genotoxic and immunotoxic effects in multiple species. AFB1 is shown to provoke liver dysfunctioning by causing hepatocytes apoptosis and disturbin...

The mycological profile of the retail wheat flour selling in different markets at Jeddah (Kingdom of Saudi Arabia) was studied. The most common genera were Aspergillus (isolated from 70% of the tested samples), Penicillium (30%), Eurotium (14%), and in a lesser extent Fusarium (20%) and Alternaria (18%). Twenty-nine strains of Aspergillus flavus were screened for their ability to produce aflato...
