Aflatoxin B1 in Feedstuffs

Zentralblatt für Veterinärmedizin Reihe B, 2010
Summary Cattle, sheep, poultry and swine feeds, protein concentrates, mineral, vitamin and antibiotic mixtures, Mikro and Polfamix additives, components, and other feeds (306 samples) were qualitatively and quantitatively investigated for the presence of aflatoxins. Out of all the samples aflatoxin contamination was found in 12.7% of assays. Poultry

Fungistatic action of aflatoxin B1

Experientia, 1967
La croissance des plusieurs especes d'Aspergillus et dePenicillium dans un milieu modifie de Czapek a ete inhibitee par l'aflatoxin B1. Cet arret de croissance pourrait etre annule en substituant au nitrate de sodium un extrait de levure comme source d'azote.

Activation and detoxication of aflatoxin B1

Mutation Research/Fundamental and Molecular Mechanisms of Mutagenesis, 1998
Aflatoxin B1 (AFB1) is a potent hepatocarcinogen in experimental animals and a hazard to human health in several parts of the world. Implementation of rational intervention plans requires understanding of aspects of the roles of individual chemical steps involved in its disposition. AFB1 is activated to AFB1 exo-8,9-epoxide primarily by cytochrome P450

Binding of aflatoxin B1 to melanin

Food and Chemical Toxicology, 1988
Whole-body autoradiography of pigmented C57BL mice injected with 3H-labelled aflatoxin B1 (AFB1) showed a high degree of labelling of melanin-containing tissues, such as the melanin of eyes and hair follicles. The corresponding tissues in albino NMRI mice contained only low amounts of the label. Liquid chromatography of extracts of pigmented mouse eyes

Mitochondrial toxicity of aflatoxin B1

2023
This chapter discusses the toxicity of aflatoxin B1 (AFB1) on mitochondrial function. It starts with an overview of aflatoxins: what they are, where they are found, and the types that exist. The introduction also describes the routes of AFB1 exposure, biotransformation, metabolism, and excretion. Thereafter, the chapter explains the major toxic effects

Antineoplastic Activity of Aflatoxin B1

Nature, 1968
THE aflatoxins, a group of related mycotoxins produced by Aspergillus flavus, have been extensively evaluated for biological activity. They are carcinogenic in animals1–5. The aflatoxin B1 fraction has been teratogenic in hamsters6, probably mutagenic in micro-organisms7 and caused chromosome breakage in mammalian cell cultures7,8.

Fungal degradation of aflatoxin B1

Natural Toxins, 1999
A number of fungal cultures were screened to select an organism suitable to be used in the detoxification of aflatoxin B1. They were co-cultured in Czapek-Dox-Casamino acid medium with aflatoxin B1 producing Aspergillus flavus. Several fungal cultures were found to prevent synthesis of aflatoxin B1 in liquid culture medium. Among these Phoma sp., Mucor

Effect of antiserum against aflatoxin B1-bovine serum albumin complex on aflatoxin B1-induced lysogenesis

Mutation Research Letters, 1988
Escherichia coli K12 bacteria lysogenic for the lambda phage were used to study the effect of antiserum against aflatoxin B1-induced lysogenesis. The antiserum was obtained from rabbits immunized with water in oil emulsion of aflatoxin B1-bovine serum albumin complex (AFB1-BSA).
