ENGLISH- Section 2 -- Microbial Hazards - Food safety. The present volume Bacterial Toxins: Methods and Pro- cols, is intended to fill this gap. Bacterial Toxins: Methods and Protocols consists of two sections: one on protein toxins (15 chapters) and one on endotoxins (5 chapters). Each s- tion is introduced by an overview article (Chapters 1 and 16). The protocols collected represent state-of-the-art techniques that each have high impact on, Bacterial Toxins General Aspects. Toxin type ; Exotoxinprotein produced by bacteria either excreted or bound to bacterial surface and released when lysed ; Endotoxinlps of the outer membrane of Gram bacteria ; Acts as toxin only under special circumstances; 4 Bacterial Toxins General Aspects. Specificity ; Some act on certain cell types ; Other affect wide range of cells and tissues ; Numbers.

Microbial toxins are toxins produced by micro-organisms, including bacteria and fungi. Microbial toxins promote infection and disease by directly damaging host tissues and by disabling the immune system. Some bacterial toxins, such as Botulinum neurotoxins, are the most potent natural toxins known. However, microbial toxins also have important uses in medical science and research. … Dear Colleagues: Bacterial toxins are classified into two major types: Endotoxins and exotoxins. Endotoxins are specifically referred to as cell-associated toxins—non-protein lipopolysaccharides associated with the cell wall of Gram negative bacteria.

Toxins may be classified as exotoxins (those excreted by an organism, for example, bufotoxin) or endotoxins (toxins that are structurally part of bacteria, for example, botulinum). The most toxic compound is the toxin botulinum. TOXIGENESIS Two types of bacterial toxins 1. Lipopolysaccharides: are associated with the cell walls of Gram-ve bacteria.

Others consider food poisoning as intoxication of food by chemicals or toxins from
