Bacterial Endotoxins

Microbial Toxins, Volume IV: Bacterial Endotoxins covers a general introduction of bacterial endotoxins, as well as research concerning structure (both morphological and physical), chemistry, immunology, biosynthesis, and genetics of bacterial endotoxins. The book describes the general characteristics of bacterial endotoxins; the anatomy and chemistry of Gram-negative cell envelopes; and the physical structure of bacterial lipopolysaccharides. The text also discusses the isolation and chemical and immunological characterization of bacterial lipopolysaccharides; the chemistry of the unique carbohydrates of bacterial lipopolysaccharides; and the relation of bacteriophage attachment to lipopolysaccharide structure. The chemical and biological heterogeneity of endotoxins, as well as the biosynthesis of the core region of lipopolysaccharide are also considered. The book further tackles the biosynthesis of O-antigens and the genetic aspects of biosynthesis and structure of Salmonella lipopolysaccharide. Microbiologists, biochemists, bacteriologists, immunologists, and people involved in biochemical research will find the book useful.
