Sections: Enteric Gram-Negative Rods (Enterobacteriaceae): Introduction, Classification, Diseases Caused by Enterobacteriaceae other than Salmonella & Shigella, The Shigellae, The Salmonella-Arizona Group, References.
Topics Discussed: bacteriology; enterobacteriaceae; gastrointestinal infections and enterotoxigenic poisonings.
Excerpt:"The Enterobacteriaceae are a large, heterogeneous group of gram-negative rods whose natural habitat is the intestinal tract of humans and animals. The family includes many genera (Escherichia, Shigella, Salmonella, Enterobacter, Klebsiella, Serratia, Proteus, and others). Some enteric organisms, eg, Escherichia coli, are part of the normal flora and incidentally cause disease, while others, the salmonellae and shigellae, are regularly pathogenic for humans. The Enterobacteriaceae are facultative anaerobes or aerobes, ferment a wide range of carbohydrates, possess a complex antigenic structure, and produce a variety of toxins and other virulence factors. Enterobacteriaceae, enteric gram-negative rods, and enteric bacteria are the terms used in this chapter, but these bacteria may also be called coliforms...."
