Clostridium perfringens: Avoiding diagnostic confusion

Toxin plasmids of Clostridium perfringens.

In both humans and animals, Clostridium perfringens is an important cause of histotoxic infections and diseases originating in the intestines, such as enteritis and enterotoxemia. The virulence of this Gram-positive, anaerobic bacterium is heavily dependent upon its prolific toxin-producing ability. Many of the ∼16 toxins produced by C. perfringens are encoded by large plasmids that range in si...

Serological Types of Clostridium perfringens.

In the flood of papers on the pathogenic anaerobes which appeared about 1920 several workers, particularly Zeissler (1919), Heller (1920), Hall (1922), came to the conclusion that agglutination reactions were of no value in the classification of the group. The apparent heterogenicity of strains of Clostridium perfringens has probably caused the greatest difficulty. Weinberg and Barotte (1928), ...

Glycosylating Toxin of Clostridium perfringens

Clostridium perfringens type C strains that produce various toxins cause hemorrhagic noxious ulceration or mucousal necrosis of the small intestine in humans, pigs, cattle and chickens (Sakurai et al. 1997, Sakurai and Nagahama 2006). In humans, the bacteria cause necrotic enteritis, which is termed “pig-bel” (Sakurai and Nagahama 2006). C. perfringens has been classified into five types, A to ...
