MUCOPOLYSACCHARIDES PRODUCED BY A STRAIN OF CLOSTRIDIUM PERFRINGENS

Characteristics of a bacteriocin -like substance produced by Clostridium haemolyticum strain IRP - 135

Some properties of Beta Toxin produced by Clostridium haemolyticum strain IRP 13

Actin-specific ADP-ribosyltransferase produced by a Clostridium difficile strain.

By screening possible ADP-ribosyltransferase activities in culture supernatants from various Clostridium species, we have found one Clostridium difficile strain (CD196) (isolated in our laboratory) that is able to produce, in addition to toxins A and B, a new ADP-ribosyltransferase that was shown to covalently modify cell actin as Clostridium botulinum C2 or Clostridium perfringens E iota toxin...

Molecular Cloning of Clostridium Perfringens type B Vaccine Strain Beta Toxin Gene in E. coli

Clostridium perfringens is a gram-positive, obligate anaerobic bacterium, which is widely distributed in the environment. C. perfringens is subdivided to 5 groups (types A to E), based on its four major toxin (alpha, beta, epsilon and iota). C. perfringens type B beta toxin causes inflammation and bloody necrotic enteritis. Type B related enterotoxaemia is a major problem of veterinary sciences...

Identification and Characterization of a New Enterotoxin Produced by Clostridium perfringens Isolated from Food Poisoning Outbreaks

There is a strain of Clostridium perfringens, W5052, which does not produce a known enterotoxin. We herein report that the strain W5052 expressed a homologue of the iota-like toxin components sa and sb of C. spiroforme, named Clostridium perfringens iota-like enterotoxin, CPILE-a and CPILE-b, respectively, based on the results of a genome sequencing analysis and a systematic protein screening. ...
