STUDIES OF THE L-FORMS OF CLOSTRIDIUM PERFRINGENS I

Studies of the L-forms of Clostridium perfringens. I. Relationship of colony morphology and reversibility.

The L-forms of Clostridium perfringens were first reported by Dienes (1950). He described this form as minute, soft, pleomorphic colonies which developed when C. perfringens were grown on penicillin-treated horse serum agar plates. The reversion of L-colonies to bacterial forms has not been reported for C. perfringens. They have been observed in strains of Proteus (Dienes, 1949), Salmonellae (W...

Clostridium perfringens in Cooling Rate Challenge Studies

Proper temperature control is essential in preventing Clostridium perfringens food poisoning. The U.S. Department of Agriculture Food Safety and Inspection Service cooling guidelines offer two options for the cooling of meat products: follow a standard time-temperature schedule or validate that alternative cooling regimens result in no more than a 1-log CFU/g increase of C. perfringens and no g...

Cloning of Clostridium perfringens iota toxin gene in Escherichia coli

Iota toxin is produced by Clostridium perfringens type E. This toxin causes antibiotic-associated enterotoxemia in lambs and calves. Iota toxin is a binary toxin that has two components including Ia (the enzyme component) and Ib (the binding component). Ib binds to the surface receptor of target cells and translocate Ia into the cytosol of cells. The aim of this study was to clone toxigenic epi...
