Yamagishi, Takayoshi (Kanazawa University, Kanazawa, Japan), Shoichi Ishida, and Shoki Nishida. Isolation of toxigenic strains of Clostridium perfringens from soil. J. Bacteriol. 88:646-652. 1964-Strains of Clostridium perfringens were isolated from soil specimens heated at various temperatures for different lengths of time and were toxigenically examined. When higher temperatures were used, fewer toxigenic strains were isolated. Toxigenic strains could not be obtained from soil specimens heated at 100 C for 60 min. All toxigenic strains were killed by heating at 100 C for 10 min; strains that were resistant to these conditions were found to be nontoxigenic. These findings suggest that sporulating ability is closely linked to toxigenicity.

متن کاملOccurrence of Beta2 toxigenic Clostridium perfringens isolates with different toxin types in Iran
Clostridium perfringens is an important cause of enteric diseases in both human and animals. The bacteria produce several toxins which play key roles in the pathogenesis of diseases and are classified into five toxin types, on the basis of the differential production of Alpha, Beta, Epsilon and Iota toxins. In this study a single PCR assay was developed and used for detection of cpb2 gene to id...
