Comparison of the levels of heat resistance of wild-type, cpe knockout, and cpe plasmid-cured Clostridium perfringens type A strains.
An enterotoxin (cpe) plasmid was cured from a Clostridium perfringens non-food-borne gastrointestinal disease (NFBGID) isolate, and the heat resistance levels of wild-type, cpe knockout, and cpe plasmid-cured strains were compared. Our results demonstrated that (i) wild-type cpe has no influence in mediating high-level heat resistance in C. perfringens and (ii) the cpe plasmid does not confer heat sensitivity on NFBGID isolates.
