从产气荚膜梭菌非食源性胃肠道疾病（NFBGID）分离株中治愈肠毒素（cpe）质粒，并比较野生型、cpe敲除和cpe质粒治愈菌株的耐热性水平。我们的结果表明，（i）野生型cpe对介导产气荚膜梭菌的高水平耐热性没有影响，并且（ii）cpe质粒不赋予NFBGID分离株热敏感性。
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.
