Abstract

Enterotoxin-positive strains of Clostridium perfringens were grown in Duncan-Strong sporulation medium in the presence of 0.4% (7.9 mM) raffinose at 37 and 43 degrees C. Enterotoxin- and heat-resistant spores were produced at similar concentrations but sooner at 43 degrees C than at 37 degrees C. There was a direct relationship between spore heat resistance and sporulation temperature (32, 37, and 43 degrees C).

摘要

产气荚膜梭菌的肠毒素阳性菌株在含有0.4%（7.9 mM）棉子糖的邓肯-斯特朗芽孢形成培养基中于37℃和43℃培养。产生的肠毒素和耐热芽孢浓度相似，但在43℃时比在37℃时产生得更快。芽孢耐热性与芽孢形成温度（32℃、37℃和43℃）之间存在直接关系。
