Eleven Clostridium perfringens type C strains isolated from fatal cases of hemorrhagic enterotoxemia of Canadian calves, a piglet, and a foal were studied for the production of soluble antigens. All the isolates from calves and a foal failed to produce delta toxin, but were capable of producing large amounts of lethal beta toxin. A strain isolated from a piglet produced delta, but very little beta toxin. Other differences were relatively minor. The results indicated that young domestic animals may be susceptible to all subtypes of C. perfringens type C. A simple method of using blood agar plates coated with type A antiserum for demonstration of hemolytic patterns was found advantageous in differentiation of C. perfringens strains.
对从加拿大犊牛、一头仔猪和一匹小马的出血性肠毒血症致死病例中分离出的11株C型产气荚膜梭菌菌株进行了可溶性抗原产生情况的研究。所有来自犊牛和一匹小马的分离株均未产生δ毒素，但能够产生大量致死性β毒素。从一头仔猪分离出的菌株产生δ毒素，但产生的β毒素很少。其他差异相对较小。结果表明，幼年家畜可能对C型产气荚膜梭菌的所有亚型敏感。发现一种使用涂有A型抗血清的血琼脂平板来展示溶血模式的简单方法，在区分产气荚膜梭菌菌株方面具有优势。
