A total of 192 isolates of Clostridium perfringens were isolated from 99 broiler chickens and 93 capercaillies (Tetrao urogallus). Fifty of the isolates from broilers and 44 of the isolates from capercaillies were from birds with necrotizing enteritis, and the remainder were from birds without this disease. The isolates were tested for the production of three major toxins (alpha, beta, and epsilon) and four minor toxins (theta, gelatinase, mu, and nu). All isolates were found to be C. perfringens type A. Alpha toxin was produced in significantly larger amounts by isolates from birds with necrotizing enteritis than by isolates from birds without the disease, regardless of bird species. Isolates from broilers produced significantly more alpha toxin than did isolates from capercaillies.
从99只肉鸡和93只松鸡（西方松鸡）中总共分离出192株产气荚膜梭菌。其中，来自肉鸡的50株分离菌和来自松鸡的44株分离菌来自患有坏死性肠炎的鸟类，其余分离菌来自未患此病的鸟类。对这些分离菌进行了三种主要毒素（α、β和ε）和四种次要毒素（θ、明胶酶、μ和ν）产生情况的检测。所有分离菌均为A型产气荚膜梭菌。无论鸟类种类如何，患有坏死性肠炎的鸟类分离菌产生的α毒素量均显著高于未患此病的鸟类分离菌。肉鸡分离菌产生的α毒素显著多于松鸡分离菌。
