英文摘要：

Clostridium perfringens type C is the most pathogenic bacterium, which can lead to enterotoxaemia of piglets. Its pathogenic factor is alpha-toxin and beta-toxin. Detection methods, gene cloning and expression regulation ,relationship between structure and function of alpha-toxin and molecular biology of beta-toxin were introduced in this article.
