Abstract: This study aimed at the isolation, identification and treatment of the pathogen which was responsible for the sucking pig diarrhea that was epidemic in many provinces recently. The author conducted a comprehensive research using methods including the observation of the clinical symptoms, pathological anatomy, the isolation of the pathogen, bacterioscopy, the observation of the colonial configuration, biochemical identification, and animal testing. A single strain of Clostridium perfringens was isolated from the disease part of the sucking pig in many pig farms attacked by the disease and the potential prevention and treatment to the pathogen was explored. In result, the current severe sucking pig diarrhea had a close relation with the infection of Clostridium perfringens. The methods of treating Clostridium perfringens and inactivated vaccine produced by the farms had obvious positive results to the treatment and prevention of the disease respectively.

Key words: Clostridium perfringens; sucking pig diarrhea; identification of Clostridium perfringens
