几例新型仔猪腹泻的诊治

Diagnosis and Treatment of Several Cases of Novel Sucking Pig Diarrhea

试验旨在对近来多省份流行的仔猪腹泻病原菌进行分离及鉴定,并研究其防治方法。通过临床症状观察、病理解剖、病原菌分离、镜检、菌落形态观察、生化鉴定、动物试验等方法对该病进行综合研究。从多个发病养殖场的腹泻仔猪病变部位分离到一株魏氏梭菌,并探索了其防治方法。结果表明,当前发生的严重仔猪腹泻与感染魏氏梭菌密切相关,采用治疗魏氏梭菌病的方法对该病进行治疗及利用灭活自场疫苗对其预防效果均明显。

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.
