Experiment on Isolation,Identification and Serological Detection of Haemophilus parasuis

在病史调查、临床症状、特征性病变观察、病料采集、细菌分离培养、生化鉴定的基础上,抽取贵州地区猪场发病猪群血样进行间接血凝试验检测。结果表明：贵州地区部分猪场存在副猪嗜血杆菌的感染,且感染率随着猪日龄的增长而降低,猪场平均感染幅度在10%~33%。

Based on medical history investigation,clinical symptoms,characteristic damages observation,disease collection,isolation and culture of bacterium and biochemical identification,taking blood samples of infected pigs from piggery in Guizhou area to carry on indirect haemagglutination test detection.The average results showed that parts of Guizhou area existed the infection of Haemophilus parasuis and infection rate decreased with increasing ages of pigs,the amount of infection in piggery was 10%~33%.
