Abstract:

为了明确青海省4个地区12个猪场副猪嗜血杆菌病的流行情况,应用间接血凝对不同猪场639份血清进行了检测;对疑似副猪嗜血杆菌病的15份病料进行了病原分离鉴定,应用琼脂扩散试验对分离菌进行了分型。结果4个地区副猪嗜血杆菌最高阳性率为58.73%,最低阳性率为0,平均阳性率为25.19%;从疑似副猪嗜血杆菌病患病猪的肺脏和腹膜中分离到2株革兰氏阴性细小杆菌,经生化试验和PCR鉴定,确定分离菌为副猪嗜血杆菌,分型结果为副猪嗜血杆菌血清5型(QH0804)和7型(QH0811)。结果表明,副猪嗜血杆菌病在4个地区一些猪场有不同程度的流行和发生。这一结果为该地区有效控制该病防制提供了依据。
