贵州省牛传染性鼻气管炎、副结核病和新孢子虫病血清学调查

Serosurvey for Infections with Bovine herpesvirus type 1,Mycobacterium avium subsp.Paratuberculosis and Neospora caninumin Cattle in Guizhou Province

用酶联免疫吸附试验(ELISA)对采自贵州省内920份牛血清进行了牛疱疹病毒1型、副结核分支杆菌和犬新孢子虫抗体检测,结果显示,这3种病原体的血清抗体牛群阳性率分别为64.29%(18/28)、57.14%(16/28)和53.57%(15/28),血清样本总体阳性率分别为66.85%(615/920)、29.89%(275/920)和32.61%(300/920),调查表明,贵州省部分牛群存在不同程度的牛传染性鼻气管炎病毒、副结核分支杆菌或新孢子虫感染。
