摘要
2006—2008年对贵州省内610份奶牛血清进行检测,其中有116份血清为乙型肝炎表面抗原(HBsAg)阳性,平均阳性率19%;534份牛血清样品中,检出奶牛传染性鼻气管炎阳性血清29份,阳性率为5.4%,而运用血清补体结合反应(CFT)检测奶牛传染性胸膜肺炎,均为阴性。将HBsAg、HBeAg双阳性奶牛肝组织做电镜观察,发现肝组织中有密集的HBV颗粒。结果表明,贵州省奶牛可能存在乙型肝炎、传染性鼻气管炎的感染,应当引起奶牛养殖者的高度重视。
From 2006 to 2008,116 hepatitis B positive serums were detected in 610 dairy cow serums in Guizhou province,the mean positive ratio of HBsAg was 19%（116/610）.29 infectious bovine rhinotracheitis positive serums were detected by neutralization test in 534 dairy cow serums,the positive ratio was 5.4%（29/534）.The antibody of dairy cow contagious pleuropneumonia were negative in 534 dairy cow serums by CFT.HBV particles were observed by electron microscopic observation.The results indicated that dairy cow type B hepatitis and infectious rhinotracheitis existed probably in Guizhou province.The breeding cow industry should pay close attention to dairy cow type B hepatitis and infectious rhinotracheitis.
