摘要 目的:为适时掌握平凉红牛规模养殖场口蹄疫O型和A型免疫抗体水平及野毒感染情况。方法:选取平凉地区某红牛规模养殖场,在5月、8月、11月份随机采集牛血清30份,OP液30份,采用液相阻断ELSIA方法检测血清中免疫抗体,采用实时荧光定量PCR方法检测血清和OP液中口蹄疫病毒核酸。结果:该养牛场2019年5月、8月、11月份牛O型和A型口蹄疫免疫抗体合格率分别为93.3%、60%、90%和63.3%、46.6%、66.6%;5月、8月、11月份该养牛场牛口蹄疫病毒核酸检测结果均为阴性。结论:平凉红牛规模养殖场5月、11月份O型口蹄疫免疫抗体水平高于70%,8月份低于70%,而5月、8月、11月份A型口蹄疫免疫抗体水平均低于70%,A型口蹄疫免疫效果较差,达不到保护效果,应重新调整免疫程序加强免疫;2019年3次监测该场无口蹄疫野毒感染。本研究为平凉红牛规模养殖场口蹄疫免疫程序的制定和防控工作提供了依据。
