摘要
为了解规模化肉鸡场鼻气管鸟杆菌(Ornithobacteriumrhinotracheale, ORT)、禽呼肠孤病毒(Avian Reovirus, ARV)和禽偏肺病毒(Avian metapneumovirus, a MPV)的感染情况,用ELISA方法对2017年冬季和2018年春季自河北唐山地区动态采集的肉鸡血清进行了ORT、 ARV和aMPV抗体检测。结果表明:唐山地区规模化肉鸡场在冬、春两季均存在ORT、ARV和aMPV这3种病原的混合感染,尽管冬、春两季肉鸡群3种抗体水平存在动态差异,但两季均各出现了2次ORT感染、2次ARV感染和1次aMPV感染。应引起相关部门和人员高度重视。
