【摘要】：为了解贵州省H7亚型禽流感感染情况,采用HI试验对全省9个地区家禽血清样本进行血清抗体检测,PT-PCR方法对家禽咽-肛拭子、养禽场环境样本和野鸟粪便进行病原核酸检测。结果显示:在1570份家禽血清样本中,H7亚型禽流感血清抗体阳性率为0.45%(7/1570);在350份家禽咽-肛拭子和310份养殖场环境样本中,均未检测出H7亚型禽流感病毒核酸;在160份野鸟粪便中,有1份为H7亚型禽流感病毒核酸阳性,阳性率为0.63%(1/160)。试验提示,在贵州省养禽场中不存在H7亚型禽流感感染,但迁徙野禽中可能存在H7亚型禽流感隐性感染,应当引起重视。

PT-PCR method was used to detect pathogenic nucleic acid in throat and anus swabs of poultry, environmental samples of poultry farms and feces of wild birds. The results showed that the positive rate of H7 avian influenza antibody was 0.45% (7 鈮，
