目的分析2012—2016年新疆巴音郭楞蒙古自治州(简称巴州)禽流感外环境监测结果,为人感染高致病性禽流感的防控和预警提供参考依据。方法采集巴州各县(市)外环境标本,用实时荧光PCR法检测禽流感病毒FluA,阳性者进一步检测H5、H9和H7亚型。结果采集的680份外环境标本中,阳性106份、总阳性率15.59%,其中103份为H9;阳性率最高的标本为笼具表面擦拭标本(20.11%)、来自城乡活禽市场(26.33%)和家禽屠宰加工厂(26.09%)的标本,第一季度(28.96%)和2015年(25.93%)检测阳性率最高。结论巴州活禽市场和家禽屠宰加工厂存在禽流感病毒,活禽市场是人暴露禽流感病毒的高危场所,应采取综合性防控措施。
Objective To analyze the external environmental monitoring results of bird flu in Bayingolin Mongolian Autonomous Prefecture (Bazhou) in Xinjiang from 2012 to 2016, and to provide reference for prevention and control of human HPAI. Methods The peripheral environmental samples were collected from counties (cities) of Bazhou and FluA was detected by real-time fluorescence PCR. The positive samples were further tested for H5, H9 and H7 subtypes. Results Of the 680 samples collected from the external environment, 106 were positive, with a total positive rate of 15.59%, of which 103 were H9. The highest positive rate was found in surface wiped samples (20.11%) from the urban and rural live poultry market (26.33% ) And poultry slaughter and processing plants (26.09%), the highest positive rate was detected in the first quarter (28.96%) and 2015 (25.93%). Conclusion There are bird flu viruses in the live bovine poultry market and poultry slaughtering and processing plants in the state, and the live poultry market is a high-risk place for people to expose the bird flu virus. Comprehensive prevention and control measures should be taken.
