【摘要】：目的分析江西省外环境禽流感病毒流行特点,为禽流感防控工作提供参考。方法 2015-2016年,随机抽取江西省15个省级禽流感监测点进行外环境采样监测,采用RT-PCR法对标本进行A型、H5、H7、H9亚型流感病毒核酸检测。结果 2015-2016年共收集15个监测点环境样本3 057份,其中H5、H7、H9和A型未分型所占比例分别为32.88%、5.58%、66.47%和19.77%。四个季度禽流感病毒阳性率由高到低依次为:第四季度(54.60%)、第一季度(52.57%)、第二季度(47.93%)和第三季度(47.70%)。各类型场所中,活禽批发市场病毒阳性率最高(81.67%),其次为城乡活禽市场(55.14%)。禽类饮水标本病毒阳性率最高(63.48%)。乐平市监测点阳性率最高(87.62%),而余江县最低(15.71%)。结论江西省外环境禽流感病毒阳性率较高,主要亚型为H5、H9,冬春季节为重要防控季节,活禽批发市场和城乡活禽市场是重点监控场所。
[Abstract]:Objective to analyze the epidemic characteristics of avian influenza virus in the environment of Jiangxi Province, and to provide reference for the prevention and control of avian influenza. Methods from 2015 to 2016, 15 provincial avian influenza surveillance sites in Jiangxi Province were randomly selected for external environment sampling and RT-PCR method was used to detect the nucleic acid of influenza virus type A H5, H7 and H9. Results A total of 3 057 environmental samples were collected from 15 monitoring sites in 2015-2016. The proportions of H5, H7, H9 and type A without typing were 32.88 and 5.585.58%, 66.47% and 19.77%, respectively. The positive rate of avian influenza virus in the fourth quarter is 54.60, the first quarter is 52.57, the second quarter is 47.933) and the third quarter is 47.70. In all kinds of places, the positive rate of live poultry virus was the highest in wholesale market of live poultry (81.67%), followed by 55.14% in urban and rural markets. The positive rate of virus in drinking water samples of poultry was the highest (63.48%). The highest positive rate was 87.62 in Leping and the lowest was 15.71 in Yujiang. Conclusion the positive rate of avian influenza virus in the environment of Jiangxi Province is high, the main subtype is H5H9, the winter and spring season is an important control season, the live poultry wholesale market and the urban and rural live poultry market are the key monitoring sites.
