【摘要】：目的了解禽流感病毒在相关环境中的分布状况,为禽流感防控提供科学依据。方法在2015-2017年冬春季选择与禽类相关的4类场所,采集不同种类的环境标本用Real-time PCR方法进行禽流感病毒核酸检测,对监测结果进行分析。结果共采集禽类相关环境标本416份,A型禽流感病毒核酸阳性率31.97%(133/416),其中城乡活禽市场阳性率61.42%(121/197),屠宰加工厂阳性率54.55%(12/22),清洗禽类的污水阳性率74.51%(38/51),宰杀或摆放禽肉案板表面擦拭标本阳性率56.37%(31/55)。结论广元市冬春季节禽流感病毒在禽类相关环境中活跃存在,城乡活禽市场以及屠宰加工厂是主要污染场所,检出禽流感病毒亚型多,交叉污染现象较重。建议对活禽市场及屠宰加工厂加强管控,针对重点人群进行宣传提高防护意识,减少人感染禽流感病毒风险。
[Abstract]:Objective to investigate the distribution of avian influenza virus in related environment and provide scientific basis for bird flu prevention and control.Methods in the winter and spring of 2015-2017, four kinds of poultry related sites were selected, and different kinds of environmental samples were collected for detection of avian influenza virus nucleic acid by Real-time PCR method, and the results were analyzed.The positive rate of surface wiping specimens was 56.37%.Conclusion the avian influenza virus is active in poultry related environment in winter and spring season in Guangyuan City. The live poultry market and slaughtering and processing factory are the main polluted places in Guangyuan City. The avian influenza virus subtypes are detected and the cross-contamination phenomenon is serious.It is suggested to strengthen the control of live poultry market and slaughtering and processing factories, to raise the awareness of protection and to reduce the risk of human infection with avian influenza virus.
