Epidemiological Survey and Analysis on Avian Inlfuenza Virus inLiveBird Markets in a City of Eastern China during 2014-2016
摘要
Abstract
In order to recognize the contamination situation of avian influenza virus(AIV)in live bird markets (LBMs)in a city of eastern China,an epidemiological investigation on AIV towards poultry in LBMs was carried out during 2014—2016. The results showed that there was a wide range of AIV contamination in LBMs,and 94.12%of the investigated LBMs were infected by AIV. Among them the infection rate of H9N2 virus was relatively high(an overall positive rate of 22.66%),and at the farm level the positive rate was 94.12%.The infection rate of H7N9 virus has presented a rise-and-fall process,it reached the peak in the first half year of 2015,then decreased obviously. The isolation rate of H7N9 subtype in retail markets was significantly higher than that in wholesale markets. In addition, the H5 subtype highly pathogenic avian influenza virus wasn’t detected during this investigation. In a conclusion, theses data will provide technical supports for deeply understanding the contamination of AIV in LBMs,as well as establishing appropriate prevention and control measures for AI.关键词
