摘要/Abstract

摘要： 为了解中国部分省市规模化猪场H1和H3亚型猪流感病毒的流行情况,采用血凝抑制试验对采集于广东、湖南、河南省12个市县28个规模化猪场的799份血清进行H1和H3亚型猪流感病毒的抗体检测。结果表明,H1亚型抗体阳性率在0~83.33%之间,猪抗体总阳性率为46.18%(369/799),猪场阳性率为89.29%(25/28)。H3亚型抗体阳性率在0~100.00%之间,猪抗体总阳性率为61.33%(490/799),猪场阳性率为85.71%(24/28)。广东、湖南和河南地区H1亚型抗体阳性率分别为48.91%、40.26%和50.67%,H3亚型抗体阳性率分别为58.55%、70.78%和78.67%。在被调查的上述3个地区的猪群中,H1和H3亚型猪流感病毒的感染较为普遍,其中H3亚型感染率高于H1亚型,且各地区猪流感病毒的流行情况存在地域性差异。

Abstract: To survey the epidemics of H1, H3 subtypes of swine influenza virus in some scale pig farms in some provinces, 799 swine serum samples were collected from 28 factory pig farms on 12 cities in Guangdong, Hunan and Henan provinces. The antibodies against H1 and H3 subtypes of SIV were determined by HI assay.The results showed that the positive rate of H1 subtype antibody of pigs was between 0~83.33%, the average positive rate of pigs was 46.18% (369/799) and the positive rate of pig farms was 89.29% (25/28).The positive rate of H3 subtype antibody of pigs was between 0~100%, the average positive rate of pigs was 61.33% (490/799) and the positive rate of pig farms was 85.71% (24/28). The average positive rate of H1 subtype antibody of pigs of Guangdong, Hunan and Henan provinces respectively was 48.91%, 40.26% and 50.67%, the rate of H3 subtype antibody was 58.55%, 70.78% and 78.67%.It showed that the infection of H1 and H3 subtypes of swine influenza virus was widespread in the surveyed pigs of the 3 above regions.The infection rate of H3 subtype was higher than H1 subtype.The epidemics of swine influenza varied in different region.
