摘要
为了解广东省规模化猪场H1和H3亚型猪流感病毒的流行情况,采用ELISA检测方法对采集于广东省14个市的28个规模化猪场的1 015份猪血清进行H1亚型和H3亚型猪流感病毒的抗体检测。结果表明,H1亚型抗体总阳性率为40.9%,猪场阳性率高达92.9%(26/28);H3亚型抗体总阳性率为16.8%,猪场阳性率为78.6%(22/28)。其中粤西和珠三角地区H1亚型抗体阳性率分别为49.6%和45.4%,H3亚型抗体阳性率分别为14%和20.8%;而粤东和粤北地区H1亚型抗体阳性率分别为2.7%和12%,H3亚型抗体阳性率分别为6.3%和0。说明在广东省被调查的猪场中,H1和H3猪流感病毒的感染较为普遍,其中H1型感染率高于H3型。广东省SIV流行情况存在明显的地域性差异。
In order to understand the prevalence situation of H1 and H3 subtypes of swine influenza viruses（SIV） in current swine farms in Guangdong province,1 015 swine serum samplers were collected from 28 swine farms of 14 cities in Guangdong,and antibodies against H1 and H3 subtypes of SIV were determined by ELISA.The results showed that,H1 subtype antibody total positive rate was 40.9%,and positive rate for swine farms was 92.9%（26/28）;H3 subtype antibody total positive rate was 16.8%,and the positive rate for swine farms was 78.6%（22/28）.In western region and Pearl River Delta region of Guangdong,H1 subtype antibody positive rates were 49.6% and 15.4%,and H3 subtype antibody positive rates were 14.0% and 20.8% respectively,while in eastern and northern regions of Guangdong,H1 subtype antibody positive rates were 2.7% and 12.0% and H3 subtype antibody positive rates were 14.0% and 20.8% respectively.The results indicated that the infections with H1 and H3 subtypes of SIV were very common in Guangdong＇s swine farms,and H1-type infection rate was higher than that of H3-type.There were obvious regional differences in SIV prevalence situation in Guangdong province.
