广西猪流感血清学调查

Serological investigation of swine influenza in Guangxi

采用血凝抑制试验对广西7个市30个猪场的2156份猪血清样品进行了猪流感病毒H1、H3亚型抗体的检测。结果显示,在被调查的30个猪场中,H1亚型抗体阳性率为96.67%,H3亚型抗体阳性率为86.67%,H1+H3亚型抗体阳性率为86.67%;在检测的2156份血清样品中,H1亚型抗体阳性率为29.04%,H3亚型抗体阳性率为31.54%,H1+H3亚型抗体阳性率为12.15%。表明在所调查的广西猪场中,猪流感病毒的感染较为普遍,大部分猪场都曾被H1、H3亚型感染。

Total 2156 swine blood samples were collected from 30 piggeries of seven cities in Guangxi, and H1 and H3 subtypes antibody of swine influenza virus of all samples were determined by hemagglutination inhibition test. Test results showed that in 30 piggeries, the positive rate of H1 and H3 subtypes antibody was 96.67% and 86.67%, respectively; and the positive rate of H1 ＋ H3 subtypes antibody was 86.67%. For 2156 samples, the positive rate of H1 and H3 subtypes antibody was 29.04 % and 31.54 %, respectively; and positive rate of H1 ＋ H3 subtype antibody was 12.15 %. It indicated that the infection of swine influenza virus was common in the invested piggeries in Guangxi, and most of piggeries were infected by H1 and H3 subtypes of swine influenza virus.
