摘要
为了掌握福建省猪群猪流感H1亚型和H3亚型的感染情况,采用ELISA方法,对2009年与2010年采集的1 323份血清进行了猪流感H1和H3抗体测定。结果显示,2009年全省猪群感染猪流感H1和H3的抗体阳性率分别为50.5%和21.0%,其中规模猪场的阳性率分别为53.2%和23.0%,散养户的阳性率分别为21.0%和7.8%,屠宰场的阳性率分别为33.3%和9.1%;2010年全省规模猪群感染猪流感H1和H3的抗体阳性率分别为49.4%和18.4%,其中种猪的阳性率分别为56.1%和20.1%,商品猪的阳性率分别为39.2%和15.8%。结果表明,福建省猪群不论饲养规模大小还是不同猪群均在不同程度上感染了猪流感,且感染猪流感H1的抗体阳性率比H3的高。
The aim of this study was to obtain information of antibodies against swine influenza H1 and H3 subtypes in Fujian Province.A total of 1 323 serum samples from Fujian Province between 2009 and 2010 were analyzed by ELISA to detect antibodies against H1 and H3 subtype swine influenza virus（SIV）.Results showed that in 2009,50.5% serum samples tested was positive for H1 subtype SIV,21.0% serum samples tested was positive for H3 subtype SIV,and the seroprevalence was 53.2% and 23.0% on intensive pig farms,21.0% and 7.8% on small swine farms and 33.3% and 9.1% in abattoirs,respectively.In 2010,49.4% serum samples tested was positive for H1 subtype SIV,18.4% serum samples tested was po-sitive for H3 subtype SIV respectively.Prevalence in breeding pigs was 56.1% and 20.1%,respectively,and for commercial pigs,it was 39.2% and 15.8%.The results indicated that pigs in Fujian Province were infected with SIV with different degree,and the prevalence of H1 subtype was higher than that of H3 subtype.
