摘要
猪流感是一种人畜共患传染病,猪流感病毒(Swine influenza virus,SIV)在全世界各国的猪群中普遍存在。为了解山东省猪群中SIV的感染情况,2016年6月至2017年12月在山东省各地共采集7000份血清,采用HI抗体检测方法,分别用类禽型猪H1N1(EA H1N1)、2009甲型H1N1(2009/H1N1)和H3N2亚型抗原为标准抗原进行检测。结果显示,SIV抗体总阳性率为63.79%,其中EA H1N1抗体阳性率为56.31%,2009/H1N1抗体阳性率为24.61%,H3N2亚型抗体阳性率为1.61%。本研究结果表明2016~2017年山东省SIV感染比较普遍,类禽型猪H1N1抗体阳性率最高,2009甲型H1N1,H3N2抗体阳性率较低。
Swine influenza is an important zoonosis.Serological investigation is a useful method to learn the infection status due to the unavailability of effective vaccine.In this study,the epidemic status of swine influenza virus among pig population during 2016-2017 in Shandong province were investigated by hemagglutination inhibition assay.A total of 7000 serum samples were collected from most areas of Shandong province and tested using antigen preparations of avian H1N1(EA H1N1),2009H1N1(2009/H1N1)and H3N2.The results showed overall 63.79%positive rate.The positive percentages of H1N1(EA H1N1),2009 H1N1(2009/H1N1)and H3N2 antibodies were 56.31%,24.61%and 1.61%,respectively.The survey indicated that in the past two years,EA H1N1 subtype was predominant among pig population,which provide useful information on vaccine development and control.
