遵义地区H3N2亚型犬流感病毒血清学调查

SEROLOGICAL SURVEY OF CANINE INFLUENZA VIRUS SUBTYPE H3N2 IN DOGS IN ZUNYI AREA

为了解遵义地区H3N2亚型犬流感病毒(Canine influenza virus,CIV)感染情况,本研究采用酶联免疫吸附试验对遵义市区及周边农村收集的320份血清样本进行了抗体检测。结果显示,遵义地区H3N2亚型CIV抗体整体阳性率为8.44%(27/320);农村田园犬抗体阳性率(9.24%)高于市区宠物犬(7.96%),但差异不具有显著统计学意义(P>0.05);雄性犬的抗体阳性率(8.79%)高于雌性(7.97%),差异不显著,不具有统计学意义(P>0.05);1~3岁的青年犬抗体阳性率最高(9.63%),其次为幼犬(8.62%),3岁以上犬最低(6.25%),差异不显著,不具有统计学意义(P>0.05)。结果表明,遵义地区存在H3N2亚型犬流感病毒感染,相关部门应加强防范。

To investigate the epidemiological status of Canine influenza virus H3 N2 infection in dogs in the Zunyi area,320 serum samples were collected from Zunyi urban area and surrounding countrysides and examined for serological antibodies by ELISA.The results showed that the serological positive rate of Canine influenza virus H3 N2 was 8.44%(27/320).The positive rate was higher in farm dogs(9.24%)than pet dogs(7.96%)but no significant difference(P>0.05).There were no significant difference(P>0.05)in positive rates between male and female dogs but the higher positive rate was seen in male dogs(8.79%)than female dogs(7.97%).In addition,the higher positive rate was noted in 1 to 3 year-old dogs(9.63%),followed by pups(8.62%),and over 3 years-old dogs(6.25%)but the difference was not statistically significant(P>0.05).These findings indicated the prevalence of Canine influenza virus H3 N2 infection in Zunyi area.
