Serum samples were collected from 385 wild boars between 2010 and 2013 to examine the seroprevalence of influenza A virus (IAV) in Japan. Antibodies against IAV were identified using a commercial kit in 13 wild boars (3.4%). To identify the serotypes, positive sera were examined by virus-neutralization test using representative serotypes and strains. Three wild boars in Yamaguchi and four in Tochigi showed the highest antibody titers against the pandemic H1N1 2009 virus and classical swine H1N1 virus strains, respectively. These data indicate that wild boars may have close contact with humans and domestic pigs and therefore that there is potential for IAVs to reassort in wild boars as they have been shown to do in pigs.
2010年至2013年间,从385头野猪身上采集血清样本,以检测日本甲型流感病毒(IAV)的血清阳性率。使用商用试剂盒在13头野猪(3.4%)中鉴定出了抗IAV抗体。为了鉴定血清型,使用代表性血清型和毒株通过病毒中和试验检测阳性血清。山口县的3头野猪和枥木县的4头野猪分别对2009年大流行H1N1病毒和经典猪H1N1病毒株表现出最高抗体滴度。这些数据表明,野猪可能与人类和家猪有密切接触,因此IAV有可能像在猪身上那样在野猪中发生重配。
