Canine distemper virus infection among wildlife before and after theepidemic

[摘要] References(28)Cited-By(3)In 2007�?2008, a canine distemper virus (CDV) epidemic occurred among wild animals inWakayama Prefecture, Japan, and many mammals, including the wild boar and deer, wereinfected. In this study, CDV prevalence among wild animals was surveyed before and afterthe epidemic. At first, an enzyme-linked immunosorbent assay (ELISA) with horseradishperoxidase-conjugated protein A/G was established to detect CDV antibodies in manymammalian species. This established ELISA was available for testing dogs, raccoons andraccoon dogs as well as virus-neutralization test. Next, a serological survey of wildmammalians was conducted, and it was indicated that many wild mammalians, particularlyraccoons, were infected with CDV during the epidemic, but few were infected before andafter the epidemic. On the other hand, many raccoon dogs died during the epidemic, but CDVremained prevalent in the remaining population, and a small epidemic occurred in raccoondogs in 2012�?2013. These results indicated that the epidemic of 2007�?2008 may have beenintensified by transmission to raccoons.
