Outline of Final Research Achievements

In this study, to elucidate the frequency and distribution of non-primate hepacivirus among horses and dogs in Japan, serum samples from horses and dogs across Japan were screened for anti-nonstructural 3 protein antibodies using the Gaussia luciferase immunoprecipitation system assay. In the result, Japanese horses exhibit a high prevalence of NPHV, while no dogs showed seroprevalnece.
Serum samples from dogs and cats across Japan were also screened for antibodies against type A influenza viruses isolated from human, horse, and dogs, using hemagglutination inhibition assays and neutralization assays.In the result, 2.0% and 2.1% of the dogs and cats were positive for the subtype H1N1 human seasonal influenza virus, and 0.4 % of dogs were positive for the subtype H3N8 virus.
