Distribution of the antibody to influenza C virus in dogs and pigs in Yamagata Prefecture, Japan.

abstract：:Twelve monoclonal antibodies against Negishi virus were obtained and characterized by hemagglutination inhibition (HI) and neutralization (NT) tests using five flaviviruses isolated in the pan-Pacific region. The reaction pattern of the antibodies showed that Negishi virus was most closely related to Langat virus, fol...
