title: Pathologic and serologic characterization of a variant of duck hepatitis type I virus.
abstract: A duck hepatitis virus (DHV), isolated from ducks on a farm in Virginia in 1963, was shown to be only partially related to DHV type I (DHV-I) in cross-neutralization and in cross-protection tests. The virus, named DHV-Ia, apparently is a serologic variant of DHV-I; both viruses are serologically distinct from DHV type III. Pathologic responses to DHV-Ia were similar to those described for DHV-I infection.
