Abstract

Abstract The DNA of a virus isolated from fledgling budgerigars, designated BFDV, was cloned and analyzed with regard to its relationship to the polyomavirus subgroup of the papovavirus family. Under relaxed conditions, the DNA of BFDV cross-hybridized with the DNAs of members of the polyomavirus subgroup, such as the mouse polyomavirus, the monkey viruses simian virus 40, stump-tailed macaque virus, and lymphotropic papovavirus, and the human viruses JCV and BKV. Under stringent conditions, however, no homologies could be detected. Furthermore, BFDV propagated in chicken embryo cells was antigenically related relthe capsid antigen(s) of the other polyomaviruses. The virus was able to transform hamster embryo cells in vitro which is a typical feature of polyomaviruses. These data clearly indicate that BFDV is a new distinct member of the polyomavirus genus representing the first nonmammalian polyomavirus.
