Abstract: | Avian bornaviruses (ABVs) were recently discovered as the causative agents of proventricular dilatation
disease (PDD). Although molecular epidemiological studies revealed that ABVs exist in Japan, no Japanese
isolate has been reported thus far. In this study, we isolated four strains of Psittaciform 1
bornavirus from psittacine birds affected by PDD using QT6 quail cells. To our knowledge, this is
the first report to isolate ABVs in Japan and to show that QT6 cells are available for ABV isolation. These
isolates and QT6 cells would be powerful tools for elucidating the fundamental biology and pathogenicity of
ABVs. |
