Molecular characterisation of an avihepadnavirus isolated from Psittacula krameri (ring-necked parrot).Avihepadnaviruses have been documented previously in ducks, herons, geese, storks and cranes. Here, we describe the full genome of a new avihepadnavirus isolated from Psittacula krameri (ring-necked parrot) in Poland. The parrot hepatitis B virus (PHBV) genome (3042 bp) shares <76% sequence identity with other avihepadnavirus isolates and is phylogenetically most closely related to heron and stork hepatitis B viruses isolates. PHBV has a genome organization similar to that of other hepadnaviruse ...201122183110
avian polyomavirus genome sequences recovered from parrots in captive breeding facilities in poland.eight genomes of avian polyomaviruses (apvs) were recovered and sequenced from deceased psittacula eupatria, psittacula krameri, and melopsittacus undulatus from various breeding facilities in poland. of these apv-positive samples, six had previously tested positive for beak and feather disease virus (bfdv) and/or parrot hepatitis b virus (phbv).201526404592
