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 %26lt;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 hepadnaviruses and contains ORFs for a preC/C, preS/S and polyprotein. Additionally, we identified an X-like ORF in the genome of PHBV. The full-genome data will be useful in developing screening tools for avihepadnaviruses in parrots.
