- ... Seven avian polyomaviruses (APVs) were isolated from seven psittacine birds of four species. Their whole genome sequences were genetically analyzed. Comparing with the sequence of BFDV1 strain, nucleotide substitutions in the sequences of seven APV isolates were found at 63 loci and a high level of conservation of amino acid sequence in each viral protein (VP1, VP2, VP3, VP4, and t/T antigen) was ...

- ... Avian polyomavirus disease and psittacine beak and feather disease (PBFD) are both contagious viral diseases in psittacine birds with similar clinical manifestations and characterized by abnormal feathers. To determine the prevalence of Aves polyomavirus 1 (APyV) and beak and feather disease virus (BFDV) in captive, exotic psittacine birds in Chile, feathers from 250 psittacine birds, representing ...
