Abstract

The complete genome of a novel Circovirus isolated from an Australian raven (Corvus coronoides) with feather lesions similar to those that occur in psittacine beak and feather disease is reported. Degenerate polymerase chain reaction primers were designed to amplify and sequence novel Circovirus DNA from affected feathers. Sequence analysis indicated that the tentatively named raven circovirus (RaCV) was 1898 nucleotides in size with two major open reading frames synonymous with other avian circoviruses, ORF C1 and ORF V1, likely to encode a putative capsid protein (Cap) and replicase-associated protein (Rep), respectively. In common with other circoviruses was the conservation of several nucleotide structures and amino acid motifs implicated in virus replication. Comparison with other members of the Circoviridae demonstrated that RaCV shares the greatest sequence homology with canary circovirus (CaCV) and pigeon circovirus (PiCV) and was more distantly related to the beak and feather disease virus, goose circovirus, duck circovirus and the two porcine circoviruses, PCV1 and PCV2. Phylogenetic analysis of the genome and the putative Cap and Rep proteins provided further evidence of the close relationship of RaCV with CaCV and PiCV.
