Cloning and sequencing of columbid circovirus (coCV), a new circovirus from pigeons.
The complete nucleotide sequence of columbid circovirus (CoCV) isolated from pigeons is described. CoCV was amplified using a consensus primer PCR approach directed against conserved sequences within the rep genes of vertebrate circoviruses. The genome of CoCV is circular and 2037 nt in size. It displays 55% homology to the genome of psittacine beak and feather disease virus and is more distantly related (< 40% homology) to porcine circovirus type 1 and 2. Two major open reading frames were identified, encoding the replicase and the putative capsid protein of CoCV. A region similar to the origin of replication of other circoviruses was found: it encompasses a stem-loop structure with the nonamer 5'-TAGTATTAC, conserved in circo-, nano- and geminiviruses. Phylogenetic analyses suggest classification of CoCV as member of the genus Circovirus of the virus family Circoviridae.
