Abstract
BACKGROUND: Circoviruses are small, non-enveloped, single stranded DNA viruses. There is scarce information about these agents in non-psittacine birds. AIMS: It is attempted to detect and characterize circoviruses in non-psittacine birds. METHODS: Forty-five samples were collected from different non-psittacine species belonging to seven avian orders. A nested polymerase chain reaction (nested-PCR) for the detection of rep gene of circoviruses was applied. RESULTS: Two different types of circoviruses were detected in two pigeon samples (2/11, 18.2%). One of the detected circoviruses was placed in clade A next to a polish strain based on phylogenetic analysis. Interestingly, the other detected circovirus was closely related to canary circoviruses (CaCVs). CONCLUSION: In addition to the molecular diagnosis of a pigeon circovirus (PiCV), this is the first report of the detection of CaCv in a pigeon. The possible hypotheses of such circumstance are discussed.
