Background: Circoviruses are small, non-enveloped, single stranded DNA viruses. There is scarce information about these agents in non-psittacine birds. Aim: It is tried 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 PCR for the detection of rep gene of circoviruses was applied. Result: Two different types of circoviruses were detected in two pigeon samples (2/11, 18.2%). One of the detected circovirus 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. Conclusion: In addition to the molecular diagnosis of a pigeon circovirus, this is the first report of the detection of canary circovirus in a pigeon. The possible hypotheses of such circumstance are discussed.
