Key result
Researchers identify natural co-infection of Pigeon aviadenovirus A and Pigeon circovirus in a Turkish flock.
Why the study?
Natural co-infection of Pigeon aviadenovirus A and Pigeon circovirus in pigeons had not been previously identified or molecularly characterized in Turkey.
Observational
Alerts veterinarians to co-infection risks in breeding pigeons; leaves open questions on pathogenicity and surveillance needs.
Pigeon aviadenovirus A and Pigeon circovirus are both viruses that can cause disease in pigeons. This study reports the identification of a natural co-infection of Pigeon aviadenovirus A and Pigeon circovirus in a breeding pigeon flock in central Anatolia, Turkey. Both viruses were isolated from pooled internal organs of pigeons using primary chicken embryo kidney cell cultures (CEKC) and specific pathogen free (SPF) embryonated chicken eggs. Both viruses were identified by PCR amplification followed by Sanger sequencing, while histopathological examination showed degenerated hepatocytes with basophilic intranuclear viral inclusions. The viruses have similar transmission characteristics and common clinical manifestations, but it is possible that coinfection may exacerabate disease. This is the first report of its kind in Turkey and is important for the protection against disease in pigeons.

Şahindokuyucu et al. (2020) conducted an observational in Young Pigeon Disease Syndrome (YPDS). Coinfection with Pigeon aviadenovirus A and Pigeon circovirus was evaluated on Identification and molecular characterization of viruses. Natural co-infection of Pigeon aviadenovirus A and Pigeon circovirus was identified and molecularly characterized in a breeding pigeon flock in Turkey.
