Plain-English summary
A flock of breeding pigeons in Turkey experienced severe health issues, including vomiting, diarrhea, loss of appetite, and sudden death, due to a co-infection of two viruses: Pigeon aviadenovirus A and Pigeon circovirus. These viruses can weaken the immune system and lead to a condition known as Young Pigeon Disease Syndrome (YPDS). The researchers confirmed the presence of both viruses through laboratory tests and found significant liver damage in the affected birds. This discovery highlights the importance of monitoring and protecting pigeons from these viral infections to prevent serious outbreaks in the future.

Abstract
Pigeon aviadenovirus A and Pigeon circovirus are both DNA viruses, infect and cause severe clinical diseases in pigeons. These viruses are associated with an immunosuppression syndrome similar to 'Young Pigeon Disease Syndrome' (YPDS). This study reports the identification of a natural co-infection, with severe clinical signs (crop vomiting, watery diarrhoea, anorexia and sudden death) of Pigeon aviadenovirus A and Pigeon circovirus in a breeding pigeon flock in Central Anatolia, Turkey. Both viruses were isolated from pigeons pooled internal organs using primary chicken embryo kidney cell cultures (CEKC) and specific pathogen-free (SPF) embryonated chicken eggs. Also, both viruses were identified by PCR amplification followed by Sanger sequencing whereas histopathological examination showed degenerated hepatocytes with basophilic intranuclear viral inclusions. As known, both viruses typically have similar transmission characteristics and common clinical manifestations; however, co-infection may exacerbate the disease with devastating outcomes. This is the first report of its kind in Turkey for those viruses and is essential for the protection against these kinds of infections in pigeons.
