AbstractBackgroundDomestic cat hepadnaviruses (DCHs) have been described as a novel virus that can infect cats.ObjectiveThe aim of our study is the first identification and molecular characterizations of DCH infection in Turkish domestic cats.MethodsThe blood, organ and ascites fluid samples from 550 cats were randomly sampled. The presence of DCH nucleic acid was investigated by using both in the literature and newly designed primers.ResultsIt was found that the hepadnavirus positivity rate is 4% (22/550) in Türkiye. The full genomic characterization was performed on 13 of 22 samples, and others were characterized as nearly full genome. In this study, we highlight that whole blood samples should be also screened for DCH, not only serum samples as has frequently been done in other studies. DCH‐infected cats were also found positive (54.54%, 12/22) for Feline leukaemia virus infection. BLAST results revealed that Turkish DCHs have 86.32%–99.08% homology with strains in the GenBank database, enabling us to construct phylogenetic trees.ConclusionsAccording to this study's results, it is suggested that this infection should be added to veterinary diagnostic panels worldwide. Additionally, we suggest that our new synthesized primers for the amplification of X gene can also be used for diagnosis.
