Canine parvovirus (CPV) type 2 is the causative agent of acute hemorrhagic enteritis and high mortality in the affected dogs. Numerous studies have been done to understand the origin of the virus and to exhibit new variants and circulating strains. This report describes the detection and genomic characterization of CPV strains from indoor and outdoor dogs in Ankara, Turkey. Samples were sent to our laboratory due to clinical symptoms in puppies. We tested blood and swab samples to determine the presence of canine parvovirus (CPV) in three puppies and two adult dogs by reverse transcription-polymerase chain reaction (RT-PCR) using VP2 (capsid protein) region primers of canine parvoviruses. Following that, to provide molecular characterization data Maximum Likelihood (ML) method was used for phylogenetic analyses. Constructed phylogenetic trees from the aligned nucleotide sequences revealed that our CPV strains demonstrated high genetic similarities, with 100% identity match on nucleotide alignments with each other and classified in CPV-2b genotypes.They have placed on a monophyletic clade as a sister branch with CPV VAC S quantum with 98.9% nucleotide homology. Our findings suggest that CPV-2b is actual and frequently seen variant in Turkey and shows high similarities with other CPV variants and a bit less with FPVs in Turkey and around the world. CPV causes high mortality and morbidity in dogs and to develop effective vaccines for protection of dogs in Turkey where there are few numbers of studies that have been done, field strains should be isolated and characterised.

Canine kobuvirus (CaKVs) is a newly emerging virus detected in dogs in several countries. However, kobuvirus infection has not yet been described in domestic carnivores in Turkey. In this study, we tested blood and rectal swab samples to determine the presence of kobuvirus in a dog with clinical symptoms by reverse transcription-polymerase chain reaction (RT-PCR), using 3D (RNA polymerase) region primers of canine kobuviruses. To provide molecular characterization data, the Maximum Likelihood (ML) method was used for the phylogenetic analyses. The PCR product of the partial protein-coding region of the 3D protein gene from the rectal swab was amplified, purified, and sequenced. Phylogenetic analysis of amino acid sequences suggests that our CaKV strain was closely related to US-CaKVs,and placed on a monophyletic clade as a sister branch localized in the CaKV cluster. These results indicate that CaKV exists in dogs in Turkey. With a similarity of 94.2–96.1%, it is like other CaKVs. To our knowledge, this is the first report of CaKV infection of a dog by in Turkey. Further studies are needed to determine its role in dog gastrointestinal infections.
