Detection and Molecular Characterization of Kobuviruses: An Agent of Canine Viral Diarrhea.

ABSTRACT

Clarifying the etiology of diarrhea cases of unknown cause is important in the fight against enteric infections. In this study, we aimed to investigate the role of canine kobuvirus (CaKoV), in cases of diarrhea of unknown origin in dogs. A total 121 swab samples from dogs with diarrhea were collected. Molecular analyses of the samples were performed. For this purpose, after the sequence reaction, a phylogenetic tree was created, and bioinformatics analyses were performed. The prevalence rate of CaKoV in the sampled population was determined as 16.5% (20/121). The presence of parvovirus and coronavirus, which are common viral agents in CaKoV-positive dogs, was determined as 35% (7/20) and 10% (2/20), respectively. The rate of dogs with only CaKoV detected was 65% (13/20). Phylogenetic analysis of CaKoV strains clustered together closely related to reference strains. There are very limited studies on the role of CaKoV in the etiology of diarrhea cases of unknown cause in dogs around the world. So far, only one study has been done on CaKoV in Turkey. In this report which includes molecular characterization and epidemiological data on CaKoV determined the importance of CaKoV in cases of diarrhea of unknown origin. More comprehensive studies are needed to better understand the pathogenesis, epidemiology, and biology of CaKoV and to determine effective strategies to combat it.
