Isolation and molecular identification of canine bufavirus: a novel enteric pathogen of dogs.
Canine bufavirus (CBuV) was initially detected in dogs with respiratory symptoms and later identified in fecal samples, suggesting that it could be an enteric pathogen. Several studies have shown that CBuV can be present in both healthy and diarrheic dogs, raising questions about whether CBuV is a primary enteric pathogen. In this study, we identified, isolated, and characterized CBuV from swab samples from dogs. A total of 119 samples from diarrheic dogs were analyzed by PCR, targeting a portion of the VP2 gene of CBuV. CBuV was detected in five dogs (4.2%). For virus isolation, CBuV-positive samples were inoculated onto an MDCK cell culture, and CPE was observed for one sample, which was tested for CBuV as well as other frequently detected enteric pathogens (canine distemper virus, canine parvovirus type 2, and canine coronavirus), but CBuV was the only virus detected. Phylogenetic analysis indicated that the CBuV isolates from this study are closely related to strains from China and India. The detection of CBuV in this study suggests that it might play a distinct role in canine diarrhea. Further studies are needed to investigate its genetic characteristics, epidemiology, and biological significance.
期刊介绍:
Archives of Virology publishes original contributions from all branches of research on viruses, virus-like agents, and virus infections of humans, animals, plants, insects, and bacteria. Coverage spans a broad spectrum of topics, from descriptions of newly discovered viruses, to studies of virus structure, composition, and genetics, to studies of virus interactions with host cells, organisms and populations. Studies employ molecular biologic, molecular genetics, and current immunologic and epidemiologic approaches. Contents include studies on the molecular pathogenesis, pathophysiology, and genetics of virus infections in individual hosts, and studies on the molecular epidemiology of virus infections in populations. Also included are studies involving applied research such as diagnostic technology development, monoclonal antibody panel development, vaccine development, and antiviral drug development.Archives of Virology wishes to publish obituaries of recently deceased well-known virologists and leading figures in virology.
