| Abstract: |
The novel domestic cat hepadnavirus (DCH), a member of the Hepadnaviridae, was first detected in Australia and has recently been identified in more countries. In this study, we explored the DCH genome using next-generation sequencing of a plasma sample from a cat with a fever of unknown cause. Nucleotide sequence analysis showed the virus to be relatively genetically distant from the first reported DCH in Australia, showing 89% homology. Then we conducted an epidemiological survey by PCR of plasma samples collected from 203 cats that visited a veterinary hospital for diagnosis and treatment. Two of the 203 surveyed cats a were positive for DCH. One of the two positive cases had elevated liver enzymes of unknown etiology, and the other had hepatocellular adenoma. Our study indicated that DCH infection was observed in domestic cats in the Tokyo area of Japan as well as other reported areas in the world. Further investigations are needed to define the clinical importance of DCH. [ABSTRACT FROM AUTHOR] |
