Abstract:
We identified two novel circoviruses, HK02976 and HK00220, in oral swabs from bats. The size of their full genome was 2,010 nucleotides (nt). The full-genome sequence of our strains shared 96.1% nucleotide sequence identity with each other, and 39.9%-69.5% identity with bat-associated circoviruses (BatACVs)1-9. Based on the species demarcation threshold for viruses of the family Circoviridae, which is 80% genome-wide nucleotide sequence identity, we have tentatively named this group of viruses "bat-associated circovirus 10" (BatACV10).
