In the present study, we investigated the presence of unknown calicivirus diversity in bats by targeted RT-PCR screening. Novel SaV sequences were amplified from several faecal samples of the bat species Hipposideros pomona, and genome sequences were obtained for three strains of the bat SaV. Sequence analysis indicated that the novel virus possesses several genomic features atypical of SaVs, and phylogenetic analysis revealed that it descended from a lineage that had diverged early from other SaV.
