Complete or nearly full-length genome sequences (with incomplete 59 ends) were obtained for three positive samples using the sequencing strategy as described in the Methods section. For two of the samples that were positive only for RT-PCR screening with specific primers, only sequences for short segments of the viral genome were obtained. Additional viral genome sequencing on these samples was unsuccessful due to limited clinical materials available and possibly low viral titres. The complete genome of bat SaV strain TLC58 (Genbank accession number JN899075) is 7696 nt in length and has a genomic G+C content of 60.2 mol%. Both the length and G+C content of the bat SaV genome are significantly higher than that of other known SaVs (Table 2) . Each genome is predicted to contain 3 overlapping ORFs, comparable to the genome organization of SaVs in GI, GIV and GV ( Figure 1 ). The 59-UTR and the 39-UTR are 9 nt and 225 nt in length, respectively. The length of the 39-UTR is considerably longer than other SaVs ( Table 2 ). The two other nearly full-length bat SaV genomes were found to be highly similar to that of the complete bat SaV/TLC58 genome in nucleotide sequence and genome organization, and were not analysed separately.
