Complete genome sequence of rabies virus CVS-24 from China

The entire genome of the mouse-adapted rabies virus strain CVS-24 (challenge virus standard 24), was sequenced. The overall length of the genome was 11,927 nucleotide (nt), comprising a leader sequence of 58 nt, a nucleoprotein (N) gene of 1353 nt, phosphoprotein (P) gene of 894 nt, a matrix protein (M) gene of 609 nt, a glycoprotein (G) gene of 1575 nt, an RNA-dependent RNA polymerase (RdRp, L) gene of 6384 nt and a trailer region of 70 nt. There was a TGAAAAAAA (TG₇) consensus sequence at the end of each gene, except the G gene which had an AGAAAAAAA sequence at the end, and the L/trailer region had the sequence CGAAAAAAA. Three were AACAYYYCT consensus start signals close to TG₇. The five cistrons were separated by intergenic regions (IGRS) of 2, 5, 5, 24 nt, respectively. Residue 333 of the mature G protein, which is considered to be associated with pathogenicity, was Ala in CVS-24. The topology of the phylogenetic trees generated using N protein sequences suggested that CVS-11 and CVS-N₂C have a close relationship to CVS-24.
