Isolation and full-length genome analysis of mosquito-borne Manzanilla virus from Yunnan Province, China

BACKGROUND: There have been four strains on Manzanilla virus (MANV) identified to date. Here, we identify a novel MANV strain (DHL10M107) isolated from Culex tritaeniorhynchus Giles mosquitoes from Ruili city, Dehong prefecture, Yunnan Province, in the People’s Republic of China. RESULTS: The DHL10M107 L, M and S genes were sequenced at the nucleotide and deduced amino acid levels. The L, M and S gene sequences of DHL10M107 clustered with the MANV strains VN04-2108, TRVL3587, SA An 4165, and AV 782. DHL10M107 was most closely related to VN04-2108. Nucleotide homology ranged between 96 and 99% between DHL10M107 and VN04-2108. In terms of amino acid homology, all of the amino acid differences were in the L (96.3% homologous) and M (97.7% homologous) fragments. CONCLUSIONS: DHL10M107 is likely a MANV isolated from mosquitos in the Yunnan Province. This is the first reported isolation of MANV in mainland China.
