Abstract

Hantavirus genome sequences were recovered from lung tissues of Chinese white-bellied rats (Niviventer confucianus) captured in Yunnan province, China. Pairwise comparison of the nucleotide and deduced amino acid sequences of the entire S and partial M and L segments indicated that the newly discovered virus strain, which was designated as strain YN509, was very different from other rodent-borne hantaviruses. Phylogenetic analysis showed that the new strain fit into a clade containing Da Bie Shan virus (DBSV) (also carried by N. confucianus), which is mainly found in Anhui Province in mainland China. Strain YN509 appears to be in a sister taxa of the DBSV group described previously. These data suggest that strain YN509 is a new subtype of DBSV, which appears to be widely distributed in China with a higher genetic diversity than expected. © 2010 Elsevier B.V.
