[Characterization of rabies virus phosphoprotein in high prevalence provinces of China]

Characterization of rabies virus phosphoprotein through analyzation of genetic variations about rabies virus phosphoproteins in high-incidence regions in China.The nucleotide sequence of the P gene of Guangxi, Guizhou and Hunan provinces positive sample's were sequenced, and the P region's similarity and phylogenetic analyses were completed by using softer wares.The similarity of P region's nucleotide sequence is 82.1%-100%, while, the similarity of amino acid sequence is 87.5%-100%. A little variation in phosphoprotein cannot influence its biological functions.All rabies viruses isolated from Guangxi, Guizhou and Hunan provinces belong to genotype 1 and share same phylogenesis and same genome characteristic; Virus distribution presents unique Characterization; Some virus isolates from Hunan province and Thailand may come from the same virus.
