    Abstract:
    OBJECTIVE: To analyze the genotype of newly isolated Japanese encephalitis viruses in Fujian province and the characteristics of amino acid sequence in the E gene. METHODS: PrM and E segments of newly isolated Japanese encephalitis viruses were amplified by RT-PCR, the PCR products were cloned into T vector for sequencing. Phylogenetic analysis was carried out by PHYLIP program. RESULTS: Newly isolated Japanese encephalitis viruses belonged to genotype III, the nucleotide and amino acid of E gene showed high homology to vaccine strain SA14-14-2, but had some difference in some domains. CONCLUSION: Newly isolated viruses in Fujian province belonged to Japanese encephalitis virus genotype III. E protein of the isolates showed some differences as compared with vaccine strains.
