The genotype-specific primers for amplying and sequencing the genotype I & II Japanese encephalitis virus

Abstract

For constructing the high-throughput platform of sequencing the JEV whole genome, the two systems of multiplex primers for genotype I and III should be designed and used for detected the whole genome of genotype I and III JEV in the research. The two systems of JEV genotype-specific primers was designed based on the reference sequence of all the available genotype I and III JEV genome sequence on GenBank, then, they were used to amply and sequence the 121 JEV strains isolated in China contains 63 GIII JEV and 58 GI JEV. The self-designed genotype-specific primers for genotype I and genotype III JEV were 16 pairs and 17 pairs respectively, which were used for detecting the whole genome of 121 JEV. The average quality value for GI JEV is 40.037. The average quality value for GIII JEV is 40.857. The two systems of JEV genotype-specific primers could sequenced the genotype I and III JEV qualified and specific. It is the basis of the high throughput platform of sequencing the JEV whole genome.
