title: [Genomic characteristics and recombination of enterovirus 71 strains isolated in Henan Province between 2008 and 2010].
abstract: To reveal the genetic features and recombination of enterovirus 71 isolates between 2008 and 2010. A total of 5 enterovirus 71 isolates were sequenced completely and phylogenetic analysis and recombination were performed. Phylogenetic analysis based on VP1 regions revealed that the Henan enterovirus 71 between 2008 and 2010 belonged to C4a in subgenotype C4. Bootscan analyses and phylogenetic analysis based on the 5'UTR, P1, P2, P3 genomic regions revealed the recombinations between EV71 genotypes B and C at the 2A-2B junction, and between EV71 genotype B and CA16 strain G-10 at the 3B-3C junction. Henan enterovirus 71 isolates between 2008 and 2010 belonged to C4a in subgenotype C4 which was the predominant virus genotype circulating in mainland China since 2004, a combination of intratypic and intertypic recombination were found in EV71 subgenotype C4.
