title: [Complete genome sequence of Coxsackievirus B5 (CVB5/09) strain isolated in China and its phylogenetic analysis].
abstract: An outbreak of hand foot and mouth disease occurred in Shang dong, China in 2009. Almost 20% of patient's swabs was positive for Coxsackie virus B5 (CVB5) identified by RT-PCR and sequencing. It was suggested that CVB5 may be another important pathogen for HFMD. Fifteen pairs of overlapping primers were designed and the genome sequence was sequenced. The genome of CVB5 was 7 399 nt in length, coding for 2 185aa. The genome displayed 80.6%-85.3% nucleotide sequence identity and 96.1%-96.9% amino acid sequence identity with another three CVB5 respectively. Phylogenetic analysis showed that different segment of genome underwent a distinct evolutionary and selective pressure. Simplot analysis displayed no evident recombination between genome of CVB5 and other HEV B viruses. The complete and characterized genome of CVB5/09 provides further insight into the genetics of CVB5 and other HEV B viruses, aiding in the surveillance and control of HFMD.
