Phylogenetic characteristics and recombination analysis of echovirus 5 associated with severe acute respiratory infection in China.

ABSTRACT: Echovirus 5 (E5) belongs to the enterovirus B (EV-B) species, which is one of the pathogens causing respiratory diseases. Only two whole genome sequences (WGSs) of E5 are available in GenBank, and few studies on E5 have been reported worldwide. In this study, human rhabdomyosarcoma (RD) cells were used to isolate E5 from respiratory samples associated with severe acute respiratory infection (SARI). The nucleotide sequence of the VP1 region and the WGSs of two E5 strains were sequenced using Sanger sequencing and high-throughput sequencing technology, respectively. Together with 31 E5 VP1 sequences and 2 WGSs downloaded from GenBank, a total of 33 complete VP1 sequences and 4 WGSs were used for genetic characterization and evolutionary analysis. Phylogenetic analysis revealed five genotypes
