Figure 1. Phylogenetic analysis of E-7 (A) and CV-B5 (B) based on VP1 sequences.

Figure 1

The phylogenetic trees were constructed using Mega, version 4.0, using the NJ method based on 712-nt (positions 2611 to 3322 on strain Wallace) and 685-nt (positions 2611 to 3295 on strain Faulkner) partial VP1 sequences of E-7 and CV-B5, respectively. ●, global reference strains. □, Shandong strains previously isolated from AFP cases or sewage. ▲ in B, CV-B5 strains from two aseptic meningitis outbreaks in Shandong in 2005 and 2009, respectively. The rest are sequences from environmental strains in this study.
