Fig. 2From: Identification of a new recombinant strain of echovirus 33 from children with hand, foot, and mouth disease complicated by meningitis in Yunnan, ChinaPhylogenetic trees based on the P1, P2, and P3 coding sequences of 383 EV-B strains. The phylogenetic relationships among the two E-33 isolates and 381 EV-B strains available in the GenBank database were analyzed using the MEGA 6.06 program. Numbers at the nodes represent bootstrap values supported for that node (1000 bootstrap replicates). Only high bootstrap values (>75%) are shown. The scale bars indicate the genetic distance. â–² strains were isolated in this study and the red colour indicates the other E-33 strainsBack to article page
