Figure 2. . . Phylogenetic tree of enterovirus 71 viral protein 1 constructed by MEGA4 (www.megasoftware.net) with neighbor-joining method showing the relationship of 18 local sequences from 2010 and 2011 (triangles). Sequence names consist of the following information: the hospital at which the sample was obtained (HTD, Hospital for Tropical Diseases; CH1, Children’s Hospital 1; CH2, Children’s Hospital 2 (all from Ho Chi Minh City, Vietnam]); number in chronologic order/VNM for Vietnam/date (month-year). Reference genotypic sequences used in tree construction were obtained from GenBank. Detailed information about these sequences is available in reference (1).
