FIG 2.

Phylogenetic relationships of the MeV-N gene (left) and MeV-H gene (right) of measles virus genotype D4. The evolutionary history was inferred by using the maximum likelihood method based on the general time-reversible model. Measles virus genotype A (MVi/Maryland.USA/0.54) was used for rooting the tree. Evolutionary analyses were conducted with MEGA 6.06. Statistical support for grouping is shown as bootstrap values (1,000 replicated). Values of >80% are indicated at the deep node. The bar represents the genetic distance. The subgenotype classification is illustrated. Sequences were retrieved from the National Center for Biotechnology Information (NCBI) GenBank database and are named according to World Health Organization guidelines (Table 1).
