Molecular phylogenetic analysis of virus isolates, Ouham Prefecture, Central African Republic, 2011. The neighbor-joining method was used for reconstructing the phylogenetic tree of the N gene sequences of reference B2 and B3 measles virus strains and new sequences from the Central African Republic identified in this study (surrounded). The percentages of replicate trees in which the associated virus isolates clustered together in the bootstrap test (1000 replicates) are shown next to the branches.
