Molecular and Epidemiologic Analysis of Dengue Virus Isolates from Somalia
Figure 2. Phylogenetic tree of the dengue-2 viruses, including Somalia 1993 virus isolates, using nucleotide sequence from position 639 to 1,233 of the envelope protein gene. This strict consensus tree was constructed by the following programs of the PHYLIP 3.5 package: SEQBOOT, DNAPARS, CONSENSUS, and DRAWGRAM. Strain ID is listed first, followed by abbreviation for country of isolation, and the last two digits of the year of isolation.
