Figure 8. Genetic diversity of measles virus strains identified in Georgia, 2013–2018. Genotype D8 cluster of a phylogenetic tree is based on 450 nt of the measles virus nucleoprotein gene. The Kimura 2-parameter model and the neighbor-joining method in MEGA7 (14) were used, and only bootstrap values >70 are shown. The closest matches of the Georgia sequence variants identified by BLAST (https://blast.ncbi.nlm.nih.gov/Blast.cgi) are marked with a diamond; named strains of genotype D8 are marked with a square. For identical sequences, only the oldest and the most recent strains found in a certain location in a certain year are shown. The total number of sequences identified in each cluster are included in parentheses. Year of virus detection is indicated by colored circles: black for 2013, red for 2014, green for 2015, yellow for 2016, blue for 2017, pink for 2018. Scale bar indicates genetic distance, calculated based on the Kimura 2-parameter model, measured in nucleotide substitutions per site.
