Fig. 2

Neighbour-Joining trees representing phylogenetic analysis of RSV genotypes isolated in Ghana between 2015 and 2016. The tree was constructed using the Neighbor-Joining method (Saitou N. and Nei 1987). “The optimal tree with the sum of branch length = 0.90679067 is shown. The percentage of replicate trees in which the associated taxa clustered together in the bootstrap test (1000 replicates) are shown next to the branches (Felsenstein 1985). The tree is drawn to scale, with branch lengths in the same units as those of the evolutionary distances used to infer the phylogenetic tree. The evolutionary distances were computed using the Maximum Composite Likelihood method (Tamura et al., 2004) and are in the units of the number of base substitutions per site. Sequences from this study are shown in bold green color and designated by the geographic location (GHA-PML), patient number and year of collection. The genotype clusters are indicated on the right side of figure. Only bootstrap values greater than 70% are displayed at the branch nodes
