Molecular phylogenetic analysis by Maximum Likelihood method between Kenyan WNV bird strains (bold) and known WNV strains in the GenBank. The evolutionary history was inferred by using the Maximum Likelihood method based on the Tajima-Nei model [35]. The tree with the highest log likelihood (−1866.0300) is shown. The percentage of trees in which the associated taxa clustered together is shown next to the branches. Initial tree(s) for the heuristic search were obtained automatically by applying Neighbor-Join and BioNJ algorithms to a matrix of pairwise distances estimated using the Maximum Composite Likelihood (MCL) approach, and then selecting the topology with superior log likelihood value. Evolutionary analyses were conducted in MEGA6 [22]
