Phylogenetic tree for actin gene nuclotide sequences of T. vaginalis. The tree was generated using Maximum Likelihood method. Bootstrap test for 1000 replicates. Sequences from Kilifi isolates (n = 22) have accession numbers with the prefix “MF”, all other sequences were retreived from GenBank and are representative of the five actin genotypes. Scale-bar: 0.001 (1 substitution per 1000 nucleotides)
