Fig. 1From: Chlamydia trachomatis isolated from cervicovaginal samples in Sapporo, Japan, reveals the circulation of genetically diverse strainsMid-rooted phylogenetic tree generated by the neighbor-joining method of the C. trachomatis ompA nucleotide sequences from 61 clinical strains isolated from Sapporo and 15 reference sequences available from the GenBank database. The sequence of C. muridarum was used as an outgroup. The clinical samples and their corresponding genotypes (number of samples, %) are represented by identical colors. The scale bar represents the number of nucleotide substitutions per siteBack to article page
