Fig. 3

Phylogenetic tree of the C. trachomatis ompA D genotype sequences from nine clinical strains isolated in this study, 12 clinical strains from Sapporo from a previous study (4), four reference strains, and other clinical strains from the USA, Russia, Sweden, Thailand, and India. The strains isolated in this study are indicated by their identification number whereas other strains are indicated by their GenBank accession numbers. Strains represented in red indicate overall Sapporo D genotypes, whereas strains represented in fuchsia indicate Sapporo D1 genetic variants. The neighbor-joining method with a bootstrap value of 1000 replicates was used to construct the phylogenetic tree. The scale bar represents the number of nucleotide substitutions per site
