SNP-based phylogenetic tree. The figure shows a phylogenetic tree, rooted by the lymphogranuloma venereum (LGV)-strains, which presumably are most similar to the last common ancestor of the 79 C. trachomatis genomes depicted. The strains are divided into two biovars: the LGV- and urogenital strains. The urogenital strains are further split into two lineages T1 and T2. The T2 lineage is again split into the urogenital- and ocular strains
