Table 3 Polymorphic loci among strains that infect the same biological niche

The represented loci may hypothetically be involved in the pathogenesis of ocular trachoma, genital infections or LGV disease, but do not contribute to the adaptive evolution of strains to each correspondent biological niche (Figure 4). Polymorphism was defined as >4% nucleotide differences or >40 SNPs (for genes >3 Kb).
