<i>Chlamydia trachomatis</i> strains identified in this study.

<p>Only single nucleotide polymorphisms and their locations are shown. Reference strains are <i>C. trachomatis</i> HAR 13 (genovar A) (NC_007429) and <i>C. trachomatis</i> M33636 (genovar B). Letters in parenthesis represent the amino acid and any resulting change. Genotype B2 is identical to the reference strain. (VS, variable sequence. CS, conserved sequence.)</p

Comparative ocular <i>C. trachomatis</i> infection status (by Amplicor) before and two months after antibiotic treatment amongst all those tested at both time points.

<p>(+ infected, − not infected).</p

Clinical activity, infection (Amplicor) and genotypes by village and timepoint.

<p>For each village, ‘Examined’ is the number of people examined ‘TF/TI’ is the number of individuals (all ages) with active trachoma, and ‘CT+’ the number of those whose ocular swabs tested positive by Amplicor. The numbers bracketed after the genotype indicate the number of times it appeared: A2 (14) denotes 14 samples contained genotype A2.</p

Frequency of <i>C. trachomatis</i> strains present at baseline and 2 months, subdivided by site of collection. Numbers in parenthesis are %.
