Figures & Tables

Neighbor-joining tree representing evolutionary relatedness of full-length ompA sequences from 19 C. trachomatis reference strains and 14 clinical isolates of serovars D, E, F, G, H, and K from Thai women and girls. All clinicals represent the isolates before antibiotic treatment. The length of branch is proportional to the distance between sequences, and number at node is the percent bootstrap confidence for clustering of strains.

Neighbor-joining tree representing evolutionary relatedness of full-length trpA sequences from 19 C. trachomatis reference strains and 14 clinical isolates from Thai women and girls (serovars D, E, F, G, H and K). All clinical isolates represent the first collected isolates prior to antibiotic treatment. Length of branch is proportional to distance between sequences, and number at node is the percent bootstrap confidence for clustering of strains.

Three-dimensional structures of non-active TrpA (A) and active TrpA–TrpB complex (B), with the nonsynonymous amino acid polymorphisms in respected to the clinical D/L11bf and H/U20bf (Q37R/R37Q, A115V/V115A, and C177Y). Clinical polymorphisms were represented in gray with atomic bonds, critical TrpA and TrpB residues (including C177Y) in gray, and TrpB COMM domain in white.
