Whole genome sequencing of ocular Chlamydia trachomatis in Amhara region, Ethiopia, an area with persistent hyperendemic trachoma.

This study will address the characteristics of the ocular chlamydia trachomatis population structures within Amhara, a setting which has experienced repeated rounds of antibiotic for trachoma, and whether those circulating populations are different than known sequenced strains.

ClearTrachoma: Evaluation of a novel molecular rapid diagnostic device for the detection of Chlamydia trachomatis in trachoma-endemic areas

The primary aim of this study is a first evaluation (384 samples) of the DjinniChip in ocular clinical samples in a trachoma-endemic region in-country, but initially in the controlled environment of a research laboratory setting. The second aim is to determine the DjinniChips resilience and usability by evaluating its performance with a concentration series of positive control swabs in various environmental conditions (hot, dry, dusty, humid).
