Surveillance surveys for reemergent trachoma in formerly endemic districts in Nepal From 2 to 10 years after mass drug administration cessation

This study analyzes whether the World Health Organization recommendation for surveillance surveys to be done 2 years after cessation of mass drug administration in districts formerly endemic for trachoma is sufficient to detect reemergence of disease

Comparison of platforms for testing antibody responses against the chlamydia trachomatis antigen Pgp3

This study  reports the sensitivity of MBA and ELISA using a set of specimens from individuals with ocular swab specimens positive by nucleic acid amplification tests (NAATs) and specificity of the MBA, ELISA, and LFA against a panel of pediatric specimens from nonendemic countries and evaluate the characteristics of the ELISA assay using different cutoffs and plate preparation approaches.
