CT694 and pgp3 as Serological Tools for Monitoring Trachoma Programs
BACKGROUND Defining endpoints for trachoma programs can be a challenge as clinical signs of infection may persist in the absence of detectable bacteria. Antibody-based tests may provide an alternative testing strategy for surveillance during terminal phases of the program. Antibody-based assays, in particular ELISAs, have been shown to be useful to document C. trachomatis genital infections, bu...
متن کاملControl of Trachoma from Achham District, Nepal: A Cross-Sectional Study from the Nepal National Trachoma Program
BACKGROUND The WHO seeks to control trachoma as a public health problem in endemic areas. Achham District in western Nepal was found to have TF (trachoma follicular) above 20% in a 2006 government survey, triggering 3 annual mass drug administrations finishing in 2010. Here we assess the level of control that has been achieved using surveillance for clinical disease, ocular chlamydia trachomati...
متن کاملOptimization of candidate proteins for serological screening of Chlamydia trachomatis infection.
The aim of this study was to optimize candidate antigen proteins for serological screening of Chlamydia trachomatis infection. C. trachomatis positive serum and swabs of genital secretions were collected from 50 patients in the Tianjin Medical University General Hospital, as well as from 30 patients negative for C. trachomatis. Samples were assessed by colloidal gold assay in a sexually transmi...
متن کاملSerological Measures of Trachoma Transmission Intensity
Ocular infection with Chlamydia trachomatis can lead to trachoma, a leading infectious cause of blindness. Trachoma is targeted for elimination by 2020. Clinical grading for ocular disease is currently used for evaluating trachoma elimination programs, but serological surveillance can be a sensitive measure of disease transmission and provide a more objective testing strategy than clinical grad...
متن کاملSerology for Trachoma Surveillance after Cessation of Mass Drug Administration
BACKGROUND Trachoma, caused by Chlamydia trachomatis (Ct), is the leading infectious cause of blindness worldwide. Yearly azithromycin mass drug administration (MDA) plays a central role in efforts to eliminate blinding trachoma as a public health problem. Programmatic decision-making is currently based on the prevalence of the clinical sign "trachomatous inflammation-follicular" (TF) in childr...
