Chlamydia trachomatis is the most common sexually transmitted bacterial pathogen in the United States.In 2010, a total of 1,307,893 cases of genital infections were reported, but many infections are undiagnosed and the Centers for Disease Control and Prevention (CDC) estimates 2 to 3 million new cases occur annually in the United States.C.trachomatis will not show up on Gram stains or grow on culture media.C.trachomatis will elicit an inflammatory response, so white blood cells will be present in the discharge, but no bacteria.
