Clinical Significance
C. trachomatis, the number one cause of sexually transmitted disease in the United States is responsible for an estimated 3-4 million new cases annually. Infants born to women with chlamydial infection of the cervix are at risk acquiring an infection during vaginal birth. Gonococcal and Chlamydial urethritis may coexist. Demonstrating the presence of N. gonorrhoeae is important in initiating appropriate therapy to prevent the spread of infection.
