title: Utility of Direct Fluorescent Antibody Test for detection of Chlamydia trachomatis and its detection in male patients with non gonococcal urethritis in New Delhi.
abstract: The purpose of this study was assessment of prevalence of Chlamydia trachomatis and utility of Direct Fluorescent Antibody (DFA) test for its detection in male patients with non gonococcal urethritis in New Delhi, India. Thirty male patients with symptoms of dysuria showing polymorphs in their gram stained urethral smears with no evidence of Neisseria gonorrhoeae, and negative for Trichomonas vaginalis and Candida albicans by wet mount were subjected to DFA test for detection of C. trachomatis in urethral samples. Microscopic examination of gram stained urethral smears revealed 5-7 polymorphs/HPF in 90% of the patients. Evidence of C. trachomatis with DFA (MicroTrak) was detected in 11 cases (36.67%) when a cut off of 10 elementary bodies was considered essential. It is concluded that C. trachomatis is an important cause of non gonococcal urethritis in male patients in New Delhi and DFA test is a useful diagnostic tool in its detection. Where facilities are not available for its detection antichlamydial therapy should be recommended emperically.
