The role of aerobic and anaerobic bacteria innon gonococcal urethritis (NGU) in men

Abstract

Objectives:To identify causative microorganisms of nongonococcal (NGU) urethritis in men. Methods: A descriptive comparative study included 240 male patients with urethritis and 40 agematched males free from urethritis was carried out. The urethral swabs were inoculated on different culture media and incubated both aerobically and anaerobically. Results: A 153 patients were considered as NGU cases. From them, 18 genera of aerobic and anaerobic microorganisms were isolated. Aerobic bacterial isolates were two times the anaerobic bacterial isolates. The type of growth was heavy among patients in comparison to scanty growth among controls. The most common microorganism in each group were Staph. epidermidis, Gardnerella vaginalis, and Bacteroides species. Conclusion: Aerobic and anaerobic microorganisms are associated with urethritis in men. The confluent growth and dramatic response after treatment by appropriate antibiotics confirm the roles of the isolated bacteria in development of NGU in men.
