A 22-year-old man came to the emergency department with a history of urethral pain and purulent discharge that developed after he had sexual contact with a prostitute. Gram stain of the discharge revealed abundant gram negative diplococci resembling Neisseria gonorrhoeae. The patient was treated with penicillin and sent home. Two days later, the patient returned to the emergency room with a complaint of persistent, (watery urethral) clear discharge. Abundant white blood cells but no organisms were observed on Gram stain of the discharge. Culture of the discharge was negative for N. gonorrhoeae but positive for C. trachomatis.
