Urethritis attributable to Neisseria meningitidis, group X: a case report

Abstract

Neisseria meningitidis, Group X, was recovered from the anterior urethra of a 27-year-old male patient with urethritis. This isolate represents the first reported recovery of this organism from this anatomic site in association with this disease. He was treated with probenicid by mouth, followed by 4.8 million units of aqueous procaine penicillin G injected intramuscularly and became asymptomatic in three days. His recovery strongly indicates that the meningococcus was the etiologic agent of the urethritis since the condition promptly cleared with penicillin therapy.
