46 out of 58
 

A 23-yrs-old male senior presents to you with symptoms of a suspected sexually transmitted disease (STD). Neisseria and chlamydia agents were ruled out. Which of the following organisms was the most likely cause of his nongonococcal urethritis (NGU)?



A Mycoplasma fermentans

B Mycoplasma hominis

C Mycoplasma mycoides

D Ureaplasma urealyticum

Ans. D Ureaplasma urealyticum

a. U. urealyticum has been associated with NGU as well as infertility. M. pneumoniae is the etiologic agent of primary atypical pneumonia.

b. M. hominis, although isolated from up to 30% of patients with NGU, has yet to be implicated as a cause of that disease. M. fermentans has on rare occasions been isolated from the oropharynx and genital tract.
