Which Mycoplasmataceae has not been connected with human genital infections?

• A. Mycoplasma genitalium
• B. Mycoplasma hominis
• C. Mycoplasma pneumoniae
• D. Ureaplasma urealyticum

Answer: (C)

The main idea is where these bacteria tend to cause disease. Mycoplasma genitalium and Ureaplasma urealyticum are well known as causes of nongonococcal urethritis and other genitourinary infections, and Mycoplasma hominis is associated with pelvic inflammatory disease and bacterial vaginosis. In contrast, Mycoplasma pneumoniae is a classic respiratory pathogen, responsible for atypical pneumonia and related respiratory tract infections, not genital infections. Therefore, the organism not connected with human genital infections is Mycoplasma pneumoniae.
