Trichomoniasis is an infection caused by which organism?

• A. Testicular torsion
• B. Trichomoniasis
• C. Urinary Tract Infection-UTI
• D. Spontaneous Abortion- SAB

Answer: (B)

Trichomoniasis is caused by Trichomonas vaginalis, a flagellated protozoan that infects the urogenital tract and is spread mainly through sexual contact. This organism is the etiologic agent of the infection, whereas the other options describe conditions or syndromes rather than the cause. Infections can present with vaginal discharge and itching in women, urethral symptoms in men, or be asymptomatic in many cases. Diagnosis is typically made with nucleic acid amplification testing or microscopic examination showing motile trichomonads. Treatment uses metronidazole or tinidazole for the patient and their sexual partners, with attention to avoiding alcohol during and shortly after therapy.
