Which organism is most closely associated with a foul smelling discharge in females?

• A. Trichomonas vaginalis
• B. Giardia Intestinalis
• C. Plasmodium species
• D. Schistosoma mansoni

Answer: (A)

The main idea here is recognizing which microbe causes a vaginal infection that produces a foul-smelling discharge. Trichomonas vaginalis is a flagellated protozoan that infects the urogenital tract and is the classic cause of trichomoniasis in women. This infection often presents with a malodorous, sometimes frothy discharge, along with itching or irritation. Exam findings can include a “strawberry cervix” in some cases. Among the options, this organism is the one that directly colonizes the vaginal area and leads to the foul odor. The other organisms relate to different body systems: Giardia intestinalis affects the gastrointestinal tract and causes diarrhea; Plasmodium species cause malaria with fevers and systemic symptoms; Schistosoma mansoni causes intestinal schistosomiasis with abdominal pain and blood in stool.
