Which of the following is NOT one of the three species of Schistosomiasis or Bilharzia mentioned?

• A. Schistosoma haematobium
• B. Schistosoma mansoni
• C. Schistosoma japonicum
• D. Schistosoma mekongi

Answer: (D)

Schistosomiasis in humans is most often taught as being caused by three main Schistosoma species: haematobium, mansoni, and japonicum. These three are associated with the classic forms of disease—urinary schistosomiasis with haematobium and intestinal schistosomiasis with mansoni and japonicum. Another species, mekongi, can also infect humans but is not included among the standard three major species described in introductory material. That makes Schistosoma mekongi the correct choice for not being one of the three commonly mentioned species.
