Practice questions on Trypanosoma
Which of the following groups of Glossina species is insignificant in the transmission of Trypanosoma brucei rhodesiense?
- Morsitans group
- Fusca group
- None of the above
- All of the above
Answer: B. The Fusca group of tsetse flies is insignificant in transmission of T. b. rhodesiense. The Morsitans group is the main vector. ---
Which of the following groups of Glossina species is insignificant in the transmission of Trypanosoma brucei rhodesiense?
- G. fuscipes group
- G. pallidipes
- G. longipennis
- G. palpalis group
Answer: A. The G. fuscipes group (e.g., G. tachinoides, G. fuscipes) are primarily vectors of Trypanosoma brucei gambiense (West African sleeping sickness) and are typically found in riparian vegetation. G. pallidipes and G. longipennis are more associated with G. brucei rhodesiense transmission, found in woodland and savannah habitats. The G. palpalis group, while also associated with Gambiense, can play a role in Rhodesiense
Presence of triatomine bugs (kissing bugs) can predispose the population to Chagas disease, caused by the parasite Trypanosoma cruzi.
- A) Chagas disease
- B) Malaria
- C) Dengue fever
- D) Leishmaniasis
Answer: A. Triatomine bugs, also known as kissing bugs, are the vectors for Trypanosoma cruzi, the parasite that causes Chagas disease. They often bite sleeping humans and defecate near the bite wound; the parasite is then introduced into the body when the feces are rubbed into the bite or mucous membranes.
Which of the following is the vector of Trypanosoma cruzi? ---
- Reduviid bug
- Tse-tse fly
- Sand fly
- Mosquito
- Black fly
Answer: A.
