Correct Answer
C. Protozoan pathogen (Trypanosoma cruzi) that causes Chagas disease in South and Central America.Explanation
Assassin bugs, also known as kissing bugs, can transmit a protozoan pathogen called Trypanosoma cruzi, which causes Chagas disease in South and Central America. Chagas disease is a tropical parasitic disease that can be transmitted through the bug's bite or through contaminated food or drink. The disease can cause symptoms such as fever, fatigue, body aches, and swollen lymph nodes. If left untreated, it can lead to serious complications, including heart and digestive system damage. Therefore, the correct answer is the protozoan pathogen that causes Chagas disease.Rate this question:

Rickettsia mooseri that causes murine typhus.
- D.
Shigella dysentariae, Salmonella typhi and Vibrio spp. that cause dysentary, typhoid fever and cholera.They have also been suspected as vectors of the viral agent that causes poliomyelitis.
- E.
Malaria, a disease caused by protozoa in the genus Trypanosoma They are also the main vectors of the viruses that cause yellow fever, West Nile fever, dengue and the other encephalitis viruses.
Correct Answer
D. Shigella dysentariae, Salmonella typHi and Vibrio spp. that cause dysentary, typHoid fever and cholera.They have also been suspected as vectors of the viral agent that causes poliomyelitis.Explanation
House flies, blow flies and flesh flies can carry Shigella dysentariae, Salmonella typhi and Vibrio spp. which are responsible for causing dysentary, typhoid fever, and cholera. These flies have also been suspected as vectors for the viral agent that causes poliomyelitis. This means that they can transmit these pathogens to humans and potentially cause these diseases.Rate this question:

- E.
Malaria, a disease caused by protozoa in the genus Trypanosoma They are also the main vectors of the viruses that cause yellow fever, West Nile fever, dengue and the other encephalitis viruses.
Correct Answer
A. Protozoan pathogens that cause African sleeping sickness (Trypanosoma gambiense and T. rhodesiense).Explanation
Tsetse flies are known to transmit protozoan pathogens that cause African sleeping sickness, specifically Trypanosoma gambiense and T. rhodesiense. These pathogens are responsible for the disease and are transmitted to humans through the bite of infected tsetse flies. The other options mentioned in the question, such as Yersina pestis (bubonic plague), Rickettsia mooseri (murine typhus), Shigella dysentariae, Salmonella typhi, and Vibrio spp. (dysentary, typhoid fever, and cholera), and the viral agent that causes poliomyelitis, malaria, yellow fever, West Nile fever, dengue, and encephalitis viruses, are not specifically associated with tsetse flies as vectors.Rate this question:

- E.
Malaria, a disease caused by protozoa in the genus Trypanosoma They are also the main vectors of the viruses that cause yellow fever, West Nile fever, dengue and the other encephalitis viruses.
Correct Answer
C. Rickettsia mooseri that causes murine typHus.Explanation
Rat fleas can transmit Rickettsia mooseri, the pathogen that causes murine typhus. This is a bacterial infection that is spread through the bites of infected fleas. The fleas become infected when they feed on rats that carry the bacteria. When the fleas bite humans, they can transmit the bacteria, leading to the development of murine typhus. This disease is characterized by symptoms such as fever, headache, rash, and muscle aches. Therefore, the correct answer is Rickettsia mooseri that causes murine typhus.Rate this question:
