Which of the following pairs is not correctly matched?a)Dengue fever ...
Dengue fever – Arbovirus
Dengue fever is caused by the dengue virus, which belongs to the family Flaviviridae and the genus Flavivirus. Arboviruses are a group of viruses that are transmitted to humans by arthropods, such as mosquitoes. Therefore, this pair is correctly matched as dengue fever is indeed caused by an arbovirus.
Plague – Yersinia pestis
The plague is caused by the bacterium Yersinia pestis. It is a highly infectious disease that primarily affects rodents, but can also be transmitted to humans through fleas. Yersinia pestis is the correct causative agent for the plague, making this pair correctly matched.
Syphilis – Trichuris trichiura
This pair is not correctly matched. Syphilis is a sexually transmitted infection caused by the bacterium Treponema pallidum. Trichuris trichiura, on the other hand, is a parasitic worm that causes a different disease called trichuriasis or whipworm infection. These two organisms are not related, and therefore, this pair is not correctly matched.
Sleeping sickness – Trypanosoma gambiense
Sleeping sickness, also known as African trypanosomiasis, is caused by the protozoan parasite Trypanosoma brucei. There are two subspecies of Trypanosoma brucei that cause sleeping sickness, namely Trypanosoma brucei gambiense and Trypanosoma brucei rhodesiense. Therefore, Trypanosoma gambiense is the correct causative agent for sleeping sickness, making this pair correctly matched.
Conclusion
Among the given pairs, the pair that is not correctly matched is "Syphilis – Trichuris trichiura." Syphilis is caused by Treponema pallidum, whereas Trichuris trichiura causes trichuriasis or whipworm infection.
