Question

Which one or more of the following parasites is/are typically transmitted by mosquitoes as vector?

• A. ( {Leishmania donovani} )
• B. ( {Plasmodium vivax} )
• C. ( {Wuchereria bancrofti} )
• D. ( {Trichuris trichiura} )

Hint:

Understanding vector biology and control is essential in preventing diseases caused by these parasites.

Answer 1

The Correct Option is B

Mosquitoes serve as vectors for several parasitic diseases. The specific parasites that are transmitted by mosquitoes include those causing malaria and lymphatic filariasis.
Analysis of Each Option: (A) Incorrect: {Leishmania donovani}, the causative agent of visceral leishmaniasis (Kala-azar), is transmitted by the sandfly, not mosquitoes. 
(B) Correct: {Plasmodium vivax} is a well-known malaria parasite transmitted by Anopheles mosquitoes. 
(C) Correct: {Wuchereria bancrofti} causes lymphatic filariasis and is transmitted by several species of mosquitoes, including Culex, Anopheles, and Aedes. 
(D) Incorrect: {Trichuris trichiura}, a parasitic worm causing trichuriasis, is transmitted through soil-contaminated with human feces, not by mosquitoes. Conclusion:
Explanation: Mosquito vectors are critical in the life cycle and transmission of both {Plasmodium vivax} and {Wuchereria bancrofti}. Mosquito-borne transmission is key to the spread of these diseases, affecting millions of people worldwide.
