Question

In which disease does mosquito transmitted pathogen cause chronic inflammation of lymphatic vessels ?

• A. Amoebiasis
• B. Elephantiasis
• C. Ringworm disease
• D. Ascariasis

Answer 1

The Correct Option is B

 To answer the question, we need to identify which disease involves a mosquito-transmitted pathogen causing chronic inflammation of lymphatic vessels.

1. The disease in question is Elephantiasis, which is caused by the parasitic worms Wuchereria bancrofti, Brugia malayi, and Brugia timori. These parasites are transmitted to humans through the bites of infected mosquitoes.
2. Once inside the human body, these parasites primarily target the lymphatic system, leading to chronic obstruction and inflammation of the lymphatic vessels. This can cause severe swelling and enlargement of body parts, typically the legs, a condition commonly known as "elephantiasis."
3. Let's consider the options:
   • Amoebiasis: This disease is caused by the protozoan parasite Entamoeba histolytica, which is not transmitted by mosquitoes. It primarily affects the intestines.
   • Elephantiasis: Correctly correlated with mosquito transmission and chronic lymphatic inflammation.
   • Ringworm disease: A fungal infection affecting the skin, not related to mosquito transmission.
   • Ascariasis: Caused by the intestinal roundworm Ascaris lumbricoides and not transmitted by mosquitoes.
4. Thus, the correct answer is Elephantiasis, as it is directly linked to mosquito transmission and chronic inflammation of the lymphatic vessels.

To conclude, Elephantiasis aligns perfectly with the description in the question, where the involvement of mosquito-transmitted pathogens results in inflammation of the lymphatic vessels. This validates our choice.
