Which of the following is a parasitic disease that affects lymph nodes and lymph vessels?

Correct option is C

Ans: (c) Filariasis Sol. Filariasis is a parasitic disease caused by infection with filarial worms, which are transmitted through mosquito bites. The infection affects the lymph nodes and lymph vessels, leading to lymphatic obstruction, which can result in elephantiasis (swelling of body parts, especially limbs).
Explanation of each option:
· (a) Malaria: Malaria is caused by the Plasmodium parasite and affects red blood cells, not the lymphatic system.
· (b) Typhoid: Typhoid is a bacterial infection caused by Salmonella typhi that primarily affects the gastrointestinal system.
· (c) Filariasis: Correct answer. Filariasis is caused by filarial worms and affects the lymphatic system, causing swelling and damage to the lymph vessels.
· (d) Tuberculosis: Tuberculosis primarily affects the lungs, although it can spread to other organs, including the lymph nodes. However, it is not classified as a parasitic disease.
