Question

Microfilariae are liberated by female Wuchereria inside

• A. Blood
• B. Lymph
• C. Body cavity
• D. Muscles

Answer 1

The correct option is B Lymph

The microfilariae are transferred into a vector, which is most common mosquito species of the genera Culex, Anopheles, Mansonia, and Aedes. Inside the mosquito, the microfilariae mature into motile larvae called juveniles; these migrate to the labium after a period around 10 days. When the infected mosquito has its next blood meal, W. bancrofti larvae are deposited from the mouthparts onto the skin of the prospective host and migrate through micro cuts in the dermis or the tract created by the proboscis into the bloodstream of the new human host. The larvae move through the lymphatic system to regional lymph nodes, predominantly in the legs and genital area. The larvae develop into adult worms over the course of a year and reach sexual maturity in the afferent lymphatic vessels.

So, the correct answer is 'Lymph'.
