Question

Clinical examination of the patient's blood helps in the detection of ______ stage of Wuchereria bancrofti.

Options

• L₁ larva

• L₃ larva

• Adult worm

• Microfilariae

Answer 1

Clinical examination of the patient's blood helps in the detection of the L₃ larva stage of Wuchereria bancrofti.

Explanation:

Wuchereria bancrofti is a roundworm parasite found in humans that is the leading cause of lymphatic filariasis. Microfilaria grows into first-stage larvae and then into third-stage infective larvae in the thoracic muscle of mosquitos. Third-stage infective larvae enter human circulation and move to the nearby lymph gland, where they develop. As a result, the patient's blood assists in recognising the L₃ larva stage of Wuchereria Bancroft during the clinical examination.
