Question

Quizplus · Accepted Answer

The presence of an organism in a peripheral blood smear at this magnification suggests that it may be a microfilaria. Brugia malayi and Wuchereria bancrofti are both known to cause lymphatic filariasis, while Onchocerca volvulus causes onchocerciasis. However, microfilariae of Onchocerca volvulus are not typically found in peripheral blood smears, whereas microfilariae of Brugia malayi and Wuchereria bancrofti are commonly found in the blood. Among these two, the shape of the nucleus of the microfilaria found in this smear is consistent with that of Wuchereria bancrofti. Therefore, the correct answer is C.
