microfilariaThe microscopic embryonic forms of various nematode worms that parasitize humans and animals. Microfilaria circulate in their millions in the blood and in the lymph vessels of people suffering from FILARIASIS. When taken up by a blood-sucking insect, microfilaria mature into the larval form of the worm within the body of the insect.
