microfilaria

 [mi″kro-fĭ-lar″e-ah]
the prelarval stage of Filarioidea in the blood of humans and in the tissues of the vector. This term is sometimes incorrectly used as a genus name, and is then spelled with a capital M.

mi·cro·fi·lar·i·ae

(mī'krō-fi-lar'ē-ă, -ē),
Term for embryos of filarial nematodes in the family Onchocercidae. In the past this term has been used as a generic designation (for example, Microfilaria bancrofti, M. malaya). See: Filaria.

n. pl. microfilar·iae (-ē-ē′)
The minute larval form of a filarial worm.

mi′cro·fi·lar′i·al adj.

microfilaria

The prelarval progeny of parasitic nematodes of the superfamily Filarioidea, family Onchocercidae, which measure 200–300 µm in length, 5–7 µm in diameter, and inhabit lymphatic channels.
 
Diagnosis
Microfilaria are distinguished by the pattern of nematode sheath and arrangement of nuclei.

Microfilaria vectors
• Brugia malayi—Mosquito.
• Dracunculiasis medinensis—Copepod (nematode).
• Loa loa—Tabanid fly.
• Mansonella perstans—Midges.
• Onchocerca volvulus—Black fly.
• Wuchereria bancrofti—Mosquito.

microfilaria

The 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.
