Related to microfilaria: Wuchereria bancrofti
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.
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.
microfilaria/mi·cro·fi·la·ria/ (-fĭ-lar´e-ah) [L.] the prelarval stage of Filarioidea in the blood of humans and in the tissues of the vector; sometimes incorrectly used as a genus name.
n. pl. microfilar·iae (-ē-ē′)
The minute larval form of a filarial worm.
[mī′krōfiler′ē·ə] pl. microfilariae
Etymology: Gk, mikros + L, filum, thread
microfilariaThe 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.
Microfilaria are distinguished by the pattern of nematode sheath and arrangement of nuclei.
• Brugia malayi—Mosquito.
• Dracunculiasis medinensis—Copepod (nematode).
• Loa loa—Tabanid fly.
• Mansonella perstans—Midges.
• Onchocerca volvulus—Black fly.
• Wuchereria bancrofti—Mosquito.
mi·cro·fi·lar·i·a, pl. microfilariae (mī'krō-fi-lar'ē-ă, -ē)
Term for embryos of filarial nematodes in the family Onchocercidae.
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.
the larva of worms in the superfamily Filarioidea. They are produced by adult worms residing in the bloodstream, tissues or body cavities, from where they can be ingested by biting insects. There they pass through a developmental stage and are transmitted to another permanent host when it is bitten by the insect. The microfilariae of some species are nocturnal and are therefore available for transmission only at night.
