filaria

filaria
Common name for nematodes of the family Onchocercidae, which live as adults in the blood, tissue fluids, tissues, or body cavities of many vertebrates. The females lay partially embryonated eggs, the embryos uncoil and circulate in blood or tissue fluids as microfilariae; if ingested by an appropriate bloodsucking arthropod, larval stages develop; later, infective larvae may be deposited on another vertebrate host's skin when the arthropod seeks another blood meal. [L. filum, a thread]

n. (pl. filariae)
any of the long threadlike nematode worms that, as adults, are parasites of human connective and lymphatic tissues capable of causing disease. They include the genera Brugia, Loa, Onchocerca, and Wuchereria. Filariae differ from the intestinal nematodes (see hookworm) in that they undergo part of their development in the body of a blood-sucking insect, e.g. a mosquito, on which they subsequently depend for their transmission to another human host. See also microfilaria.
