filaria

Pronunciation: fi-la're-a, -e-e

Definition: 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]
