- n. Any of various slender, threadlike nematode worms of the superfamily Filarioidea that are parasitic in vertebrates and are often transmitted as larvae by mosquitos and other biting insects. The adult form lives in the blood and lymphatic tissues, causing inflammation and obstruction that can lead to elephantiasis.

- n. a small, slender nematode worm of the family Onchocercidae (Filariidae) of many species, parasitic when adult in various animals, including man. They may live within the blood, or in other bodily fluids, or within tissues or cavities of the body. Infection with such organisms may be transmitted by blood-sucking arthropods.
- n. a former genus comprised of certain nematodes, now classed as belonging to several genera within the family Onchocercidae. See onchocerca and guinea worm.
from The Century Dictionary and Cyclopedia
- n. The typical genus of the family Filariidæ, containing parasitic nematode worms of very slender filiform shape, some attaining a length of several feet.

D. filaria, the large lungworm of sheep and goats, may occasionally be present and be a cause of a clinical pneumonia.
Note: where Loiasis is endemic (West Africa), all treatment with diethylcarbamazine, should commence with 3 mg/kg x 2 days (protocole for Loiasis) whatever form of filaria is being treated.
For example, filaria is widespread in the project area, including both river blindness and loa-loa.
Manson was moreover guided by his experience regarding another parasite of the blood, a little worm, filaria, the transference of which from one part of its life-cycle to another he had found effected by the mosquito, and more particularly by special species of the mosquito.
These are the larval forms of the parasite and have been called by Le Dantec the micro-filaria.
_Culex microannulatus_ regarded as the carrier of the filaria.
Manson's theory in regard to the disease being caused by filaria.
Soon after this, in 1879, the first conclusive proof of the direct transmission of a disease from man-to-man was presented by the father of tropical medicine, Sir Patrick Manson, with regard to filaria, a blood infection that often causes the repulsive condition known as elephantiasis and which the mosquito takes from man and after a short time gives over to another subject.
The _S. filaria_ is thread-like and the _S. refuscens_ hair-like in appearance.
-- The two lung worms of sheep are the _Strongylus filaria_ and Strongylus_ rufescens_.
