'''''Elaeophora''''' is a genus of [[parasitism|parasitic]] [[nematode]]s which live attached to the interior surfaces of major arteries, veins and/or heart chambers in various large mammal hosts. Infestation with ''Elaeophora'' species is referred to as '''elaeophorosis'''. The species of ''Elaeophora'' have been found in Africa, Asia, Europe, and North America. Despite the fact that they produce [[aneurysm]]s in the arteries and heart of their hosts which measure up to 2 cm in diameter, overt clinical symptoms of infestation are seldom reported, with the notable exception of ''E. schneideri'' infestation in [[sheep]], [[elk]], and [[moose]].<ref>Pence, D.B. (1991) Elaeophorosis in wild ruminants. ''Bulletin of the Society for Vector Ecology'' 16(1):149-160.</ref>

== Taxonomy ==
The [[type species]] ''Elaeophora poeli'' was first described as ''Filaria poeli'' in 1879. In 1912, the genus ''Elaeophora'' was created to distinguish this species from the other species of the genus ''[[Filaria]]''.<ref>Railliet, A. and A. Henry (1912) Nématodes vasculicoles des Bovins annamites." ''Bulletin de la Société de Pathologie Exotique'' 5(2):115-118.</ref> ''Elaeophora'' was made the senior [[synonym (taxonomy)|synonym]] of the [[genus|genera]] ''Alcefilaria'' and ''Cordophilus'' in 1976.<ref>Anderson, R.C. and O. Bain (1976) "CIH Keys to the Nematode Parasites of Vertebrates." Commonwealth Agriculture Bureaux: Farnham, England, Vol. 3, pp. 59-116.</ref>

== General life cycle ==
Detailed life cycle studies have been reported for only one species of ''Elaeophora'' so far - ''E. schneideri''. Microfilariae (not eggs) are shed by the adult female from her attachment site inside the [[Lumen (anatomy)|lumen]] of the [[carotid artery]] of the [[parasitic life cycles|definitive host]]. The microfilariae are carried through the blood stream and become lodged in the small [[capillary|capillaries]] of the skin in the head and facial areas. Blood-feeding [[horse-fly|horse flies]] ingest the microfilariae, which develop into infective larvae in the fly. The infective larvae enter a new definitive (mammal) host through the bite wound when the fly feeds again. The infective larvae migrate to secondary [[artery|arterial]] sites, where they mature before migrating to the [[carotid artery]]. In the carotid artery, they mature into adults and reproduce sexually to produce microfilariae. It is assumed that the life cycles of other species of ''Elaeophora'' follow this general pattern.
