Filariasis (B74)
Clinical Information
Elephantiasis, Filarial - Parasitic infestation of the human lymphatic system by WUCHERERIA BANCROFTI or BRUGIA MALAYI. It is also called lymphatic filariasis.
Filariasis - Infections with nematodes of the superfamily FILARIOIDEA. The presence of living worms in the body is mainly asymptomatic but the death of adult worms leads to granulomatous inflammation and permanent fibrosis. Organisms of the genus Elaeophora infect wild elk and domestic sheep causing ischemic necrosis of the brain, blindness, and dermatosis of the face.
Filarioidea - A superfamily of nematodes of the order SPIRURIDA. Members possess a filiform body and a mouth surrounded by papillae.
Loiasis - A parasitic infection caused by the nematode Loa loa. The vector in the transmission of this infection is the horsefly (Tabanus) or the deerfly or mango fly (Chrysops). The larvae may be seen just beneath the skin or passing through the conjunctiva. Eye lesions are not uncommon. The disease is generally mild and painless.
Mansonella - A genus of parasitic nematodes whose organisms are distributed in Central and South America. Characteristics include a smooth cuticle and an enlarged anterior end.
Mansonelliasis - Infection with nematodes of the genus MANSONELLA. Symptoms include pruritus, headache, and articular swelling.
