Description

Filariasis is a parasitic disease caused by thread-like roundworms of the Filarioidea type and spread by blood-feeding black flies and mosquitoes. Eight filarial nematodes use humans as their hosts: Lymphatic filariasis is caused by Wuchereria bancrofti, Brugia malayi, and Brugia timori which occupy the lymphatic system; in chronic cases lead to the disease elephantiasis. Subcutaneous filariasis is caused by Loa loa (the eye worm), Mansonella streptocerca, and Onchocerca volvulus. These occupy the subcutaneous layer of the skin, in the fat layer. L. loa causes Loa loa filariasis, while O. volvulus causes river blindness. Serous cavity filariasis is caused by Mansonella perstans and Mansonella ozzardi, which occupy the serous cavity of the abdomen. Filariasis is diagnosed primarily through direct observation of microfilariae in the peripheral blood. Occult filariasis is diagnosed based on clinical observations and in some cases, by finding a circulating antigen in the blood. Another method of diagnosis is to examine a skin snip, which is particularly helpful in finding the dermis-residing M. streptocerca. Skin snips can be taken with a corneal-scleral punch or a scalpel and needle. The snips are then incubated in saline or an appropriate medium and then examined for microfilarae.
