Subcutaneous filariasis is caused by Loa loa (the African Augenwurm- Loiasis), and Onchocerca volvulus ((onchocerciasis river blindness)).

Stringy adult Filarienw├╝rmer live in lymphatic or subcutaneous tissue. Gravid females give birth to live offspring (microfilaria) that circulate in the blood or migrate through tissues. When ingested by a suitable blood-sucking insects (mosquitoes or mosquitoes), to microfilariae develop into infective larvae inoculated or stored in insect bite in the skin of the next host. Life cycles of all nematodes are up on the site of infection similar. Few Filarienarten infect humans. They can be classified based on the location of adult worms: Subcutaneous filariasis is caused by Loa loa (the African Augenwurm- loiasis) and Onchocerca volvulus ((onchocerciasis river blindness)). Lymphatic filariasis is caused by Wuchereria bancrofti, Brugia malayi and B. timori (lymphatic filariasis (w. Bancrofti, B. malayi)). Rarely causes heartworm, dog heartworm infection in humans (dirofilariosis). Some specialized laboratories have a general serological screening test for filarial infections (including Wuchereria-, Brugia-, Onchocerca- and Mansonella infections). The test is very sensitive, but can not identify the specific filarial infections and can not distinguish from a remote infection is an active infection. This distinction is less important in symptomatic travelers, the usefulness of the test for people from endemic areas, however, limits.
