Mansonella streptocerca

Man·son·el·la strep·to·cer·'ca

a filarial species in humans that produces nonperiodic sheathless microfilariae found in the circulating blood; may cause a lichenoid condition or edema of the skin; commonly found in the corium of the skin of west African residents and transmitted by the biting midge, Culicoides grahami.

Mansonella streptocerca

A filiarial nematode that, like Loa loa and Onchocerca volvulus, causes subcutaneous filariasis.

Life cycle
M streptocerca has two hosts: (1) the midge, which inoculates the human host with larvae that develop into adults in the skin, where they reproduce and give rise to (2) microfiliaria, some of which reach the bloodstream and are ingested by midges, where they develop into larvae, repeating the cycle.
