Mansonella streptocerca (formerly Diptalonema streptocerca) is a filarial (arthropod-borne) nematode (roundworm) causing the disease streptocerciasis.It is a common parasite in the skin of humans in the rain forests of Africa, where it is thought to be a parasite of non-human primates, as well.

These worms occupy the lymphatic system, including the lymph nodes; in chronic cases, these worms can lead to the syndrome of elephantiasis. Loiasis a subcutaneous filariasis is caused by Loa loa (the eye worm). Mansonella streptocerca, and Onchocerca volvulus. These worms occupy the layer just under the skin. O. volvulus causes river blindness.
In the human host, Loa loa larvae migrate to the subcutaneous tissue, where they mature into adult worms in approximately one year, but sometimes up to four years. Adult worms migrate in the subcutaneous tissues at a speed of less than 1 cm/min, mating and producing more microfilariae. The adult worms can live up to 17 years in the human host. [5]
Cestoda is a class of parasitic worms in the flatworm phylum (Platyhelminthes). Most of the species—and the best-known—are those in the subclass Eucestoda; they are ribbon-like worms as adults, commonly known as tapeworms. Their bodies consist of many similar units known as proglottids—essentially packages of eggs which are regularly shed ...
