These infections can damage or sicken the host (humans or other ...

In their larval stage, they attach to various animals, including humans, and feed on skin, often causing itching.

Gongylonema pulchrum is the only parasite of the genus Gongylonema capable of infecting humans. Gongylonema pulchrum infections are due to humans acting as accidental hosts for the parasite. There are seven genera of spirudia nematodes that infect human hosts accidentally: Gnathostoma, Thelazia, Gongylonema, Physaloptera, Spirocerca, Rictularia.
Human parasites are divided into endoparasites, which cause infection inside the body, and ectoparasites, which cause infection superficially within the skin. The cysts and eggs of endoparasites may be found in feces , which aids in the detection of the parasite in the human host while also providing the means for the parasitic species to exit ...
