Gongylonema pulchrum was first named and presented with its own species by Molin in 1857. The first reported case was in 1850 by Dr. Joseph Leidy, when he identified a worm "obtained from the mouth of a child" from the Philadelphia Academy (however, an earlier case may have been treated in patient Elizabeth Livingstone in the seventeenth century [2]).
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 ...

Later, in 1828, Saint-Vincent became the first to identify the parasite on the skin of an affected person. [6] Kavallari et al. highlight that since 1936, 105 cases of D. gallinae infestations in humans have been documented in the literature. [13] D. gallinae's digestion of human blood was first documented in 1958. [28]
Because of autoinfection, humans have been known to still be infected up to 65 years after they were first exposed to the parasite (e.g., World War II or Vietnam War veterans). Once a host is infected with S. stercoralis, infection is lifelong unless effective treatment eliminates all adult parasites and migrating autoinfective larvae.
The head louse (Pediculus humanus capitis) is an obligate ectoparasite of humans. [1] Head lice are wingless insects that spend their entire lives on the human scalp and feed exclusively on human blood. [1] Humans are the only known hosts of this specific parasite, while chimpanzees and bonobos host a closely related species, Pediculus schaeffi.
“In adults, the mites rarely burrow into the skin above the neck,” Dr. Friedman says. Children often have scabies worse than adults. “Scabies can affect the entire body, including the palms ...
Pinworm infection (threadworm infection in the UK), also known as enterobiasis, is a human parasitic disease caused by the pinworm, Enterobius vermicularis. [3] The most common symptom is pruritus ani, or itching in the anal area. [1]
