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]).
Nematomorpha (sometimes called Gordiacea, and commonly known as horsehair worms, hairsnakes, [1] [2] [3] or Gordian worms) are a phylum of parasitoid animals superficially similar to nematode worms in morphology, hence the name. Most species range in size from 50 to 100 millimetres (2.0 to 3.9 in), reaching 2 metres (79 in) in extreme cases ...

Pinworm infection occurs worldwide, [10] and is the most common helminth (i.e., parasitic worm) infection in the United States and Western Europe. [18] In the United States, a study by the Center of Disease Control reported an overall incidence rate of 11.4% among people of all ages. [ 18 ]
Once ingested by the insect the worm larva penetrates the gut wall and develops in a cyst in the tissue outside. [4] It emerges as an adult worm in a few months. [3] Gordius worms have been recovered from human vomit, [7] feces, [8] and urine. When worms are expelled from the gastrointestinal tract, their mode of entry was likely ingestion of ...
Elaeophora schneideri (arterial worm; carotid worm; cause of elaeophorosis, aka "filarial dermatitis" or "sorehead" in sheep; or "clear-eyed" blindness in elk) is a nematode which infests several mammalian hosts in North America. It is transmitted by horse-flies.
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]
