Trichuriasis is a parasitic infection primarily in the tissue of the cecum, appendix, colon and rectum that is caused by Trichuris trichiura (whipworm), an intestinal parasitic nematode (roundworm).
Agent (classification and taxonomy)
The phylum of Trichuris trichiura is Aschelminthes, while its class is Adenophorea, its order is Stichosmida, and its family is Trichocephaloidea. Its genus, Trichocephalus, was recorded as a more accurate name, however the generic name trichuris, which means “hair tail” (which implies that the posterior end of the worm is the attenuated section), remains the dominant name form used today.
Human Whipworm, Trichocephaliasis, and Tricuriasis are all synonyms for Trichuriasis, human infection of the Trichuris trichiura intestinal nematode. In Spanish, trichuriasis is called “Tricuriasis,” while in it is known as “Trichuriose” in French and “Peitschenwurmbefall” in German.
History of discovery
The first written record of Trichuris trichiura was made by Morgani, an Italian scientist, who identified the presence of the parasite in a case of worms residing in the colon in 1740. Exact Morphological description and figures were first recorded in 1761 by Roedere, a German physicist. Soon after morphology and visual representation of the worms, Trichuris trichiura was given taxonomy (during the 18th century).
Humans are the only known reservoir for Trichuris trichiura.
Non-biting cyclorrhaphan flies (Musca domestica, Chrysomya rufifacies, Musca sorbens, Lucina cuprina, Calliphora vicina, Chrysomya bezziana and Wohlfarthia magnifica) have been found to carry Trichuris trichiura. A study in two localized areas in Ethiopia found cockroaches were carriers for several human intestinal parasites, including Trichuris trichiura.
