Trichuris trichiura
Trichuris trichiura
Trichuris trichiura, also known as the whipworm, is a type of parasite that lives in the human intestine. It is one of the most common helminths (parasitic worms) to infect humans.
Pronunciation
Trichuris trichiura: /triˈkjʊrɪs triˈkjʊrə/
Etymology
The name Trichuris trichiura is derived from the Greek words "tricho" meaning hair and "oura" meaning tail, referring to the whip-like shape of the worm.
Description
Trichuris trichiura is a nematode worm, part of the larger group of organisms known as helminths. It is characterized by its long, thin, whip-like shape, which gives it its common name, the whipworm. The worm is typically 3-5 cm in length and lives in the large intestine of its host.
Life Cycle
The life cycle of Trichuris trichiura begins when eggs are ingested from contaminated soil. These eggs hatch in the small intestine, and the larvae then migrate to the large intestine, where they mature into adult worms. The adult worms lay eggs, which are passed out of the body in the feces. These eggs can then contaminate the soil, completing the life cycle.
Symptoms and Treatment
Infection with Trichuris trichiura can cause a range of symptoms, including abdominal pain, diarrhea, and weight loss. In severe cases, it can lead to Trichuriasis, a disease characterized by anemia, fatigue, and in children, growth retardation and cognitive delays. Treatment typically involves antiparasitic medications, such as mebendazole or albendazole.
