Trichuris trichiura, Trichocephalus trichiuris or whipworm, is a parasitic roundworm (a type of helminth) that causes trichuriasis (a type of helminthiasis which is one of the neglected tropical diseases) when it infects a human large intestine.
Trichuris (synonym Trichocephalus [1]), often referred to as whipworms or the silent serpent (which typically refers to T. trichiura only in medicine, and to any other species in veterinary medicine), is a genus of parasitic helminths from the roundworm family Trichuridae.
Trichuris trichiura egg Adult worms are usually 3–5 centimetres (1.2–2.0 in) long, with females being larger than males as is typical of nematodes. The thin, clear majority of the body (the anterior, whip-like end) is the esophagus, and it is the end that the worm threads into the mucosa of the colon.
Trichuris trichiura, Trichuris vulpis: large intestine, anus stool (eggs) common worldwide accidental ingestion of eggs in dry goods such as beans, rice, and various grains or soil contaminated with human feces Elephantiasis – Lymphatic filariasis: Wuchereria bancrofti: lymphatic system thick blood smears stained with hematoxylin.
The genus Trichuris is particularly well known for being a common parasite of domestic animals and less usually humans. Its common name "whipworm" refers to the shape of these worms; they look like whips with wider "handles" at the posterior end. The genera of Trichuridae are: [1] Capillostrongyloides Freitas & Lent, 1935; Liniscus
These three types of infection are therefore caused by the large roundworm A. lumbricoides, the hookworms Necator americanus or Ancylostoma duodenale and by the whipworm Trichuris trichiura. It has become the most common parasitic disease of humans worldwide. [1]
Nematodes that commonly parasitise humans include ascarids (Ascaris), filarias, hookworms, pinworms (Enterobius), and whipworms (Trichuris trichiura). The species Trichinella spiralis, commonly known as the trichina worm, occurs in rats, pigs, bears, and humans, and is responsible for the disease trichinosis.
