Life cycle of Trichuris trichiura inside and outside the human body. The female T. trichiura produces 2,000–10,000 single-celled eggs per day. [3] Eggs are deposited from human feces to soil where, after two to three weeks, they become embryonated and enter the "infective" stage.
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 (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. Whipworm (Trichuris trichiura) is the third most common STH-causing nematode in humans. According to current estimates, nearly 800 million people are infected, the majority of them children.

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
Trichuris muris relies on direct contact with intestinal bacteria to promote hatching of the embryonated eggs. Using green fluorescent protein (GFP) and E. coli strains, the bacteria are seen to gather specifically around the opercula, which are located at the poles of the eggs. The bacteria contain type 1 fimbriae, which possess adhesin FimH ...
