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.

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 ...
The soil-transmitted helminths (A. lumbricoides, T. trichiura, N. americanus, A. duodenale), schistosomes, and filarial worms collectively infect more than a quarter of the human population worldwide at any one time, far surpassing HIV and malaria together.
