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, 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.
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.
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 adult forms are essentially parasites of humans, causing soil-transmitted helminthiasis (STH), but also infect domesticated mammals. The juveniles are the infective forms and they undergo tissue-migratory stages during which they invade vital organs such as lungs and liver. Thus the disease manifestations can be both local and systemic.
Filariasis (Wuchereria bancrofti, Brugia malayi infection); Onchocerciasis (Onchocerca volvulus infection); Soil-transmitted helminthiasis – this includes ascariasis (Ascaris lumbricoides infection), trichuriasis (Trichuris infection), and hookworm infection (includes necatoriasis and Ancylostoma duodenale infection)
