What is the morphology of Trichuris trichiura?
Trichuris trichiura eggs are 50-55 micrometers by 20-25 micrometers. They are barrel-shaped, thick-shelled and possess a pair of polar “plugs” at each end. The eggs are unembryonated when passed in stool.
What are the distinguishing features of Trichuris ova?
trichiura adult parasites are characterized by a long thin anterior end that lies in a burrow in the host mucosa, and thicker end that extends into the intestinal lumen. The worms are white in colour and roughly 30 to 50 mm in length(3,7).
How is trichuriasis diagnosed?
Diagnosis of trichuriasis is made by microscopic examination of stool; the characteristic lemon-shaped eggs with clear opercula at both ends are readily apparent. When anoscopy, proctoscopy, or colonoscopy is done for other indications, wiggling adult worms may be seen protruding into the bowel lumen.
Why does Trichuris trichiura cause anemia?
trichiura infection may cause anemia include ingestion of blood by the parasite, blood loss from parasite-induced lesions in the intestinal mucosa, and inflammatory responses such as tumor necrosis factor α (TNFα) leading to decreased appetite; the relative contributions of these factors being unknown [9].
What disease is caused by Trichuris trichiura?
Trichuris trichiura, also known as the human whipworm, is a roundworm that causes trichuriasis in humans. Infections involving a high-worm burden typically include distal parts of the large intestine.

This can happen when hands or fingers that have contaminated dirt on them are put in the mouth or by consuming vegetables or fruits that have not been carefully cooked, washed or peeled. People infected with whipworm can suffer light or heavy infections.
