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 disease is caused by Trichuris trichiura?
Parasites – Trichuriasis (also known as Whipworm Infection) An estimated 604-795 million people in the world are infected with whipworm. Whipworm, hookworm, and Ascaris are known as soil-transmitted helminths (parasitic worms). Together, they account for a major burden of disease worldwide.
What are the signs and symptoms of Trichuris trichiura?
Trichuriasis is infection with Trichuris trichiura. Symptoms may include abdominal pain, diarrhea, and, in heavy infections, anemia and undernutrition. Diagnosis is by finding eggs in stool. Treatment is with mebendazole, albendazole, or ivermectin.
What is another name for Trichuris trichiura?
The nematode (roundworm) Trichuris trichiura, also called the human whipworm.
What is the host of Trichuris trichiura?
Humans are the only known hosts of T. trichiura. Following excretion, fertilised Trichuris eggs will mature into an embryonated infective stage, which, if consumed by a susceptible person will establish a new cycle of infection. Worldwide it has been estimated that 600–800 million persons are infected by this nematode.
What is the family of Trichuris trichiura?

How is trichuriasis treated?
Anthelminthic medications (drugs that rid the body of parasitic worms), such as albendazole and mebendazole, are the drugs of choice for treatment. Infections are generally treated for 3 days. The recommended medications are effective. Health care providers may decide to repeat a stool exam after treatment.
How can Trichuris trichiura be diagnosed?
The standard method for diagnosing the presence of whipworm is by microscopically identifying whipworm eggs in a stool sample. Because eggs may be difficult to find in light infections, a concentration procedure is recommended.
Why is Trichuris called whipworm?
Whipworm (Trichuris trichiura) is an intestinal parasite of humans. The larvae and adult worms live in the intestine of humans and can cause intestinal disease. The name comes from the worm’s whip-like shape.
How does Trichuris trichiura enter the body?

How can trichuriasis be prevented?
Prevention & Control
- Avoid ingesting soil that may be contaminated with human feces, including where human fecal matter (“night soil”) or wastewater is used to fertilize crops.
- Wash your hands with soap and warm water before handling food.
- Teach children the importance of washing hands to prevent infection.
