Life Cycle: The unembryonated eggs are passed with the stool .In the soil, the eggs develop into a 2-cell stage , an advanced cleavage stage , and then they embryonate ; eggs become infective in 15 to 30 days.After ingestion (soil-contaminated hands or food), the eggs hatch in the small intestine, … Trichuris trichiura commonly called the whipworm because of its characteristic whip-like shape. They are barrel-shaped, thick-shelled and possess a pair of polar “plugs” at each end. Trichuris trichiura, or whipworm, occurs in most parts of the world where other soil-transmitted helminths, e.g., Ascaris and hookworm, are found. [these species cause trichuriasis in humans and animals] Parasite morphology: Whipworms form three different developmental stages; eggs, larvae and adults. Trichuris trichiura (whipworm) was thought to be benign; however, it is now recognized that intense infection is associated with colitis and dysentery, and that moderate infection can impair development in childhood . It causes trichosis in human which is an intestinal infection caused by invasion of the colon by the adult worm. It is elongated, and barrel-shaped with a polar "plug" at each end. The eggs are ellipsoidal to barrel-shaped, measuring 50-70 µ m in length by 25-35 µ … The posterior end is more blunt and contains the anus and sex organs. T. 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. Trichuris trichiura is referred to as the whipworm because it looks like a whip with wide handles at the posterior end. Causal Agent: The nematode (roundworm) Trichuris trichiura, also called the human whipworm. One in five people, 902 million, are carriers of Trichuris trichiura worldwide with a one percent infection rate in the United States. Trichuris trichiura is typically 54 mm x 22 mm long, but sizes of the whipworm range from 49-65 mm x 20-29 mm. It is elongated, and barrel-shaped with a polar "plug" at each end. Trichuris trichiura eggs are 50-55 micrometers by 20-25 micrometers. Infection occurs when ingested eggs hatch in the intestine and develop into adults when they reach the large intestine. Brian F. Jones, Michael Cappello, in Encyclopedia of Gastroenterology, 2004. Trichuris trichiura received the common name of whipworm from their distinctive body shape. Trichuris trichiura. Morphology Trichuris trichiura Morphology, Eggs and Characteristics Trichuris trichiura is named as Whipworm because of its structure the adult worms can grow to about 3 to 5cm in length (the females are slightly longer than the males) and have very thin anterior part that looks like a whiplash and a thicker posterior part that looks like the handle of a whip hence the name Whipworm. In the soil, the eggs develop into a 2-cell stage , an advanced cleavage stage , and then they embryonate ; eggs become infective in 15 to 30 days. They are about 50 to 54 µm by about 22 to 23 µm wide. They are football-shaped, thick-shelled and possess a pair of polar “plugs” at each end. Habitat: The adult worm lives in the large intestine (caecum) of human; It can also be present in the vermiform appendix and rectum. Whipworms have an elongated anterior end that contains the mouth and esophogus that stretches into a thread-like point. The common treatment for Trichuris trichiura are the drugs Albendazol and Pyrantel and both are effective and cost efficient. Trichuris trichiura adalah nematoda usus atau cacing usus yang ditularkan melalui tanah (soil transmitted helminth) yang dapat meyebabkan penyakit trichuriasis, cacing ini disebut juga Trichocephalus dispar, Whip worm, Trichocephalus hominis, dan cacing cambuk karena bentuknya yang menyerupai cambuk. Economic Importance for Humans: Negative. They are barrel-shaped, thick-shelled and possess a pair of polar “plugs” at each end. They are football-shaped, thick-shelled and possess a pair of polar “plugs” at each end. Trichuris trichiura eggs are 50-55 micrometers by 20-25 micrometers. The name whipworm derives from the morphology of the 3- to 5-cm adult. It is estimated that 800 million people are infected. Life Cycle: The unembryonated eggs are passed with the stool . CHARACTERISTICS: Trichuris trichiura is a gastrointestinal nematode in the family Trichuridae , genus Trichuris(5). Trichuris trichiura (Whipworm). Trichuris spp. Egg Morphology; Trichuris trichiura eggs are 'football' or 'barrel' shaped with clear, mucoid-appearing polar plugs at each end. The nematode (roundworm) Trichuris trichiura, also called the human whipworm. Trichuris trichiura also known as human whipworm, is an infection of the large intestine with Trichuris trichiura, a type of roundworm (nematode).
