The life cycle of T. solium is represented graphically below.It consists of six main steps: Figure courtesy of the CDC's Division of Parasitic Diseases. Man is the primary or definitive host, the secondary host for T.solium is pig. 2. Taenia saginata, the beef tapeworm, is highly endemic in Africa and South America, with a prevalence of greater than 90% in certain areas.The initial step in the life cycle is contamination of pastures or animal feed with human feces that contain Taenia eggs. Eggs are past by the host, and survive on the pasture. Infected humans (definitive host) excrete the eggs or gravid proglottids in their feces, passing the parasite from the gastrointestinal tract onto nearby vegetation. Melissa Held, Michael Cappello, in Encyclopedia of Gastroenterology, 2004. The body is elongated, dorso-ventrally flattened and […] LIFE CYCLE [].

Life Cycle: Taeniasis is the infection of humans with the adult tapeworm of Taenia saginata or Taenia solium.. Also known as: Cysticercus bovis — Beef tape worm — Beef measles. ... Life Cycle. Life Cycle Taeniasis is the infection of humans with the adult tapeworm of Taenia saginata, T. solium or T. asiatica. Cestodes are flat, parasitic, hermaphroditic tapeworms with complex life cycles that infect animals, including humans.

Taenia saginata and Taenia solium are two important members of the cestodes infecting man. Taenia saginata (beef tapeworm), Taenia solium (pork tapeworm) or Taenia asiatica (Asian tapeworm).T. Life Cycle and Biology Taenia saginata, the beef tapeworm, is highly endemic in Africa and South America, with a prevalence of greater than 90% in certain areas. The initial step in the life cycle is contamination of pastures or animal feed with human feces that contain Taenia eggs. []STEP 1. 1. Systemic Position Phylum: Platyhelminthes Class: Eucestoda ADVERTISEMENTS: Order: Taenioidea Genus: Taenia Species: solium Taenia is a digenetic parasite. Clinical Features of Taenia Saginata: Because of its large size, T. saginata is responsible for considerable disturbance in the normal function of the intestine; whereas T. solium may cause irritation and less intestine obstruction, vague abdominal discomfort, hunger pains, chronic indigestion and persistent diarrhoea alternating with constipation are the common symptoms. Taenia saginata/ Taenia solium 2. Life Cycle and Biology. Symptoms may occasionally include weight loss or abdominal pain. However, the exact life cycle of T. saginata was discovered around 1863 when the cattle was identified as the immediate host.
