What is the larval stage of Taenia solium called?
Cysticercosis
Cysticercosis is the disease associated with the development of the larval form (cysticercus) of the pork tapeworm, Taenia solium, within an intermediate host.
What is the larval stage of Taenia Saginata?
The larval stages (metacestodes) of T. saginata and T. solium form distinctive pearly-white cysts (cysticerci) which appear as small (8-10mm in diameter) fluid-filled bladders (hence the common name of bladder-worms), each containing a single invaginated protoscolex (infective stage). Other Taenia spp.
What is the diagnostic stage of Taenia solium?
Intestinal infection with adult T. solium worms can usually be diagnosed by microscopic examination of stool samples and identification of ova and/or proglottids.
What are the characteristics of Taenia Solium?
Characteristics: Taenia solium is a tapeworm of the class cestoidea, order cyclophyllidea, and family Taeniidae 1. Adult worm: Mature worms are found only in humans. Adult worm grows to approximately 2-4 m. Scolex has 4 suckers and the rostellum has two crowns of horns.
What is life cycle of Taenia Solium?
The eggs or gravid proglottids migrate to the pig’s intestine and as oncospheres, break through the intestinal wall. Then, via the circulatory system, they embed themselves in the muscles of the pig and develop into cysticerci (the infective form of T. solium).
How many mature Proglottids are present in Taenia solium?
saginata adults usually have 1,000 to 2,000 proglottids, while T. solium adults have an average of 1,000 proglottids.
What is the morphology of Taenia saginata?
Taenia saginata has a very distinctive morphology. This flatworm can grow in length from 4 to 12 meters long and 2 milimeters in diameter consisting of a scolex, neck, and strobila. Adults possess a flat, ribbon-like body shape that is important for absorbing nutrients from its hosts’ intestine.
What is the differences between Taenia saginata and Taenia solium?
The key difference between Taenia solium and Taenia saginata is that the pigs are the intermediate hosts of Taenia solium, while the cattle are the intermediate hosts of Taenia saginata. Tapeworms are parasitic segmented flatworms which are several meters long.
