Taenia solium, the pork tapeworm, belongs to the cyclophyllid cestode family Taeniidae. It is found throughout the world and is most common in countries where pork is eaten. It is a tapeworm that uses humans ( Homo sapiens ) as its definitive host and pigs (family Suidae ) as the intermediate or secondary hosts .
It is feasible because there are no animal reservoirs besides humans and pigs. The only source of Taenia solium infection for pigs is from humans, a definite host. Theoretically, breaking the life cycle seems easy by doing intervention strategies from various stages in the life cycle. [33] [34] [35]
Life cycle of Taenia solium [11] Taenia solium is a tapeworm in the Cestoda class and is a species of the genus Taenia. [25] It has two hosts, pigs and humans. Pigs and humans can act as intermediate hosts for the larval form, but humans are the only definitive hosts for the adult tapeworm.
Taenia solium adult. Infection in the intestines by the adult T. solium worms is normally asymptomatic. Heavy infection can result in anaemia and indigestion. [citation needed] A complication, known as cysticercosis, may occur if the eggs of the pork tapeworm are eaten. This typically occurs from vegetables or water contaminated by feces from ...
In the normal life cycle of Taenia, cysticerci develop in the muscles of the intermediate hosts such as pigs, cattle, and sheep. In these animals, they do not cause severe symptoms. They are transmitted to humans when their infected meats are eaten. [8] [9] However, T. solium is unusual because its

Most except caryophyllideans consist of a few to 4000 proglottids (segments) that show a characteristic body differentiation pattern into scolex (head), neck, and strobila. [ 2 ] The scolex, located at the anterior end, is a small (usually less than 1 mm) holdfast organ with specific systems for fastening itself to materials: rostrum, acetabula ...
Raw or undercooked meats are the major sources of Taenia (pork, beef and venison), Trichinella (pork and bear), Diphyllobothrium (fish), Clonorchis (fish), and Paragonimus (crustaceans). Schistosomes and nematodes such as hookworms ( Ancylostoma and Necator ) and Strongyloides can penetrate the skin directly.
