The Taeniidae / t ɪ ˈ n aɪ. ɪ d iː / are a family of tapeworms.It is the largest family representing the order Cyclophyllidea. [1] It includes many species of medical and veterinary importance, as Taenia solium (pork tapeworm), Taenia saginata (beef tapeworm), and Echinococcus granulosus.
Neurocysticercosis (NCC) is a parasitic infection of the nervous system caused by the larvae of the tapeworm Taenia solium, also known as the "pork tapeworm". The disease is primarily transmitted through direct contact with human feces, often through the consumption of food or water containing Taenia solium eggs.
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 ...
The Taenia saginata remains asymptomatic due to the fact the organism does not present cysticerci in humans. Therefore, there is no presence of cysticercosis in humans either. Typically, cysticercosis is a parasitical tissue infection which infect the brain and muscle tissues. However the Taenia saginata can cause taeniasis, which is an ...
Taenia solium eggs and proglottids found in feces, ELISA, or polyacrylamide gel electrophoresis diagnose only taeniasis and not cysticercosis. Radiological tests, such as X-ray, CT scans which demonstrate "ring-enhancing brain lesions", and MRIs, can also be used to detect diseases. X-rays are used to identify calcified larvae in the ...
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 became a tradition to refer to the larvae of Taenia solium as Cysticercus cellulosae, that of beef tapeworm (T. saginata) as Cysticercus bovis, that of sheep tapeworm (T. ovis) as Cysticercus ovis, that of ruminant tapeworm (T. krabbei) as Cysticercus tarandi, and that of the dog tapeworm (T. crassiceps) as Cysticercus longicollis.
Contaminated food may contain eggs of nematodes such as Ascaris, Enterobius, and Trichuris; cestodes such as Taenia, Hymenolepis, and Echinococcus; and trematodes such as Fasciola. Raw or undercooked meats are the major sources of Taenia (pork, beef and venison), Trichinella (pork and bear), Diphyllobothrium (fish), Clonorchis (fish), and ...
