A parasitic tapeworm found in humans, commonly infecting through undercooked pork.

The head of the tapeworm that has suckers for attachment to the intestine.

Segments of the tapeworm that contain eggs and are shed in feces.

A juvenile stage of T. solium found in infected tissues, especially pork.

A process where a human infected with adult T. solium consumes its own eggs.

Involves ingestion of eggs, development into larvae, and attachment in the intestine.

T. solium is transmitted through ingestion of undercooked pork or feces containing eggs.

Areas where T. solium infections are common, particularly in less developed countries.

Infection caused by larvae of Taenia solium in human tissues.

The larval form of T.solium found in eggs, with a thick protective shell.

Cysticercosis in the central nervous system causing neurological symptoms.

Presence of cysticerci in the subcutaneous tissue, forming nodules.

Detection using serologic assays for antibodies and antigens related to cysticercosis.

Cysticercosis affecting the eyes, potentially leading to vision problems.

A severe form characterized by large cysts in the brain, often with high mortality.

Diagnosis involves using CT and MRI to locate cysticerci and assess inflammation.

Individualized treatment includes analgesics, anti-epileptics, and cysticidal drugs.

Antiparasitic drug used for viable parenchymal cysticercosis at 15 mg/kg/day.

Used alongside albendazole to reduce inflammation in cysticercosis treatment.

Made by examining stool samples for Taenia eggs; visible segments may indicate infection.

Avoid raw or undercooked beef and pork; cook meat to recommended temperatures.

Provide evidence on cyst location, number, viability, and inflammation severity.

Involves shunting to manage hydrocephalus and excising giant cysts.

A species of tapeworm found in cattle that can infect humans.

A species of tapeworm that infects humans primarily through pork.

A type of larval stage found in some tapeworms, usually small and infective.

A larval form of certain tapeworms, characterized by a fluid-filled cyst.

Larvae associated with the Echinococcus tapeworms, forming large cysts in hosts.

Parasitic infection by tapeworms like Taenia saginata, solium, and asiatica.

Taenia saginata (beef), Taenia solium (pork), Taenia asiatica (Asian).

Animals, such as pigs and cattle, that carry tapeworm larvae.

Usually mild or absent; may include digestive problems and weight loss.

Primarily through raw or undercooked beef or pork consumption.

A fish tapeworm that can cause pernicious anemia in humans.

Also known as the dwarf tapeworm, it is rarely symptomatic in humans.

Larvae from this dog cyst tapeworm lead to solitary tissue cysts known as hydatid disease.

Larvae from this fox cyst tapeworm lead to multilocular cysts and alveolar disease.

Diagnosis for tapeworm infections usually involves finding eggs or proglottids in feces.

Taenia saginata is transmitted through ingestion of larval form found in undercooked beef.
