Cysticerci

Definition

Cysticerci are the larval stage of the pork tapeworm, Taenia solium, which can cause serious infections in humans when ingested through undercooked pork or contaminated water. These larvae can migrate to various tissues, including the nervous system, leading to neurocysticercosis.

5 Must Know Facts For Your Next Test

1. Cysticerci can infect human brain tissue, causing neurocysticercosis, a major cause of acquired epilepsy worldwide.
2. The primary route of infection is through ingestion of T. solium eggs from contaminated food or water.
3. Neurocysticercosis symptoms may include seizures, headaches, and neurologic deficits.
4. Diagnosis typically involves imaging studies such as CT or MRI scans revealing cysts in the brain.
5. Treatment often includes antiparasitic drugs like albendazole and corticosteroids to reduce inflammation.
