Cysticercosis

Definition

Cysticercosis is a parasitic tissue infection caused by the larval stage of the pork tapeworm, Taenia solium. It occurs when eggs are ingested and develop into cysticerci in tissues such as muscles, brain, and eyes.

5 Must Know Facts For Your Next Test

1. Cysticercosis is contracted through ingestion of Taenia solium eggs found in contaminated food or water.
2. The condition can lead to neurocysticercosis when larvae invade the central nervous system, causing seizures and neurological symptoms.
3. Diagnosis often involves imaging techniques like MRI or CT scans along with serological tests to detect antibodies against T. solium.
4. Treatment may include antiparasitic drugs such as albendazole or praziquantel, often combined with anti-inflammatory medications to manage symptoms.
5. Prevention strategies include proper cooking of pork and maintaining good hygiene practices to avoid fecal-oral transmission.
