C2 - Cysticercosis Flashcards
causes cysticercosis
cyst of Taenia solium
three parts of T. solium
- scolex
- neck
- strobila
fragile outer shell that can be shed as it exits the host’s body
eggs
cyst formed by larvae of T. solium
cysticerci
when cysts are found in brain or CNS
neurocysticercosis
life cycle of T. solium
- eggs in feces
- ingested by normal intermediate host
- oncospheres hatch, penetrate intestinal wall and circulate to muscle
- oncosphere develop into cysticerci
mode of transmission of cysticercosis
- fecal-oral transmission
- autoinfection
ingesting contaminatedfood or water or when humans put contaminatedfingers in their mouth
Fecal-oral transmission
when someone with a tapeworm infects themselves with tapeworm eggs.
Autoinfection
pathogenesis of cysticercosis
- larvae embed tehmselves in tissues
- migrate to brain
- leads to inflammation as they degenerate, causing scarring or encephalitis
