Concept:Taenia solium, the pork tapeworm, completes its life cycle using the pig as its intermediate host and humans as its definitive host.
Explanation:Taenia solium is a parasitic flatworm responsible for taeniasis and cysticercosis in humans.
The adult worm lives in the human small intestine and releases eggs through human feces.
When pigs ingest contaminated vegetation or human excreta containing these eggs, they become infected.
Inside the pig's muscle tissues, the eggs develop into larvae known as cysticercus cysts.
Humans acquire the infection by consuming undercooked pork that harbors these larval cysts.
Since the larval stage develops inside the pig, the pig serves as the intermediate host of the parasite.
This relationship explains why Taenia solium is associated with pork rather than beef, mutton, or dog meat.
