Final answer:
Round helminths or roundworms in swine indicate trichinosis, caused by consuming undercooked meat with Trichinella spiralis larvae. Correct answer is c.
Step-by-step explanation:
Correct answer is c. The presence of round helminths or roundworms in swine is a symptom of the parasitic disease known as trichinosis. This condition is caused by the consumption of food, particularly pork, that contains larvae of the parasite Trichinella spiralis or other Trichinella species. These larvae are encapsulated in cysts in the meat, and upon consumption, they can mature into adults within the host's large intestine and subsequently migrate to muscle tissue where they form new cysts.
The presence of roundworms in swine is a symptom of trichinosis, which is caused by a parasite called Trichinella spiralis. This parasitic disease is commonly transmitted through the consumption of undercooked or raw pork that contains the larvae of the roundworm. Once ingested, the larvae develop into mature adults within the large intestine and can migrate to the muscles, forming cysts and causing trichinosis.
