Definition: The word "angleworm" originates from the Old English term "Angulus," which means "circle worm." It's a term for a type of parasite that infects worms, often causing inflammation in the body, including pain or itching. In context, it refers to an angle worm (Annona tennantii), a parasitic infection found commonly among rodents and other small animals. Angulewts feed on the skin of their hosts, causing inflammation and producing symptoms like soreness, redness, swelling, and warmth.
