Caption: Roundworm obstruction. Trichinella spiralis roundworms (nematode worms) in a gross specimen of the intestines. The ruler shows the mass of worms in the intestines is 11 centimetres wide. This parasite infects mammals, including humans, pigs and dogs, following the consumption of raw or undercooked meat containing the cysts of the T. spiralis larvae. These mature into the adult form in the intestine. The adults live for about 6-8 weeks, during which time the females release large numbers of larvae which penetrate the wall of the intestine. From here they migrate around the body, causing fever and pains, and forming cysts in the muscles.

Release details: Model release not required. Property release not required.
