An infection consisting of a few small cysticerci in the liver or muscles would likely result in no obvious disease and go unnoticed. The severity of cysticercosis depends on which organs are infected and the number of cysticerci. When the person ingests the eggs, the embryo escape from the shell and penetrates the intestinal wall, gets into the blood vessels, where they spread to muscle, or more seriously, the eyes, heart or brain. Human cysticercosis occurs either by the direct transfer of Taenia solium eggs from the feces of people harboring an adult worm to their own mouth (autoinfection) or to the mouth of another individual, or indirectly by ingestion of food or water contaminated with the eggs. Symptoms of infection, if any, are general: nausea, intestinal upset, vague abdominal symptoms such as hunger pains, diarrhea and/or constipation, or chronic indigestion. Most people are asymptomatic and only become aware of the tapeworm by noticing segments of the worm in their feces. Here the tapeworm attaches to the intestine and produces thousands of eggs.ĭoes the pork tapeworm cause disease while in the intestine?
