Investigators from Cayetano Heredia University and Johns Hopkins University are doing this study. They want to see how people and pigs get infected with a parasite, called cysticercus (known as "pig triquina"). Cysticercus attacks the meat of pigs and the brains of people. In the intestine, the parasite is known as "solitaria". This study is to see how treatment in both people and pigs works to control the disease.
