Barrett's esophagus has 0.5% to 7% risk of progression to esophageal adenocarcinoma. The method of obtaining biopsies to diagnose Barrett's is challenging.

Effects of intestinal protozoa infection on gastrointestinal transit and contractility in experimental animals.

Three groups of animals each was orally infected with Cryptosporidia parvum oocysts, Enterocytozoon bieneusi spores or Cyclospora cayetanensis oocysts. At the time peak of colonization of infected animals, each group and its corresponding control were infused orally with radioactive isotope. Gastric emptying of isotope was significantly greater in infected compared to controls in both fasted and fed states, to determine the effect of each parasite on the contractility of longitudinal and circular muscle, isometric tension of jejunal segments was recorded.
