title: Cholelithiasis in owl monkeys: seven cases.
abstract: Spontaneous cholelithiasis was found in seven owl monkeys (Aotus spp.) at necropsy. There were four male and three female animals. Antemortem clinicopathologic findings included weight loss, anemia, increased alanine aminotransferase and gamma glutamyl transpeptidase, and hyperbilirubinemia in several animals. Choleliths ranged in size from sand-like particles to 5 mm in diameter. Gallstones from five animals were analyzed by accepted analytical methods. Results showed the gallstones to be composed primarily of cholesterol (89%). The gallbladder was histologically normal in all cases examined. The etiopathogenesis of cholelithiasis in the owl monkey is unknown.
