Cardiomyopathy and nephropathy are well-described common diseases contributing to their morbidity and mortality; less is known about lesions affecting the gastrointestinal tract. Records from a 14-year period (2008-2022) at the Keeling Center for Comparative Medicine and Research were queried to identify instances of spontaneous gastrointestinal disease that directly contributed to the cause of death from the 235 adult owl monkeys submitted for necropsy. Of the 235, 10.6% (25\/235) had gastrointestinal disease listed as a significant factor that contributed to morbidity and mortality. Diagnoses included candidiasis (3\/25), gastric bloat (4\/25), and intestinal incarceration and ischemia secondary (11\/25), which included intussusception (4\/25), mesenteric rent (3\/25), strangulating lipoma (2\/25), intestinal torsion (1\/25), and an inguinal hernia (1\/25). Intestinal adenocarcinomas affecting the jejunum (4\/25) were the most common neoplasia diagnosis. Oral squamous cell carcinoma (1\/25) and intestinal lymphoma (2\/25) were also diagnosed. This report provides evidence of spontaneous lesions in the species that contribute to morbidity and mortality.<\/jats:p>","DOI":"10.1177\/03009858231204260","type":"journal-article","created":{"date-parts":[[2023,10,13]],"date-time":"2023-10-13T07:25:25Z","timestamp":1697181925000},"page":"316-323","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":4,"title":["Gastrointestinal
