Fatal yersiniosis by Yersinia enterocolitica in a brown titi monkey (Plecturocebus brunneus)

ABSTRACT: We described a case of fatal septicemic yersiniosis in a young adult brown titi monkey (Plecturocebus brunneus) which presented lethargy and severe anemia. Postmortem external assessment revealed marked dehydration and pale pink mucous membranes. The main gross findings included enlarged liver with yellow pinpoints, enlarged spleen with yellow nodules, mucosal ulcerations in the large intestine, enlarged mesenteric lymph nodes, and pulmonary hemorrhage. Histology revealed necrosuppurative hepatosplenitis with intralesional colonies of rod-shaped gram-negative bacteria, ulcerative colitis, reactive lymphoid hyperplasia, and fibrinous and hemorrhagic pneumonia. Bacterial culture and identification using matrix-assisted laser desorption/ionization time-of-flight mass spectrometry confirmed the diagnosis of yersiniosis by Yersinia enterocolitica. This study indicated that yersiniosis should be considered as a differential diagnosis of death in brown titi monkeys.
