| Abstract (English): |
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 rodshaped 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. [ABSTRACT FROM AUTHOR] |
| Abstract (Portuguese): |
Descrevemos um caso de yersiniose septicêmica fatal em um zogue-zogue (Plecturocebus brunneus) jovem adulto que apresentava um quadro de letargia e anemia severa. Macroscopicamente, havia acentuada desidratação e as mucosas estavam pálidas. Notou-se hepatomegalia com múltiplos pontos amarelos e esplenomegalia com múltiplos nódulos amarelos pelo parênquima. Ainda, ulcerações da mucosa do intestino grosso, linfonodos mesentéricos aumentados e hemorragia pulmonar foram observados. A avaliação histológica revelou hepatite e esplenite necrossupurativas associadas a agregados bacterianos bacilares gram-negativos intralesionais, colite ulcerativa, hiperplasia linfoide reativa e pneumonia fibrino-hemorrágica. A cultura bacteriana e identificação através do método de espectrometria de massa por ionização e dessorção a laser assistida por matriz associada ao tempo de voo confirmou o diagnóstico de yersiniose por Yersinia enterocolitica. Este estudo demonstra que a yersiniose deve ser considerada como um diagnóstico diferencial de causa de morte em zogue-zogues. [ABSTRACT FROM AUTHOR] |
