RESUMO Este estudo objetivou descrever o aspecto hematológico de seis onças-pardas (Puma concolor) infectadas pelo Cytauxzoon felis. Os seis casos de infecção foram identificados durante o manejo sanitário de 11 animais de um centro de reabilitação de animais silvestres. Estruturas compatíveis com piroplasmídeos foram observadas durante a avaliação do esfregaço sanguíneo e confirmadas como Cytauxzoon felis pela técnica de PCR. A análise estatística demonstrou diferença significativa (P

The maintenance of wild animals in captivity can be a source for transmission of infectious and zoonotic diseases. In February 2016, blue-fronted amazon parrots that were kept at the Centro de Reabilitação de Animais Silvestres (CRAS) of Campo Grande - MS died suddenly. The specimens were sent to the Universidade Federal de Mato Grosso do Sul (UFMS), Faculdade de Medicina Veterinária e Zootecnia (FAMEZ) to be necropsied. Anatomopathological exams were performed and organ fragments from all systems were collected for histopathological exams. Liver and spleen fragments were also collected for bacteriological exams. Histopathological exam revealed bacterial aggregates distributed through the organs. Bacteriological exam isolated Salmonella spp. from the fragments of liver and spleen. The confirmation of the genus was made by serum agglutination on slide and by the polymerase chain reaction (PCR). The genetic sequencing identified the sample as Salmonella Typhimurium.
