RESUMO.Vários fatores como desmatamento e expansão da agricultura e pecuária tem promovido o contato próximo entre animais selvagens e domésticos, levando ao compartilhamento de patógenos, dentre eles o Cytauxzoon felis. O objetivo com este trabalho é relatar um caso de cytauxzoonose em Puma concolor de vida livre proveniente da região sudoeste de Mato Grosso do Sul, Brasil. O diagnóstico foi obtido por meio de microscopia de sangue periférico e reação em cadeia da polimerase, que neste relato, caracterizou-se como achado acidental, uma vez que manifestações clínicas associadas à doença não foram observadas. A detecção de Cytauxzoon felis alerta para a necessidade de estabelecer a importância epidemiológica dos animais selvagens e o risco que representam para as populações domésticas e selvagens de cativeiro em relação aos patógenos transmitidos por carrapatos.

Several factors such as deforestation and expansion of agriculture and livestock has promoted the close contact between wild and domestic animals, leading to the sharing of pathogens, including the Cytauxzoon felis. The aim of this study is to report a case of cytauxzoonose in a free-living Puma concolor from the southwest region of Mato Grosso do Sul, Brazil. The diagnosis was obtained through microscopy of peripheral blood smear and polymerase chain reaction, that in this report, was characterized as accidental finding, since clinical manifestations associated to disease were not observed. The
The occurrence of gallstones in dogs is rare, consisting, usually, in accidental findings. The animals affected present nonspecific clinical signs or even may be asymptomatic. However, depending on the localition of the stone, can occur total obstruction of bile flow and cause rupture of gallbladder or bile ducts. The imaging exams, such as radiography and/or abdominal ultrasonography, and their correct interpretation are fundamental for evaluation of biliary system. The objective of the present review is a description of the radiographic images and ultrasonographic characteristics of cholelithiasis and choledocolithiasis in dogs.
