“…Although Cytauxzoon sp. has been detected in neotropical wild felids and lions maintained in zoos in cities located in the states of São Paulo , Rio de Janeiro (Peixoto et al, 2007) and Distrito Federal , there is only a report of this parasite in domestic cats in Brazil, in the state of Rio de Janeiro (Maia et al, 2013). The present work aimed to detect the presence of species belonging to the Anaplasmataceae family, piroplasmas and Hepatozoon spp.…”

“…infections have been confirmed by molecular techniques in wild/exotic felids (PEIXOTO et al, 2007;ANDRÉ et al, 2009;FILONI et al, 2012), but few studies regarding natural cytauxzoonosis in domestic cats were solely based on the identification of parasites on blood smears (MENDES-DE-ALMEIDA et al, 2007).…”

Cytauxzoon felis and 'Candidatus Mycoplasma haemominutum' coinfection in a Brazilian domestic cat (Felis catus) AbstractThis article describes the first detection of Cytauxzoon felis, using molecular techniques, in a naturally infected domestic cat from Brazil, South America. Coinfection with 'Candidatus Mycoplasma haemominutum' was also found. The molecular identification of the piroplasmid species was performed by Polymerase Chain Reaction (PCR) and sequencing analysis. A 284 pb fragment of the gene encoding the 18S ribosomal RNA region was amplified and showed 99% identity with other C. felis strains from North America. In addition, PCR-RFLP (restriction fragment length polymorphism) analysis, which amplifies a 595 bp fragment of the gene encoding 16S ribosomal RNA of some bacterial species, identified the co-infecting species as 'Candidatus M. haemominutum'.

“…No presente relato, nenhuma manifestação clínica compatível com a cytauxzoonose foi observada, corroborando com os achados de Soares et al (2004) que detectaram o agente em uma onça parda, e André et al (2009) que identificaram material genético do protozoário em seis jaguatiricas (Leopardus pardalis), duas onças pardas e uma onça pintada (Panthera onca). Em contrapartida, doença fatal em leões (Panthera leo), tigre de bengala e tigre branco (Panthera tigres) foi descrita (Garner et al, 1996, Jakob & Wesemeier, 1996, Peixoto et al, 2007 A presença desse patógeno, na ausência de sinais clínicos, pode estar associada à eficácia do sistema imune, no entanto, a hipótese de uma estirpe menos patogênica envolvida na infecção ou, a possibilidade de que o Puma concolor atue, assim como o Lynx rufus, como hospedeiro reservatório natural da doença deve ser investigada (Meinkoth et al, 2000, Soares et al, 2004.…”

“…A infecção natural de felídeos ferais, de diferentes espécies, por piroplasmídeos, transmitidos por pulgas e carrapatos, tem sido relatada tanto em animais de cativeiro quanto de vida livre (Garner et al, 1996, Jakob & Wesemeier, 1996, Soares et al, 2004, Peixoto et al, 2007. Cytauxzoon felis, protozoário da família Teileriidae, é um dos agentes que tem sido descrito nesses indivíduos.…”

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. Palavras chave: cytauxzoonose, diagnóstico, piroplasmídeos, felino selvagem Natural infection by Cytauxzoon felis in brown ounce (Puma concolor) of free life from the southwest region of Mato Grosso do Sul, BrazilABSTRACT. 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.
