Hemotrophic mycoplasmas (hemoplasmas), Bartonella sp., Hepatozoon sp. and Cytauxzoon felis are prominent pathogens that circulate between cats and invertebrate hosts. The present study aimed to detect the presence of DNA from hemoplasmas, Bartonella sp., Hepatozoon sp. and Cytauxzoon felis, and then confirm it by means of sequencing, in blood samples from cats in Cuiabá, MT, Brazil. From February 2009 to February 2011, blood samples with added EDTA were collected from 163 cats that were being housed in four different animal shelters in the city of Cuiabá, state of Mato Grosso, Brazil and from 15 cats that were admitted to the veterinary hospital of the Federal University of Mato Grosso (UFMT). Out of the 178 cats sampled, 15 (8.4%) were positive for hemoplasmas: four (2.2%) for Mycoplasma haemofelis, 12 (6.7%) for 'Candidatus M. haemominutum' and one (0.5%) for 'Candidatus M. turicensis'. One cat (0.5%), a patient that was attended at the veterinary hospital, was coinfected with M. haemofelis, 'Candidatus M. haemominutum' and 'Candidatus M. turicensis', based on sequencing confirmation. Four cats were positive for Bartonella spp.: three (1.7%) for B. henselae and one (0.5%) for B. clarridgeiae. None of the animals showed Cytauxzoon sp. or Hepatozoon sp. DNA in their blood samples. This study showed that cats housed in animal shelters in the city of Cuiabá, state of Mato Grosso, are exposed to hemoplasmas and Bartonella species.

“…Although piroplasms similar to Cytauxzoon sp. have been found in cat blood smears in the state of Rio de Janeiro (MENDES-DE-ALMEIDA et al, 2007), molecular confirmation of occurrences of this parasite in Brazil has only been done in wild felids ( ANDRÉ et al, 2009;FILONI et al, 2012). On the other hand, Hepatozoon sp.…”

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.

Genetic Variability of Archived Cytauxzoon Felis Histologic Specimens from Domestic Cats in Georgia, 1995–2007

Abstract. Cytauxzoon felis infection in domestic cats has historically been nearly 100% fatal. However, increasing reports of domestic cats that survive cytauxzoonosis and reports of asymptomatic cats with C. felis infections suggest the existence of different parasite strains that vary in pathogenicity. The objective of the current study was to obtain epidemiologic information about cytauxzoonosis through genotypic characterization of archived histologic specimens from domestic cats with C. felis infections that were diagnosed in Georgia between 1995 and 2007. Such retrospective data on genetic variability will provide an historic context for current studies of C. felis genotype frequencies. Cytauxzoon felis DNA was obtained from formalin-fixed, paraffin-embedded tissues from infected cats diagnosed with cytauxzoonosis at necropsy. Genetic characterization of C. felis was performed using sequence analysis of the polymerase chain reactionamplified ribosomal internal transcribed spacer regions 1 and 2 (ITS1, ITS2). Eleven different combined ITS1 and ITS2 sequences were identified, the majority of which were identical to those previously reported in fatally infected cats from Georgia. The findings of the current study document the existence of genetically distinct C. felis populations in historical samples and, together with data from contemporary samples, demonstrate a diverse population structure for C. felis.
