However, in some states of Brazil, little information is available about the occurrence of these parasites. Blood samples were collected from 250 cats treated at a private clinic in the mountainous region of Rio de Janeiro. The samples were each subjected to a blood count, microscopic examination, and molecular research on piroplasms. The animals\u2019 clinical histories and epidemiological information were analyzed to identify the risk factors associated with infection. Ticks were recovered during the clinical care and were identified and subjected to molecular analyses to determine the presence of piroplasm DNA. Piroplasms were detected in 2.7% (7\/250) of the cats. Nucleotide sequences of Babesia vogeli were identified in six cats, while the Cytauxzoon sp. was identified in one cat. Cats displaying apathy\/weakness\/prostration and hemorrhage\/bleeding were more likely to be infected. In addition, Amblyomma aureolatum was recovered from a cat PCR-negative for piroplasms. This is the first study in Rio de Janeiro that has detected Babesia vogeli in cats. The results obtained here underscore the need for further studies in Rio de Janeiro to investigate the dynamics of such infections and the vectors involved.<\/jats:p>","DOI":"10.3390\/pathogens11080900","type":"journal-article","created":{"date-parts":[[2022,8,11]],"date-time":"2022-08-11T05:43:57Z","timestamp":1660196637000},"page":"900","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":7,"title":["Piroplasm Infection in Domestic Cats in the Mountainous Region of Rio de Janeiro, Brazil"],"prefix":"10.3390","volume":"11","author":[{"given":"Jo\u00e3o Pedro","family":"Palmer","sequence":"first","affiliation":[{"name":"Department of Microbiology and Parasitology, Biomedical Institute, Fluminense Federal University, Niter\u00f3i, Rio de Janeiro 24210-130, Brazil"},{"name":"National Reference Laboratory for Rickettsiae Vectors, Oswaldo Cruz Institute, Oswaldo Cruz Foudation, Rio de Janeiro 21040-360, Brazil"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Gilberto","family":"Gaz\u00eata","sequence":"additional","affiliation":[{"name":"National Reference Laboratory for Rickettsiae Vectors, Oswaldo Cruz Institute, Oswaldo Cruz Foudation, Rio de Janeiro 21040-360, Brazil"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-1713-5222","authenticated-orcid":false,"given":"Marcos","family":"Andr\u00e9","sequence":"additional","affiliation":[{"name":"Department of Pathology, Reproduction and Single Health, J\u00falio de Mesquita Filho College of Agrarian and Veterinary Sciences, Paulista State University, Jaboticabal 14884-900, Brazil"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Aline","family":"Coelho","sequence":"additional","affiliation":[{"name":"Department of Microbiology and Parasitology, Biomedical Institute, Fluminense Federal University, Niter\u00f3i, Rio de Janeiro 24210-130, Brazil"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"La\u00eds","family":"Corr\u00eaa","sequence":"additional","affiliation":[{"name":"Department of Microbiology and Parasitology, Biomedical Institute, Fluminense Federal University, Niter\u00f3i, Rio de Janeiro 24210-130, Brazil"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jos\u00e9","family":"Damasceno","sequence":"additional","affiliation":[{"name":"Veterinary Diagnostic Center, Niter\u00f3i, Rio de Janeiro 24230-253, Brazil"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Carolina","family":"Israel","sequence":"additional","affiliation":[{"name":"Clinic School of Veterinary Medicine Luiz Cataldi de Souza, Serra dos \u00d3rg\u00e3os University Center, Teres\u00f3polis, Rio de Janeiro 25976-345, Brazil"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Rafael","family":"Pereira","sequence":"additional","affiliation":[{"name":"Clinic School of Veterinary Medicine Luiz Cataldi de Souza, Serra dos \u00d3rg\u00e3os University Center, Teres\u00f3polis, Rio de Janeiro 25976-345, Brazil"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Alynne","family":"Barbosa","sequence":"additional","affiliation":[{"name":"Department of Microbiology and Parasitology, Biomedical Institute, Fluminense Federal University, Niter\u00f3i, Rio de Janeiro 24210-130, Brazil"},{"name":"Laboratory of Toxoplasmosis and Other Protozooses, Instituto Oswaldo Cruz, Funda\u00e7\u00e3o Oswaldo Cruz, Rio de Janeiro 21040-900, Brazil"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2022,8,11]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"99","DOI":"10.1186\/1756-3305-6-99","article-title":"Feline vector-borne pathogens in the north and centre of Portugal","volume":"6","author":"Vilhena","year":"2013","journal-title":"Parasites Vectors"},{"key":"ref_2","doi-asserted-by":"crossref","first-page":"197","DOI":"10.1016\/j.vetpar.2006.07.030","article-title":"Canine babesiosis: A Brazilian perspective","volume":"141","author":"Figueredo","year":"2006","journal-title":"Vet.
