The campus of the University of S\u00e3o Paulo, in southeastern Brazil, is an area endemic for Brazilian spotted fever (BSF), with high density of capybaras and Amblyomma spp., along with confirmed human cases. Besides capybaras, the university has also an in-campus high population of sheltered and free-roaming cats. Accordingly, the aim of this study was to determine the prevalence and characteristics associated with Rickettsia rickettsii, Rickettsia parkeri and Rickettsia felis exposure among cats in a BSF-endemic area. Out of 51 cats sampled, 23\/35 shelter (65.7%) and 5\/16 free-roaming (31.2%) were positive (titers \u2265 64) for at least one Rickettsia species. Ticks species were present in 3\/16 free-roaming cats (18.8%), consisting of Amblyomma spp., nymphs of Amblyomma sculptum and adult Rhipicephalus sanguineus sensu lato. Despite sharing the capybaras environment, the seropositivity among the free-roaming and shelter cats was lower than owned cats in other endemic areas. Whether equally or less exposed to rickettsial infection, compared with owned cats in endemic areas, free-roaming and shelter cats may be used as environmental sentinels for human exposure to rickettsiae in such areas.<\/jats:p>","DOI":"10.1590\/s1984-29612019092","type":"journal-article","created":{"date-parts":[[2019,11,6]],"date-time":"2019-11-06T19:30:35Z","timestamp":1573068635000},"page":"713-721","source":"Crossref","is-referenced-by-count":13,"title":["Serosurvey of Rickettsia spp. in cats from a Brazilian spotted fever-endemic area"],"prefix":"10.1590","volume":"28","author":[{"given":"Juliana Cristina Rebonato","family":"Mendes","sequence":"first","affiliation":[{"name":"Universidade Federal do Paran\u00e1, Brasil"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Louise Bach","family":"Kmetiuk","sequence":"additional","affiliation":[{"name":"Universidade Federal do Paran\u00e1, Brasil"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Camila Marinelli","family":"Martins","sequence":"additional","affiliation":[{"name":"Universidade Estadual de Ponta Grossa, Brasil"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Aurea Maria Oliveira","family":"Canavessi","sequence":"additional","affiliation":[{"name":"Universidade de S\u00e3o Paulo, Brasil"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Tatiana","family":"Jimenez","sequence":"additional","affiliation":[{"name":"Universidade de S\u00e3o Paulo, Brasil"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Maysa","family":"Pellizzaro","sequence":"additional","affiliation":[{"name":"Universidade Estadual Paulita, Brasil"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Thiago Fernandes","family":"Martins","sequence":"additional","affiliation":[{"name":"Universidade Estadual Paulita, Brasil"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Vivien Midori","family":"Morikawa","sequence":"additional","affiliation":[{"name":"Universidade Federal do Paran\u00e1, Brasil"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Andrea Pires dos","family":"Santos","sequence":"additional","affiliation":[{"name":"Purdue University, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Marcelo Bahia","family":"Labruna","sequence":"additional","affiliation":[{"name":"Universidade de S\u00e3o Paulo, Brasil"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-4182-5821","authenticated-orcid":false,"given":"Alexander Welker","family":"Biondo","sequence":"additional","affiliation":[{"name":"Universidade Federal do Paran\u00e1, Brasil"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"530","published-online":{"date-parts":[[2019,12]]},"reference":[{"issue":"2","key":"ref1","doi-asserted-by":"crossref","first-page":"115","DOI":"10.1590\/S0074-02761961000200001","article-title":"Notas de ixodologia: VIII.
