Occurrences of BSF in the northeast of the state of Paran\u00e1 prompted investigation of areas at risk of this rickettsiosis in the municipalities of Japira, Jaboti, Pinhal\u00e3o and Tomazina. To determine the areas at risk, 592 serum samples from dogs and 230 from equids were analyzed by means of the indirect immunofluorescence assay (IFA) for Rickettsia rickettsii and R. parkeri . In addition, risk probability maps were drawn up using the kriging indicator technique. Among the samples tested, 5.3% (43\/822) indicated presence of antibodies reactive to at least one of the two Rickettsia species tested: 7.8% of the equids (18\/230) and 4.2% of the dogs (25\/592) were positive. Geostatistical analysis showed that the average seropositivity rate was 5 to 6%. Although the average seropositivity rates observed among these dogs and equids were lower than those reported from endemic areas of Brazil, the biotic components (etiological agent, vector and reservoirs) and environmental aspects of BSF epidemiology were present in these municipalities.<\/jats:p>","DOI":"10.1590\/s1984-29612016060","type":"journal-article","created":{"date-parts":[[2016,11,30]],"date-time":"2016-11-30T21:42:10Z","timestamp":1480542130000},"page":"394-400","source":"Crossref","is-referenced-by-count":5,"title":["Probability of occurrence of the Brazilian spotted fever in northeast of Paran\u00e1 state, Brazil"],"prefix":"10.1590","volume":"25","author":[{"given":"Fl\u00e1vio Haragushiku","family":"Otomura","sequence":"first","affiliation":[{"name":"Universidade Estadual do Norte do Paran\u00e1, Brasil;
