Free-roaming dogs are key because they are reservoirs for the pathogen and the main hosts of the brown dog tick (Rhipicephalus sanguineus), which vectors RMSF in this region. Because coyotes (Canis latrans) can be infected with R. rickettsii and infested with Rh. sanguineus, we hypothesized that space sharing among dogs and coyotes could enhance disease risks. In summer 2021, we captured and sampled 11 coyotes at two sites in Baja California, Mexico, near population centers with human cases of RMSF, and fitted seven individuals with GPS logging collars. We also tested tissue samples, sera, and ectoparasites for DNA of R. rickettsii with PCR and used serology to detect antibodies to R. rickettsii. Finally, we deployed an array of cameras to document dog-coyote interactions. Mean home range size was 40.37 km2. Both GPS and camera data showed considerable home range overlap both between individual coyotes and between coyotes and dogs. Coyotes were active in areas where dogs occur including the domestic interface surrounding human settlements. Although none of our samples were positive for R. rickettsii on PCR, 72.7% (8\/11) of the samples were seropositive with titers \u226564. Our data confirm shared space use and risk of shared parasites and disease between coyotes and dogs.<\/jats:p>","DOI":"10.7589\/jwd-d-22-00179","type":"journal-article","created":{"date-parts":[[2023,10,24]],"date-time":"2023-10-24T06:53:53Z","timestamp":1698130433000},"page":"722-733","source":"Crossref","is-referenced-by-count":4,"title":["POTENTIAL SHARED DISEASE RISK AMONG DOGS AND COYOTES (CANIS LATRANS) EXEMPLIFIED BY THE ECOLOGY OF RICKETTSIOSIS IN A ROCKY MOUNTAIN SPOTTED FEVER-EPIDEMIC REGION IN NORTHERN MEXICO"],"prefix":"10.7589","volume":"59","author":[{"given":"Jacob","family":"Marcek","sequence":"first","affiliation":[{"name":"University of California\u2013Davis, School of Veterinary Medicine, Department of Medicine and Epidemiology, 1275 Med Science Dr., Davis, California 95616, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Janet","family":"Foley","sequence":"additional","affiliation":[{"name":"University of California\u2013Davis, School of Veterinary Medicine, Department of Medicine and Epidemiology, 1275 Med Science Dr., Davis, California 95616, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Laura","family":"Backus","sequence":"additional","affiliation":[{"name":"University of California\u2013Davis, School of Veterinary Medicine, Department of Medicine and Epidemiology, 1275 Med Science Dr., Davis, California 95616, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Gerardo","family":"Suzan","sequence":"additional","affiliation":[{"name":"Laboratorio de Ecolog\u00eda de Enfermedades y Una Salud, Departamento de Etolog\u00eda, Fauna Silvestre y Animales de Laboratorio, Facultad de Medicina Veterinaria y Zootecnia, Universidad Nacional Aut\u00f3noma de M\u00e9xico, Ciudad Universitaria, Av.
