The aim of this study was to determine the exposure to SFGR among dogs and feeding ticks in central Italy. A total of 344 dogs and 607 adult ticks (395\n                    <jats:italic toggle=\"yes\">Rhipicephalus sanguineus<\/jats:italic>\n                    and 212\n                    <jats:italic toggle=\"yes\">Ixodes ricinus<\/jats:italic>\n                    specimens) collected from the coats of sampled animals were included in the study. Canine serum samples were analyzed by indirect fluorescent antibody technique (IFAT) for IgG antibodies against\n                    <jats:italic toggle=\"yes\">Rickettsia conorii<\/jats:italic>\n                    and\n                    <jats:italic toggle=\"yes\">Rickettsia rickettsii<\/jats:italic>\n                    .
