To evaluate rickettsial seroprevalence and infection in dogs and ticks, during February\u2013April 2007, we collected whole blood, sera, and ticks from dogs living in the rural, peri-urban, and urban areas of Cochabamba, Bolivia. Dog sera were subjected to enzyme-linked immunosorbent assay test to detect IgG antibodies against\n                    <jats:italic toggle=\"yes\">Rickettsia rickettsii<\/jats:italic>\n                    and 68.2% of samples were found to be positive (\n                    <jats:italic toggle=\"yes\">n<\/jats:italic>\n                    \u2009=\u200930; 95% confidence interval [CI]: 52.4\u201381.4). Blood samples and ticks were tested using polymerase chain reaction to detect spotted fever group (SFG) rickettsiae.

The high infection prevalence of SFG rickettsiae in ticks and the even higher seroprevalence in dogs suggest an active circulation of agents of rickettsiosis in the study area, although there are no confirmed cases of infection in humans.
