Circulation of spotted fever group rickettsiae among dogs seropositive for Leishmania spp. in an urban area of Brazil

Abstract INTRODUCTION: Dogs play an epidemiological role in several vector-borne diseases that affect human and animal health worldwide. We aimed to identify rickettsial circulation among dogs with canine visceral leishmaniasis (CVL) from a region endemic for both diseases. METHODS: CVL-seropositive...

Description
Summary:Abstract INTRODUCTION: Dogs play an epidemiological role in several vector-borne diseases that affect human and animal health worldwide. We aimed to identify rickettsial circulation among dogs with canine visceral leishmaniasis (CVL) from a region endemic for both diseases. METHODS: CVL-seropositive dogs were screened for spotted fever group rickettsiae using an indirect immunofluorescence assay. RESULTS: Among the CVL-positive dogs, anti-Rickettsia rickettsii antibodies were identified in one asymptomatic and one oligosymptomatic dog. CONCLUSIONS: This study shows low circulation of antibodies to R. rickettsii in CVL-seropositive dogs. It is recommended that surveillance studies in dogs should continue in order to monitor this scenario.
