Abstract
Rickettsial infections in pets have not been documented in Chile. Some of those infections have relevant zoonotic potential. To report two serologically confirmed cases of canine rickettsiosis. To determine seroprevalence to Rickettsia sp in a group of dogs. IgG antibodies anti-R. conorii and anti-A. phagocitophilum by IFI in two dogs with clinical rickettsiosis. IgG antibodies anti-R. conorii in a group of 77 dogs. a dog presented with fever, myalgias and melena, another dog with bleeding and neurological involvement. Seroprevalence: 35% of the dogs had antibodies against Rickettsia. This is the first evidence of canine rickettsiosis in Chile, both clinical and serological. Co-infection with two tickborne agents: Rickettsia and Anaplasma, is documented. Molecular studies are needed to confirm the rickettsial species present in Chile. The zoonotic role of these infections must be also studied.
