Animal EpidemiologyAbstract
This study aimed to evaluate the suspition of spotted fever (SF) occurrence in Quirinopolis city (Goias State) through serological survey in human, dogs and horses samples, and identification of tick vectors. In 2007, indirect immunofluorescence antibody test (IFAT) was carried out for Rickettsia spp. in blood samples taken from 28 persons, related to the suspected case (a 3-year-old child who showed signs of rickettsial disease after exposure to ticks). Also, blood samples were collected from five dogs and 42 horses, from which only there horses (28.6%) were seropositive. The tick Amblyomma cajennense was not found. Seven humans were reactive to Rickettsia spp., most of them were paternal relatives of the suspected case. In 2008, in the same region, IFAT was performed on 30 human samples without clinical signs of SF and 50% of them were seropositive for Rickettsia spp. Additionally, blood samples were collected from 24 stray dogs, and one of the animals showed seropositivity. Serologic evidence of the contact between the bacteria of the genus Rickettsia with human and animal inhabitants from Quirinopolis city indicates that the SF or another rickettsial disease may be occurring in Goias State, Brazil.Keywords: A. cajennense; antibodies; dogs; horses; human; Rickettsia.
