摘要：

Only one species of spotted fever-group rickettsiae that is pathogenic for humans has been isolated in Brazil, where few physicians ave familiar with this disease. In order to obtain information on tick-borne rickettsiosis, a study was performed in the County of Santa Cruz do Escalvado, State of Minas Gerais, Brazil, where a fatal clinical case confirmed by specific immunofluorescence had been reported. Serum samples obtained from 679 humans and 96 dogs were tested by indirect immunofluorescence for detectable antibodies to spotted fever-group rickettsiae, the criterion for a positive result being a titer greater than or equal to 1:64. Seropositivity was detected in 7.14% of the humans sera examined and 13.68% of the dogs. We discuss the significance of these findings and formulate some questions emphasizing the need for further investigation.
