Abstract

This study evaluated the infection caused by and agents among dogs in southern Brazil. A total of 389 dogs were tested by the indirect immunofluorescence assay (IFA) for and . Overall, 42.4% (165/389) of the dogs were seroreactive to at least one species, but only 11 canine sera reacted with another species without reacting with A total of 100 (25.7%) canine sera showed titers to at least 4-fold higher than those to any of the other rickettsial antigens, allowing us to consider that these dogs were infected by . Dogs that had direct contact with pasture or forest areas were > 2 times more likely to be seroreactive to than dogs with no such direct contact. Only 19 (4.8%) of the 389 dogs were seroreactive to
