Abstract | Spotted fever (SF) is a tick-borne zoonosis caused by bacteria of the genus Rickettsia.
The disease varies in severity from mild clinical forms to severe cases. In Brazil, Rickettsia
rickettsii SF is the most serious rickettsiosis and can result in death if not diagnosed and
treated at the onset of symptoms. The SF mild form is caused by Rickettsia parkeri strain
Atlantic Rainforest, and this etiological agent has been reported in the South, Southeast
and Northeast regions of the country, in areas of preserved or little antropized Atlantic
Rainforest. Amblyomma ovale is the proven vector and dogs are the hosts associated with the
bioagent cycle. During a SF case investigation in Paraty municipality, Rio de Janeiro State,
an Atlantic Rainforest biome area in Southeastern Brazil, the human pathogen R. parkeri
strain Atlantic Rainforest was detected by PCR in a sample of human skin inoculation eschar
and in a female A. ovale tick collected from a dog. These results expand the known area of
occurrence of this mild form rickettsiosis in Brazil. In addition, the results of the present
study indicate the importance of implementing programs to control canine ectoparasites and
to raise awareness of the risks of infection, signs and symptoms of SF caused by R. parkeri
strain Atlantic Rainforest. | pt_BR |
