title: Eschar-associated spotted fever rickettsiosis, Bahia, Brazil.
abstract: In Brazil, Brazilian spotted fever was once considered the only tick-borne rickettsial disease. We report eschar-associated rickettsial disease that occurred after a tick bite. The etiologic agent is most related to Rickettsia parkeri, R. africae, and R. sibirica and probably widely distributed from Sao Paulo to Bahia in the Atlantic Forest.
