In Brazil, capybaras and opossums are the most probable amplifier hosts for R. rickettsii, among A. cajennense ticks, and small rodents for A. aureolatum, which implies that R. gaelic needs amplifier vertebrate hosts for its perpetuation in nature, in order to create new lines of infected ticks (horizontal transmission).

Results do not support the role of A. cooperi in the ecology of R. rickettsii in the area studied, but they add two more species of ricksettsiae to the poorly developed list of species occurring in ticks in South America.
