Figure 2

A typical area where infection with the Rickettsia rickettsii bacterium occurs, manifested as Rocky Mountain spotted fever, in the metropolitan area of São Paulo, Brazil. Humans have constructed their homes in the Atlantic rainforest fragment (habitat of the Amblyomma aureolatum tick, a vector of R. rickettsii), where many dogs are unrestrained. Dogs frequently enter the forest, become infested by adult A.aureolatum ticks, and bring them into homes, allowing the direct transfer of feeding ticks
