Abstract

In Brazil, the spotted fever group (SFG) Rickettsia rickettsii check for this species in other resources and Rickettsia parkeri check for this species in other resources related species are the etiological agents of spotted fever rickettsiosis. However, the SFG, Rickettsia rhipicephali check for this species in other resources , that infects humans, has never been reported. The study of growth dynamics can be useful for understanding the infective and invasive capacity of these pathogens. Here, the growth rates of the Brazilian isolates R. rickettsii str. Taiaçu, R. parkeri str. At#24, and R. rhipicephali HJ#5, were evaluated in Vero cells by quantitative polymerase chain reaction. R. rhipicephali showed different kinetic growth compared to R. rickettsii and R. parkeri.
