During the ecological studies done in Costa Rica on Rocky Mountain spotted fever, we have been able to isolate 2 strains of rickettsiae from the rabbit tick Haemaphysalis leporispalustris, indistinguishable from R. rickettsii isolated from humans in our country. Moreover, serological evidence of this agent was demonstrated in convalescent guinea pigs and in the sera of the wild rabbit (Sylvilagus braziliensis).
