As with all infections, Rocky Mountain Spotted Fever can trigger sepsis. Sometimes incorrectly called blood poisoning, sepsis is the body's often deadly response to infection
  6. Amblyoma americanum is a common human-biting tick. The high prevalence of R. amblyommatis in this tick may complicate the diagnosis and surveillance of other spotted fever type rickettisial infections in humans. Most cases of RMSF are diagnosed using serological assays, and it has been suggested that the cross-reactivity of antibodies to strains like WB-8-2T against R. rickettsia antigen may help explain the large number of mild RMSF cases in areas where A. americanum is prevalent (7-11)
