Human ehrlichiosis is a tick-borne zoonotic infection caused by rickettsial-like agents. Two forms, human monocytic ehrlichiosis (HME) and human granulocytic ehrlichiosis (HGE) have been described. HME is often referred to as “spotless” or rashless Rocky Mountain spotted fever. The causative agent of HME has been identified as Ehrlichia chaffeensis. The two infections are clinically indistinguishable.
