If the symptoms of an illness suggest ehrlichiosis, special blood tests . Agents of human tick-borne ehrlichioses are small (approximately 0.4-1.5 m), obligately intracellular Gram negative bacteria that replicate in membrane-bound compartments inside host granulocytes (A. phagocytophilum and E. ewingii) or mononuclear phagocytes (E. chaffeensis and E. canis) ( 17, 18) ( Figure 2 ).
