The use of laboratory mice to investigate correlates of infectious disease, including infection kinetics, cellular alterations, cytokine profiles, and immune response in the context of an intact host has expanded exponentially in the last decade. A marked increase in the availability of transgenic mice and research tools developed specifically for the mouse parallels and enhances this research. Human granulocytic ehrlichiosis (HGE) is an emerging, zoonotic disease caused by tick-borne bacteria. The HGE agent (Anaplasma phagocytophila) is one of two recognized pathogens to cause human granulocytic ehrlichiosis (HGE). The mouse model of HGE complements in vitro tissue culture studies, limited in vivo large animal studies, and ex vivo studies of human and ruminant neutrophils, and promises new avenues to approach mechanisms of disease. In the overview reported here, we focus principally on current research into HGE pathogenesis using the mouse model. Included is a discussion of current changes in ehrlichial classification and nomenclature, a review of ehrlichial biology and ecology, and highlights of clinical disease in animals and people.
