Granulocytic Ehrlichiosis in Mice Deficient in Phagocyte Oxidase or Inducible Nitric Oxide Synthase

Abstract
Mice deficient in phox (gp91phox−/−) or NOS2 (NOS2−/−) were infected with the agent of human granulocytic ehrlichiosis (HGE) to evaluate the importance of these pathways in the eradication of HGE bacteria. NOS2−/−mice had delayed clearance of the HGE agent in comparison to control or gp91phox−/−mice, suggesting that reactive nitrogen intermediates play a role in the early control of HGE.
