The innate response to bacterial infection lies in its first-response role of detection of a foreign organism.  By using the above described tools of Pattern-Recognition Receptors (PRRs), the innate response flags up problems while the [[:Category:Adaptive Immune System|adaptive]] response gets itself organized.  Once a foreign organism is detected, the innate system responds by engaging in cell warfare via [[Phagocytosis|phagocytosis]] and triggering the [[:Category:Inflammation|inflammatory]] response.  The release of inflammatory [[Cytokines|cytokines]] will cause an increase in vasodilation, vascular permeability and an influx of white blood cells.  [[Neutrophils|Neutrophils]] take on their primary role as phagocytes in this phase.  In addition, systemic effects of inflammatory cytokines will sustain a rise in core temperature (fever), the release of acute phase proteins from the [[Liver - Anatomy & Physiology|liver]], and bone marrow mobilization as the need for white blood cells production is increased.  Acute phase proteins will bind to bacterial cell walls, enhancing neutrophil, macrophage, and [[Complement|complement]]-initiated phagocytosis.
