Francisella tularensis Infection of Mice as a Model of Sepsis.

Abstract

Sepsis results from the dysregulated immune response to infection. While the stimulator and progression of the septic response is poorly understood, the systemic production of a storm of cytokines is common in all etiologies of sepsis. While the complexity of this uncontrolled cascade is difficult to replicate using single molecule agonist, for example, lipopolysaccharide (LPS), several whole organism models can stimulate this cytokine storm. Herein, we detail protocols developed to trigger and analyze the systemic septic response in mouse models using the bacterium Francisella tularensis.
