Mice survival in a two-hit model of sepsis depends on intratracheal P. aeruginosa bacterial load

Sepsis is a systemic reaction in the presence of an infection characterized by an early systemic inflammatory response syndrome followed by a compensatory anti-inflammatory response syndrome. The first side of this typical immune response is responsible for widespread damage organ whereas the second part leads to an immunoparalysis increasing patients' susceptibility to secondary infections. The goal of this study is to finalize a murine model of sepsis to understand the physiopathology of sepsis and eventually test new therapeutic approaches.
