Murine model of polymicrobial septic peritonitis using cecal ligation and puncture (CLP).
Although a number of animal models such as endotoxic shock and bacteremia have been used to study the pathogenesis of sepsis, cecal ligation and puncture (CLP) represents a peritonitis model with clinical features of polymicrobial infection comparable with those of peritonitis in humans. The CLP consists in the surgical perforation of the legated cecum of mice that results in immediate and constant drainage of cecal bacteria into the peritoneal cavity. The severity of the diseases depends on the diameter of the needle used for the perforation as well as on the number of cecal punctures. The CLP model of sepsis in mice is the most commonly used for studying the process of septic peritonitis and can be used as a preclinical model to test the efficacy of pharmacological agents for the treatment of sepsis.
