The National Preclinical Sepsis Platform (NPSP) is a consortium of basic science researchers, veterinarians, and stakeholders in Canada undertaking standardized multi-laboratory sepsis research to increase the efficacy and efficiency of bench-to-bedside translation. In this study, we aimed to develop and characterize a 72-h fecal-induced peritonitis (FIP) model of murine sepsis conducted in two independent laboratories. The experimental protocol was optimized by sequentially modifying dose of fecal slurry and timing of antibiotics in an iterative fashion, and then repeating the experiIntensive care medicine experimental45https://www.ebi.ac.uk/biostudies/studies/S-EPMC10352196biostudies-literatureDevelopment and characterization of a fecal-induced peritonitis model of murine sepsis: results from a multi-laboratory study and iterative modification of experimental conditions.PMC10352196Macala KFCani EChwastek DEngelberts DDwivedi DJFergusson DAEng MSontag DCepinskas GArora JGill SEYu ILMcDonald BBourque SLSharma NLalu MMPape CNational Preclinical Sepsis Platform, Sepsis CanadaMedeiros SKPanahi SLiaw PCKuhar EMendelson AAJahandideh FSchlechte JSunohara-Neilson JFox-Robichaud AEfalseDevelopment and characterization of a fecal-induced peritonitis model of murine sepsis: results from a multi-laboratory study and iterative modification of experimental conditions.<h4>Background</h4>Preclinical sepsis models have been criticized for their inability to recapitulate human sepsis and suffer from methodological shortcomings that limit external validity and reproducibility.
