Fig. 4: Faecal microbiota transplantation (FMT) in mice colonised by carbapenemase-producing Enterobacterales (CPE) improves P. aeruginosa lung infection outcomes.

a Clinical disease severity score and alveolar-capillary permeability index (n = 15 mice/group). b Bacterial load in P. aeruginosa in the left lung and in the spleen (n = 15 mice/group). c Number of cells in the bronchoalveolar lavage fluid (n = 15 mice/group). Data are presented as mean values ± SD of biologically independent samples from different mice. *p < 0.05; **p < 0.01 (one-way ANOVA followed by Tukey’s post-hoc tests, see the Source Data file for the exact P-values). d Log-rank (Mantel–Cox) analysis of survival curves (n = 15 mice/group).
