Lactobacillus johnsonii Targets Enteropathogenic E. coli and Citrobacter rodentium via Biofilm Disruption, Nutrient Competition, and Antimicrobial Metabolites

This dataset supports the manuscript "Lactobacillus johnsonii Targets Enteropathogenic E. coli and Citrobacter rodentium via Biofilm Disruption, Nutrient Competition, and Antimicrobial Metabolites" submitted to 'Gut Microbes'. The files include raw and processed data from in vitro antimicrobial assays, murine infection studies, qPCR analyses, and 16S rRNA sequencing, as well as supplementary figures and presentations used during data processing. Together, these data provide experimental evidence for the antimicrobial and gut-protective properties of L. johnsonii. Detailed protocols are available in the manuscript. These datasets may benefit researchers interested in probiotics, gut microbiota, antimicrobial resistance, and host–pathogen interactions. All experiments were conducted in compliance with institutional ethical guidelines.
