In healthy humans commensal microbes are able to prevent pathogen infections, a phenomenon that is termed as colonization resistance. Antibiotic intake or a change in food consumption can result in a loss of colonization resistance, increasing the susceptibility to infections with enteric pathogens, such as
S. Typhimurium. In this study diet-dependent bacterial microbiota composition was analysed as well as the impact of specific diets on the transcriptome of
S. Typhimurium. Moreover, a galactitol-specific uptake system was characterized in more detail.
