The intestinal microbiota provides colonization resistance against invading pathogens, limiting pathogen expansion, transmission into the environment, and infection of naïve hosts. Previously described mechanisms of microbiota-mediated colonization resistance have been identified by observing loss of colonization resistance after community perturbations such as antibiotic treatment or diet changes. Here, we identify a microbiota-mediated mechanism of colonization resistance against the intestinal bacterial pathogen Salmonella enterica serovar Typhimurium (S. Typhimurium) by comparing high-complexity communities with different levels of colonization resistance. Using two inbred mouse strains with significantly different infection dynamics and S. Typhimurium intestinal burdens, we demonstrate that Bacteroides species mediate colonization resistance against S. Typhimurium in vivo through the production of the short-chain fatty acid propionate. We show that propionate directly inhibits S. Typhimurium growth in vitro by disrupting intracellular pH homeostasis. This work provides the first mechanistic understanding of the role of individualized microbial communities in host-to-host variability of pathogen transmission.
