"A reengineered human probiotic prevents pathogen colonization via signal interference and antibiotic production"

Members of host-associated microbial communities engage in antagonistic interactions that impact microbiome community composition and pathogen colonization. Significant interest exists in leveraging these microbial conflicts to develop microbiota-based therapies for treating infectious diseases; however, developing microbiota-based therapies requires an understanding of the molecular mechanisms by which infections are controlled by microbiota.
