We show how interactions within gut microbiomes allow certain antibiotic-resistant E. coli strains to persist even without antibiotics, helping explain how resistance is maintained in the human gut.

Non-antibiotics disrupt colonization resistance against enteropathogens - Nature
Non-antibiotic drugs from a wide range of therapeutic classes can alter the ability of gut commensals to resist invasion by enteropathogens, a previously underappreciated side effect of such drugs.
