E. coli bacteria often carry multiple drug-resistance plasmids, and under stress, readily transfer those plasmids to other species. Indeed, E. coli is a frequent member of biofilms, where many species of bacteria exist in close proximity to each other. This mixing of species allows E. coli strains that are piliated to accept and transfer plasmids from and to other bacteria. Thus, E. coli and the other enterobacteria are important reservoirs of transferable antibiotic resistance. [46]
