Mutations in several components of a bacterial ribosome are shown to broadly decrease antibiotic and stress sensitivity, and readily accessible reversion mutations allow these ribosomal mutations to serve as stepping stones to high level antibiotic resistance.
Killing their neighbors allows bacteria to steal genes, including antibiotic resistance genes, which we observed under a microscope, quantified, modeled, and predicted potentially guiding strategies to combat it.
Antibiotic stewardship in the outpatient setting can substantially reduce exposures of potential pathogens to common antibiotics, and complementary efforts are needed to reduce remaining exposures that occur in 'necessary' contexts.
Population-level antibiotic resistance correlates with the breadth of antibiotic use, that is, the proportion of people taking an antibiotic, better than with intensity of use the amount of use among users.
Shifts in pH that result from metabolic interactions between members of the Drosophila gut microbiota were sufficient to modulate Lactobacillus plantarum tolerance to the antibiotics rifampin and erythromycin.
