Gentamicin at Sub-Inhibitory Concentrations Selects for Antibiotic Resistance in the Environment
The majority of antibiotics used in human medicine and animal production are excreted into the environment unmodified. Antibiotics discharged into the environment at low (sub-inhibitory) concentrations have the potential to select for antibiotic resistance, which might then spread to the human microbiome. Low-level anthropogenic sources of antibiotics would have a…
