The role of antibiotics in the environment for the emergence, selection and transfer of antibiotic resistance
By defining concentrations that select for resistance and drive gene transfer in complex microbial communities, we will investigate if resistance promotion primarily, or even only, takes place at higher environmental antibiotic concentrations reached through other routes than via human excretions, such as pollutionfrom antibiotic manufacturing. We will also investigate if industrial pollution with antibiotics promotes the emergence of previously unknown resistance factors. We expect the results to significantly improve our scientific understanding of the role of antibiotics in the environment in the emergence, selection and transfer of antibiotic resistance. Importantly, the research will aid in scaling and directing countermeasures to where they are likely to have an impact, and thereby benefit public health in the long term.
