E-Mail A team of scientists from the University of Cologne (Germany) and the University of Uppsala (Sweden) has created a model that can describe and predict the evolution of antibiotic resistance in bacteria. Resistance to antibiotics evolves through a variety of mechanisms. A central and still unresolved question is how resistance evolution affects cell growth at different drug concentrations. The new model predicts growth rates and resistance levels of common resistant bacterial mutants at different drug doses. These predictions are confirmed by empirical growth inhibition curves and genomic data from Escherichia coli populations. The study has been published in the journal '
