Fitness cost constrains the spectrum of marR mutations in ciprofloxacin-resistant Escherichia coli
OBJECTIVES: To determine whether the spectrum of mutations in marR in ciprofloxacin-resistant clinical isolates of Escherichia coli shows evidence of selection bias, either to reduce fitness costs, or to increase drug resistance. MarR is a repressor protein that regulates, via MarA, expression of th...
