Idiosyncratic fitness costs of ampicillin-resistant mutants derived from a long-term experiment with Escherichia coli
J. A. Jordan, R. E. Lenski, K. J. Card
The paper examines the fitness costs of ampicillin-resistant mutants derived from Escherichia coli, finding significant variation in fitness costs not linked to resistance levels or parental backgrounds.
