Abstract
The effect of tolerance to methicillin on the response to treatment of hematogenous pyelonephritis due to Staphylococcus aureus was evaluated in rats. Tolerance was defined as a ratio of minimal bactericidal concentration to minimal inhibitory concentration of ≥32. Rats that were infected with tolerant or nontolerant strains of S. aureus were treated with methicillin with equal success as judged by the number of bacteria in the kidneys and the proportion of rats with infected kidneys. In this animal model, tolerance does not play a role in the outcome of treatment.
