Relationship between the dominant pharmacokinetic/pharmacodynamic (PK/PD) index, efficacy, and resistance emergence in vitro (both quantified by the number of bacterial colony-forming units). The PK/PD index is related to efficacy in a sigmoid curve and the resistance emergence by an inverted U-shaped curve (21).

¹This article is based on presentations and discussions held at the Second Colloquium of the International Forum on Antibiotic Resistance (IFAR), held on September 13, 2003, in Chicago, Illinois, USA. IFAR is a multidisciplinary, international group concerned with evaluating current knowledge regarding antimicrobial drug resistance and the means for its control. This article represents the opinions of the participants at the second IFAR colloquium and not necessarily those of the institutions for whom they work.
