ß-Lactamases in Gram-negative Bacteria

This Q and A-style book is intended to encourage a systematic and logical approach to understanding and identifying the rapidly evolving mechanisms of ß-lactam resistance in Gram-negative bacteria commonly isolated in diagnostic laboratories. I ask readers to reflect on each question and to write down the best answer before reading the explanatory section. I hope that this effort will help you to understand a topic that has critical importance for antimicrobial therapeutics and infection control.
