Redefining extended-spectrum beta-lactamases: balancing science and clinical need Export

@article{citeulike:3808791, abstract = {The current {beta}-lactamase classifications have reached a high level of complexity, making them less accessible to clinicians, infection control professionals, hospital management and politicians.
