Version 2000: the new beta-lactamases of Gram-negative bacteria at the dawn of the new millennium

Microbes Infect. 2000 Aug;2(10):1225-35. doi: 10.1016/s1286-4579(00)01276-4.

Abstract

beta-lactamases of Gram-negative bacteria are evolving dynamically. New developments include the production of enzymes with novel substrate profiles, reduced susceptibility to beta-lactamase inhibitors, and the simultaneous production of multiple types of beta-lactamases. The changes represent evolutionary upgrades which provide modern pathogens with a greater potential to resist beta-lactam antibiotics and cause formidable therapeutic, infection control, and diagnostic challenges. This review is a clinically oriented outline of recent developments in the beta-lactamase production of Gram-negative bacteria.
