摘要
β-lactamases continue to be the leading cause of resistance to β-lactam antibiotics, among gram-negative bacteria. In recent years, both the incidence and the prevalence of extended-spectrum β-lactamases, inhibitor-resistant β-lactamases, AmpC-type enzymes, and both metallo-carbapenemases and nonmetallo-carbapenemases have increased. These β-lactamases provide resistance to oximino-cephalosporins, β-lactam/β-lactamase inhibitor combinations, cephamycins, and carbapenems, respectively. Strains expressing these β-lactamases will generate a host of therapeutic challenges as we begin the 21st century.
