Cover Story: Metallo-β-lactamase (MBL)-producing Gram-negative bacteria are a frequent cause of healthcare-associated infections globally. The major MBLs are VIM, NDM, IMP, SPM, GIM, SIM, FIM, DIM, IMI, and HMB. Several antibiotics have been used for the treatment of patients with MBL-producing Gram-negative bacterial infections to decrease the associated high mortality. Cefiderocol, a new cephalosporin antibiotic, and the combination of aztreonam with avibactam, a new non-β-lactam β-lactamase inhibitor, are the most promising currently available antibiotics for these pathogens. Among traditional antibiotics, colistin, polymyxin B, and fosfomycin, especially in combination antimicrobial therapy, may also be considered. There are also limited data on the use of tigecycline and aminoglycosides in MBL-producing infections. View this paper
