Bacterial pathogens bearing acquired metallo-[beta]-lactamase (MBL) genes exhibit a broad-spectrum resistance to [beta]-lactams that is not reversible by serine-[beta]-lactamase inhibitors (e.g., clavulanate and penicillanic acid sulphones), sincc MBLs are capable of hydrolyzing most [beta]-lactams and are not susceptible to inhibitors.
