The activities of amikacin in the presence of sub-lethal silver nitrate(15 μM) were tested for the combinational effects against multidrug resistant clinical isolates in vitro. Silver nitrate restored the susceptibility of drug-resistant Acinetobacter baumannii and methicillin-resistant Staphylococcus aureus to amikacin. It lowered the MICs of amikacin from 〉128 μg/mL to(2–16) μg/mL and 32 μg/mL, respectively, and lowered the MICs of amikacin on extended spectrum β-lactamase-producing Pseudomonas aeruginosa and Escherichia coli from(16–32) μg/mL and 16 μg/mL to(〈1–4) μg/mL and 〈1 μg/mL, respectively.展开更多
