Due to the introduction of antimicrobial resistance, brand-new alternative therapies are needed. Silver was used to treat bacterial infections considering that antiquity due to its recognized antimicrobial residential or commercial properties. Here, we intended to assess the in vitro activity of colloidal silver (CS) against multidrug-resistant (MDR) Gram-negative and Gram-positive germs. An overall of 270 stress (Acinetobacter baumannii (n = 45), Pseudomonas aeruginosa (n = 25), Escherichia coli (n = 79), Klebsiella pneumoniae (n = 58)], Staphylococcus aureus (n = 34), Staphylococcus epidermidis (n = 14), and Enterococcus types (n = 15)) were utilized. The very little inhibitory concentration (MIC) of CS was identified for all pressures by utilizing microdilution assay, and time-- kill curve assays of representative recommendation and MDR strains of these germs were performed. Membrane permeation and bacterial reactive oxygen species (ROS) production were identified in existence of CS.
