Abstract
Objective: to study bactericidal properties of metal cations against Staphylococcus aureus and Pseudomonas aeruginosa . Material and methods. Minimum inhibitory and minimum bactericidal concentrations of metal salts were determined by the method of broth dilution. The kinetics of growth and dying of S.aureus and P.aeruginosa was studied in broth culture medium in the presence of metal cations in concentrations four times exceeding the minimum bactericidal concentrations. Results. The cations of silver and copper proved to possess a marked bactericidal effect. It was showed that an increase of oxidation-reduction potential leads to an increase of the antibacterial efficiency of the metal cations. Conclusion. A relation of the oxidizing activity of the metal cations and their bactericidal action was revealed.
