THE ACTION OF SILVER NANOPARTICLES ON BACTERIAL STRAINS
This study approaches an issue of great interest in bio-nanotechnology and nanomedicine, for example: the possibility of usage for various concentrations of colloidal silver to reduce or to neutralize the activity of certain bacteria inside organisms. The study takes into consideration reference str...

| description | This study approaches an issue of great interest in bio-nanotechnology and nanomedicine, for example: the possibility of usage for various concentrations of colloidal silver to reduce or to neutralize the activity of certain bacteria inside organisms. The study takes into consideration reference strains such as: Escherichia coli /ATCC 10536, Klebsiella pneumoniae/ ATCC 700603, Pseudomonas aeruginosa /ATCC 25668, Salmonella typhi/ ATCC 14028, Staphylococcus aureus/ ATCC 6538, Streptococcus pyogenes/ ATCC 19615 and nosocomial strains isolated from hospital units such as: Escherichia coli/CCM 2371, Klebsiella pneumoniae/CCM 1986, Pseudomonas aeruginosa/CCM 8912, Salmonella typhi/CCM 381, Staphylococcus aureus/CCM 2877, Streptococcus pyogenes/CCM 8112. The determinations were made by using the diffusion method (adapted after the Kirby-Bauer test) in the presence of colloidal silver. The results show that, in the presence of silver, the reference strains show an increased sensitivity than the nosocomial strains; the most relevant bactericide effects were observed by using a 20ppm colloidal solution. |
