We studied antibacterial properties of organo-inorganic hybrid coatings on the AMg2 aluminum alloy including superhydrophilic and superhydrophobic nanotextured metal substrates with applied bacteriophage particles. Bactericidal activity of surfaces after artificial contamination with a bacterial suspension was evaluated. To increase bactericidal effect of the plates, bacteriophage was sorbed on their surface. In the experiments simulating possible spreading of HAI pathogens, higher bactericidal activity of superhydrophilic surfaces in comparison with superhydrophobic ones. Application of bacteriophage particles did not prevent primary colonization of textured metal surfaces by strains used in the experiment, but in some cases increases their bactericidal activity.
