Abstract

The article presents data on susceptibility to antiseptic preparations in antibiotic-resistant S. aureus and P. aeruginosa strains isolated from burn wounds, which were tested in single-species and double-species biofilms with varying degrees (24-hour and 48-hour) of maturity. The studies demonstrated susceptibility of S. aureus and P. aeruginosa in single- and double-species biofilms to “Prontosan”, “Betadine” and “Chlorophyllipt” and resistance to “Miramistin” and “Chlorhexidine”. The bactericidal effect was achieved at concentrations 1.64 times higher than bacteriostatic concentrations for all the antiseptics tested. A double increase in antiseptic resistance level was observed over biofilm maturation process.
