Abstract

Multi-resistant bacteria, the causes of nosocomial infections, such as Acinetobacter baumannii and Klebsiella pneumoniae, represent a global problem of the 21st century. The increasing resistance of these microorganisms to commercially available disinfectants is of a particular concern. The aim of our study was to determine disinfection effectiveness of the product "Sanosil super25", in relation to hydrogen peroxide, to multiple resistant isolates of A. baumannii and K. pneumoniae. The tested parameters were: MTC values (maximum tolerated concentration); MIC (minimum inhibitory concentration) and MBC (minimum bactericidal concentration). The MTC of Sanosil (<1.25 ppm) was twice as low as that of hydrogen peroxide. Sanosil MICs (1.25 or <1.25 ppm) were 4-fold lower than hydrogen peroxide. The MBC resulting in the absence of viable bacteria for Sanosil was <1.25 ppm after only 5 minutes of contact, which is at least 8 times lower concentration than hydrogen peroxide. The results showed that Sanosil super25 was more effective in all three categories, compared to hydrogen peroxide.
