Abstract
The disinfecting effectiveness of solutions of the new domestic drug "Vortex" was studied in laboratory conditions. During the research, reference strains of the following cultures were used: Escherichia coli (pcs. 1257), Staphylococcus aureus (pcs. ATCC 6538-P FDA 209-P), Mycobacterium (pcs. B-5), Bacillus cereus (pcs. 96) and test samples of smooth and rough (solutionabsorbing materials) surfaces of five types: stainless steel, tile and broom tile, wood, concrete. The results obtained showed that the studied sample of the drug «Vortex» showed disinfectant activity in relation to gram-positive and gram-negative microorganisms. Disinfection of smooth (stainless steel, tile) test surfaces artificially contaminated with E. coli pcs. 1257 and S. aureus pcs. ATCC 6538-P FDA 209-P, was achieved at a concentration of 1.5% at the rate of 0.25...0.3 l/m2, exposure 1 hour. For disinfection of rough test surfaces made of wood and concrete, artificially contaminated with mycobacteria, pcs. B-5, a single irrigation with a solution of 4.0% concentration was required at an exposure of 3 hours, and the consumption rate of the drug at the rate of 0.5 l/m2.
