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% concentration
was required at an exposure of 3 hours, and the consumption rate of the drug at the rate of 0,5 l/m2.
