Abstract
The article presents the results of laboratory studies of «Tektumdez» drug's bactericidal activity against Gram-negative E. coli (sh. 1257) and Gram-positive S. aureus (sh. 209-P) microorganisms as well as disinfectant activity against microorganisms of resistance groups 3–4 in laboratory experiments. According to results of tests, bactericidal dilution of «Tektumdez» against bacteria without protein at 30-minutes exposure was 1:7778,4, against bacteria with protein – 1:2024,8, at the same exposure. Protein index was 3,84, phenolic coefficient was 40,34. In laboratory experiments, test objects made of wood, concrete, iron and plastic and contaminated with E. coli, strain 1257 were disinfected with Tektumdez within 3 hours, at a consumption rate of 150 ml/m2 and drug concentration of 0,75 %; contaminated with S. aureus (strain 209-P) in 3 hours at a drug consumption rate of 150 ml/m2 with a drug concentration of 1%, and Mycobacterium B-5 at a drug consumption rate of 170 ml/m2 in 12 hours, and 200 ml/m2 in 6 hours with a drug concentration of 1 %. Inactivation of B. cereus spores, pcs. 96 on test objects is achieved by Tektumdez in 6 hours at a consumption rate of 200 ml/m2 and drug concentration not exceeding 2 %.
