The purpose of our work was to compare the effect of natural and synthetic antiseptics on clinical strains of microorganisms (S.aureus, S.pyogenes, K.pneumoniae, K.rhinoscleromatis), which caused infections of the upper respiratory tract. The antimicrobial action of the antiseptics (sanguiritrinum, chlorophyllipte, decasan, miramistin) was studied on 26 clinical strains. For comparative antimicrobial asssay, the double dilution test was used; the antiseptic activity index (AAI) was counted; a quantitative suspension test was performed in order to estimate decontaminating ability of studied antiseptics. The bactericidal action of decasan and myramistin on clinical strains of S.aureus and S.pyogenes did not exceed 8 μg / ml, the same activity of sanguviritrin was observed at 16–26 μg / ml, and chlorophyllitine at 55–94 μg / ml, respectively. Klebsiella had high sensitivity to decasan, sanguiritrinum, myramistin (MCC from 2.5 to 20 μg / ml). High AAIs of all antiseptics was revealed for S.aureus (from 8.5 for chlorophyllipte and 78.1 for decasan). The 0.2% solution of sanguiritrinum had the highest resource of effective action according to AAI data. Synthetic antiseptics had a complete decontaminating effect on most strains after exposure for 5 minutes. Natural antiseptics demonstrated low decontaminating ability, even after exposure for 60 minutes. As a result of a comparative study of solutions containing natural and synthetic antiseptics, the benefits of the latter to microorganisms, which most often caused infections of upper respiratory infections, were established.</p&gt;}, number={2}, journal={Reports of Vinnytsia National Medical University}, author={Kovalchuk, V.P. and Isnyuk, A.S. and Vovk, I.M. and Kishchuk, V.V. and Kovalenko, I.M.}, year={2018}, month={Dec.}, pages={257-262} }
