ВЛИЯНИЕ ПЕРФТОРОРГАНИЧЕСКИХ СОЕДИНЕНИЙ НА РОСТ STAPHYLOCOCCUS EPIDERMIDIS

Abstract

In order to analyze the influence of perfluororganic compounds (perfluorodecalin) on growth of Staphylococcus epi-dermidis there was an invitro experiment conducted. During 24hours St.epidermidis cell crop was grown on meat-peptone agar in the Petri dishes: 1.1 water-salt BSS+ solution, 1.2–3,5ml BSS+ solution and 1mg of vancomycin in 0,1ml of 0.9% sodium chloride solution, 1.3 perfluororganic compound, 1.4 the mixture of perfluororganic compound and 1mg of vancomycin in 0,1ml of 0.9% sodium chloride solution. Similarly the Petri dishes were numbered and the second experiment was conducted when the initial Staphilococcusepidermidis concentration was two times reduced. To hold control the pure crop of bacteria was cultivated without adding any additional materials in cups 1.0 and 1.2. No growth of colonies were detected in cups 1,2, 2,2, local absence of growth was found in 1.4, 2,4. In cups 1.1 and 2.1 there was more intensive growth detected and approximately the same intensive growth of crop was found in cups 1.3, 2.3. comparing to the controlled crop. The findings confirm the effectiveness of vancomycin regarding Staphylococcus epidermidis and the possibility of its use together with perfluororganic compounds. This fact can be used in the process of treatment of postoperative endophthalmitis.
