- Abstract
The formation of microbial biofilms on a medical material is a dangerous fact because of the insensitiveness of microorganisms in conglomarates to antibiotics and their resistance to environmental factors. The aim of the work was to study the ability of A. calcoaceticus IMV B-7241 surfactants with various degrees of purification to prevent the adhesion of microorganisms on the surface of the medical material. It was stated that different preparations of Acinetobacter calcoaceticus ??V ?-7241 with various degrees of purification retarded Candida albicans D-6, Bacillus subtilis ??-2 and Escherichia coli ?EM-1 adhesion on the surface of prosthetic material: acryl material (teeth) and silicone base. It was also proved that the degree of cell adhesion of studied microorganisms depended on the type of material, microorganism and concentration of biosurfactants in preparations. In some cases lower concentration was even more effective. The preparation of surface-active substances (0.36 mg/ml) reduced the adhesion on the silicone base: C. albicans D-6 by 85, B. subtilis BT-2 - 91.2; the acrylic material C. albicans D-6 - 96.8, B. subtilis BT-2 - 97.5 %. The same concentration reduced the adhesion of E. coli IEM- 1 on the acrylic material by 88.6, on the silicone basis (0.0036 mg/ml) by 93.6 %. These results indicated the possibility of biosurfactant introduction in dentistry as antiadhesive preparations that prevent bacterial biofilm formation on a surface of dentures and as a result its demage.
