BIOLOGICAL PROPERTIES OF FILM-FORMATION AND NON-FILM-FORMATION STRAINS OF STAPHYLOCOCCUS EPIDERMIDIS STUDYING

The aim was to select the strains of S. epidermidis, to test their ability to film formation, to study biofilm growth, pathogenicity factors and sensitivity to antibiotics, to investigate the sensitivity to commercial bacteriophage preparations. Methods. The studies used the microbiological and biochemical methods. Results. 122 strains of Staphylococci were identified, 37 of which were identified as S. epidermidis. 20 of these strains were filmforming and 17 – non-film-forming. 15 film-forming and 12 non-film-forming strains of S. epidermidis were sensitive to “Staphylococcal bacteriophage liquid”. All of isolated strains of S. epidermidis were sensitive to quinolones of second generation – ofloxacin and ciprofloxacin. Also, 12 film-forming and 14 non-film-forming strains had sensitivity to gentamicin. Conclusion. Thus, 75% of film-forming strains of S. epidermidis have been sensitive to “Staphylococcal bacteriophage liquid” and 100% strains were susceptible to fluoroquinolones.
