Aktywność olejku szałwiowego wobec bakterii beztlenowych

*Anna Kędzia

Summary
A total of 63 strains of anaerobic bacteria isolated from samples obtained from patients with infections of oral cavity and upper respiratory tract were tested. The susceptibility (MIC) anaerobic bacteria to sage essential oil was determined by means of a plate dilution technique in Brucella Agar with 5% defibrinated sheep blood. The inoculum containing 10⁶ cfu per spot was seeded with the Steers inoculator upon the surface of agar. Incubation was performed in anaerobic conditions at 37°C in anaerobic jars. After 48 hours the lowest concentration of sage essential oils inhibiting the growth of anaerobic bacteria was read. The results of these investigations indicated, that strains belonging to the genera of Prevotella (69%), Porphyromonas (50%), Finegoldia (100%) and Ruminococcus (100%) were the most sensitive to sage essential oil. The strains of Bacteroides and Gram-positive rods were less sensitive (29% and 33% respectively). The strains of Gram-negative anaerobic cocci belonging to genera Veillonella were the least sensitive to essential oil. The growth of these strains were inhibited in concentrations from 1 to 3 mg/ml.
