چکیده مقاله:
Background: Staphylococcus aureus is a pathogenic bacterium that forms biofilms on biotic and abiotic
surfaces. Biofilm formation is important for researchers because it increases the risk of food contamination
in the food industry, increases the pathogenicity of bacteria, and damages the equipment. The main
purpose of this study was to find out the antimicrobial and antibiofilm properties of Oliveria decumbens
essential oil (Od-EO) against Staphylococcus aureus.
Methods: In this study, the antibacterial and anti-biofilm properties of Od-EO were tested against four strong
biofilm producers. S. aureus isolates were obtained from food and humans. The antibacterial properties of
Od-EO on planktonic S. aureus were investigated using the disk diffusion method; further, the minimum
inhibitory concentration (MIC) and minimum bactericidal concentration (MBC) were determined. The
microtiter plate (MTP) method and slime production evaluation were used to assess the inhibitory effect of
Od-EO on S. aureus biofilm formation.
Results: Od-EO indicated strong antimicrobial activity against planktonic S. aureus. After performing
tests related to the anti-biofilm activity of Od-EO, it was found that Od-EO significantly reduced slime
production and thus inhibited biofilm formation.
Conclusions: Od-EO and its components can be used as a new anti-biofilm agent in medical, dental, and
food industry equipment.
