Effect of Quorum Sensing Molecule Farnesol on Mixed Biofilms of Candida albicans and Staphylococcus aureusMethicillin-resistant/sensitive S. aureusBiofilms of C. albicans-MSSA/MRSAResistanceFarnesolEnhancing EffectCell ViabilityMicroscopyThis article belongs to the Special Issue Microbial Biofilms, Antimicrobials, and Virulence Determinants.The natural bioactive molecule farnesol (FAR) is widely studied mainly for its antibiofilm and antimicrobial properties. In addition, it increases the effectiveness of some antimicrobial substances, which makes it interesting for the development of combined therapy. In the present work, the effect of FAR either alone or in combination with oxacillin (OXA) on mixed biofilms formed by clinically relevant pathogens, Candida albicans and Staphylococcus aureus, was studied. S. aureus isolates used for biofilm formation originated from blood cultures and central venous catheters (CVC) were characterized in terms of antimicrobial resistance. The minimal biofilm inhibitory concentration (MBIC50) for FAR of 48 h mixed biofilms formed by the C. albicans and methicillin-sensitive S. aureus (MSSA) was determined to be 125 M, and for the mixed biofilms with methicillin-resistant S. aureus (MRSA) was determined to be 250 M. Treatment of mixed biofilms with OXA (2 mg/mL) showed 4% inhibition; however, the combination of OXA (2 mg/mL) and FAR (300 M) resulted in 80% inhibition of biofilms. In addition, planktonic cells of S. aureus exhibited an increased susceptibility to OXA, cefoxitin and kanamycin in the presence of FAR (150 and 300 M). Scanning electron microscopy (SEM) micrographs confirmed patchy biofilm and lack of candidal hyphae in the samples treated with FAR and FAR/OXA in comparison to control and mixed biofilms treated only with OXA. Intriguingly, in a pilot experiment using fluorescence in situ hybridization (FISH), considerable differences in activity (as indicated by ribosome content) of staphylococcal cells were detected. While the activity rate of the staphylococci in mixed biofilms treated with FAR was high, no FISH-positive signal for staphylococcal cells was found in the biofilm treated with FAR/OXA.This research was funded by the Slovak Research and Development Agency under contracts of SK-PT-18-0006 as part of the Bilateral Cooperation Program (2019–2022), APVV-21-0302 and APVV-18-0075.
