The purpose of this study was to investigate the antimicrobial activity of formulations of F. fomentarius. The antimicrobial efficacy levels of extracts of F. fomentarius prepared from ethanol, water and of various formulations (emulsion, ointment, paste, cream and gel) were determined. For this purpose, the disk diffusion method was used to test the extracts for antimicrobial activity against hospital isolates including Klebsiella pneumoniae, Acinetobacter baumannii, Staphylococcus aureus, vancomycin-resistant enterococci (VRE+), Escherichia coli, Candida krusei, C. albicans, C. tropicalis, C. guilliermondii and C. glabrata. Some standard antibiotics were used for comparison. The ointment formulation (No. 4) showed a good antimicrobial effect on bacteria compared to the antibiotics (9.6 - 16.1 mm.). The extracts were found to be more effective than the antibiotics against Candida species. Formulation No. 4 was considered to be more effective because of the protective nature of its cetyl alcohol and sodium lauryl sulfate (SLS) content. F. fomentarius ethanol extract, F. fomentarius water extract and gel formulation showed similar activity; however, other formulations (emulsion, paste, cream) were generally more effective due to the stabilizing effects of the polymers, oil and alcohols present in their preparations. The findings of this study establish the possibility of discovering new clinically effective antibiotic drugs and could be useful in understanding the relationship between traditional remedies and modern medicines.
