Study spectrum and expressiveness of antibacterial and antifungal properties oflichen extracts. Materials and methods. Antimicrobial activity of acetone extracts from Hypogymnia physodes, Xanthoria parietina, Evernia prunastri, Ramalina pollinaria, Cladonia arbuscula lichens was determined by micro-dilution methods in broth for 4 - 500 mcg/ml concentrations against 13 strains from ATCC collection and 6 clinical isolates. Results. High antibacterial activity of H. physodes and C. arbuscular extracts against staphylococci and enterococci was detected (MIC 31 - 62 mcg/ml). Antimicrobial activity against enterobacteria and Pseudomonas aeruginosa was absent for all the extracts. E.prunastri, H.physodes and C arbuscula extracts were active against Stenotrophomonas maltophilia strains (MIC 250 - 500 mcg/ml). Antifungal activity (MIC 500 mcg/ml for 4 Candida strains) was only detected for the E. prunastri extract. Conclusion. H.physodes and C. arbuscula lichens can be examined as a perspective source of antibacterial substances, effective against antibiotics resistant staphylococci, streptococci and S. maltophilia strains.Stenotrophomonas maltophilialichensextractsantibacterial activity.
