AIM: 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 li- chens was determinedby 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 Pseudo- monas 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 per- spective source of antibacterial substances, effective against antibiotics resistant staphyloco- cci, streptococci and S. maltophilia strains.
