Antibacterial Activity of Ethanol Extract of Larch Sponge Fruiting Body

Abstract

Antibiotic resistance in pathogenic bacteria is a worldwide problem. In recent years, there has been increasing interest in the evaluation of plants and fungi with antibacterial activity against various infectious agents. The antibacterial activity of ethanol extract of Laricifomes officinalis (Vill.) Kotl. et Pouzar (Polyporaceae) fruiting body was studied. Activity was assessed using the disk diffusion method. L.officinalis ethanol extract showed high activity against Yersinia pseudotuberculosis, as well as moderate activity against Escherichia coli, Pseudomonas aeruginosa, Salmonella typhimurium, and Staphylococcus aureus. Listeria monocytogenes were not sensitive to ethanol extract of the fruiting body of L.officinalis.
