The anti-infective activities of plant-derived secondary metabolites are under investigation in recent years due to accelerating antibacterial and antifungal resistance rates of microorganisms. In this study, antimicrobial activity of Calliergonella cuspidata, Dicranum polysetum and Hypnum cupressiforme were screened against Bacillus subtilis ATCC 6633, Candida albicans ATCC 10231, Enterobacter aerogenes ATCC13048, Enterococcus durans, Enterococcus faecalis ATCC 29212, Enterococcus faecium, Escherichia coli ATCC 25922, Escherichia coli CFAI, Klebsiella pneumoniae, Listeria monocytogenes ATCC 7644, Salmonella enteritidis ATCC 13075, Salmonella infantis, Salmonella kentucky, Salmonella typhimurium SL 1344, Staphylococcus aureus ATCC 25923, Staphylococcus carnosus MC1.B, Staphylococcus epidermidis DSMZ 20044 and Streptococcus agalactiae DSMZ 6784 by using the disk diffusion method. It is observed that ethanolic extract of the moss samples have antimicrobial activity against several gram positive and gram negative microorganisms tested. But antimicrobial activity of
D. polysetum is notable especially against S. carnosus. These results are the very first data about the antimicrobial activity of C. cuspidata and D. polysetum.
