Abstract: Antibacterial and antifungal activities of extracts obtained from M. alysson, R. raetam were tested using a solid medium technique. We showed that the petroleum ether extract of M. alysson had a Minimum Inhibitory Concentration (MIC) varied from 128 to 2000 μg mL-1 against different Enterobacteriaceae and antifungal activity against Candida glabrata, Candida albicans, Candida parapsilosis and Candida kreusei with a MIC of 256 μg mL-1. The ethyl acetate extract of R. raetam showed the best activity against Gram positive organisms with MICs of 128 to 256 μg mL-1 against methicillin resistant Staphylococcus aureus but low activity against the different Candida species.
