Description
Summary:The antimicrobial activity of nine crude extracts of three Miconia species (M. albicans, M. rubiginosa and M. stenostachya) was tested against eleven selected microorganisms: Staphylococcus aureus, Staphylococcus saprophyticus, Proteus mirabilis, Escherichia coli, Enterococcus faecalis, Shigella flexneri, Klebsiella pneumoniae, Salmonella sp, Pseudomonas aeruginosa, Streptococcus agalactiae and Candida albicans. The results of the test showed that three extracts had some antimicrobial activity by well diffusion method. The ethanol extracts of Miconia albicans and Miconia rubiginosa were the most active.<br>A atividade antimicrobiana de nove extratos de três espécies de Miconia (M. albicans, M. rubiginosa e M. stenostachya) foi avaliada frente a onze microrganismos: Staphylococcus aureus, Staphylococcus saprophyticus, Proteus mirabilis, Escherichia coli, Enterococcus faecalis, Shigella flexneri, Klebsiella pneumoniae, Salmonella sp, Pseudomonas aeruginosa, Streptococcus agalactiae e Candida albicans. Três destes extratos apresentaram atividade antimicrobiana pelo método de difusão de poço. Os extratos etanólicos de Miconia albicans e Miconia rubiginosa foram os mais ativos.
