[ Method ] Staphylococcus aureus CMCC29178 and Escherichia coli ATCC25922 reference strains were used for the determination of minimal inhibitory concentration (MIC) and fractional inhibitory concentration (FIC) index using the broth microdilution method. [ Result] The aqueous extracts of Herba paederiae and Kalimeris indica ( L. ) Sch. -Bip had certain antibacterial effects on Staphylococcus aureus and Eschedchia coli. Synergistic effects or additive effects at different degrees were observed when they were applied with the commonly used antibiotics. [ Conclusion] Water extraction can be widely used to primarily screen medicinal plants with antibacterial activity.展开更多
