Effect of Berberine and Some Antibiotics on the Growth of Microorganisms

벨베린과 수종 항생제가 세균발육에 미치는 영향

The combined effect of berberine isolated from the bark of Phellodendron amurense and some antibiotics was evaluated in order to measure the antibiotic activities. In this study, in the presence of streptomycin, tetracycline, cephradine as antibiotics, Staphylococcus aureus, Escherichia coli, Shigella sonnei as microorganisms were grown in an Automated Microbiology System. In case of Staphylococus aureus, combination with berberine and cephardine resulted in the strongest synergistic activity and in case of Escherichia coli and Shigella sonnei, combination with berberine and streptomycin resulted in the strongest synergistic activity. The combination with berberine and antibiotics increased the antibiotic activities, thereby showing a synergistic action.
