摘要:

目的 分析黄连等8种中草药对临床常见耐药与非耐药菌株的体外抑菌活性。方法 选择8种常用抗菌中草药(黄连、金银花、野菊花、连翘、大黄、鱼腥草、芦根和穿心莲) ,采用水提法制备至药物浓度为1 g/mL 。采用肉汤稀释法测定8种中草药对金黄色葡萄球菌(ATCC 29213)、甲氧西林敏感金黄色葡萄球菌(MSSA)、耐甲氧西林金黄色葡萄球菌(MRSA)、大肠埃希菌(ATCC 25922)、产超广谱β-内酰胺酶(ESBL)大肠埃希菌(ATCC 35218)和临床分离的ESBL(-)大肠埃希菌、ESBL(+)大肠埃希菌的最小抑菌浓度(MIC)和最小杀菌浓度(MBC)。结果 黄连、金银花、野菊花、连翘和大黄对金黄色葡萄球菌(ATCC 29213)、MSSA和MRSA的MIC值为7.81~125 mg/mL。黄连和金银花对大肠埃希菌(ATCC 25922)、产ESBL大肠埃希菌(ATCC 35218)、ESBL(-)大肠埃希菌和ESBL(+)大肠埃希菌的MIC值为62.50~250.00 mg/mL。黄连对金黄色葡萄球菌(ATCC 29213)、MSSA和MRSA的MBC值为15.62~62.50 mg/mL,对大肠埃希菌(ATCC 25922)、产ESBL大肠埃希菌(ATCC 35218)、ESBL(-)大肠埃希菌和ESBL(+)大肠埃希菌的MBC值为250.00~500.00 mg/mL。同一种中草药对耐药菌株和非耐药菌株的抑菌活性无明显差异。结论 黄连、金银花、野菊花、连翘和大黄对金黄色葡萄球菌(ATCC 29213)、MSSA和MRSA有较强的抑菌作用;黄连和金银花对大肠埃希菌(ATCC 25922)、产ESBL大肠埃希菌(ATCC 35218)、ESBL(-)大肠埃希菌和ESBL(+)大肠埃希菌也有一定的抑菌作用。

Abstract:

Objective To study the antibacterial activities of 8 kinds of Chinese herbal medicines to clinical common resistant and non-resistant isolates in vitro. Methods Totally,8 kinds of Chinese herbal medicines,including Rhizoma coptidis,Honeysuckle,Chrysanthemum indicum,Forsythia,Rhubarb,Cordate houttuynia,Rhizoma phragmitis and Andrographis paniculata,were selected and extracted with pure water concentrated with1 g/mL. Staphylococcus aureus ATCC 29213,methicillin-sensitive Staphylococcus aureus(MSSA),methicillin-resistant Staphylococcus aureus(MRSA),Escherichia coli ATCC 25922,Escherichia coli ATCC 35218 which produced extended-spectrum beta-lactamase(ESBL),ESBL(-) Escherichia coli and ESBL(+) Escherichia coli were used to determine the minimum inhibitory concentration(MIC) and minimum bactericidal concentration(MBC) in vitro by liquid dilution method. Results The MIC of Rhizoma coptidis,Honeysuckle,Chrysanthemum indicum,Forsythia and Rhubarb to Staphylococcus aureus ATCC 29213,MSSA and MRSA were 7.81-125.00 mg/mL.The MIC of Rhizoma coptidis and Honeysuckle to Escherichia coli ATCC 25922,Escherichia coli ATCC 35218 produced ESBL,ESBL(-) Escherichia coli and ESBL(+) Escherichia coli were 62.5-250.0 mg/mL. The MBC of Rhizoma coptidis to Staphylococcus aureus ATCC 29213,MSSA and MRSA were 15.62-62.50 mg/mL,and the MBC of Rhizoma coptidis to Escherichia coli ATCC 25922 and Escherichia coli ATCC 35218 produced ESBL,ESBL(-) Escherichia coli and ESBL(+) Escherichia coli were 250-500 mg/mL. The bacteriostatic action of the same kind of Chinese herbal medicine to resistant and non-resistant isolates had no statistical significance. Conclusions Rhizoma coptidis,Honeysuckle,Chrysanthemum indicum,Forsythia and Rhubarb have strong bacteriostatic action to Staphylococcus aureus ATCC 29213,MSSA and MRSA. Rhizoma coptidis and Honeysuckle also have certain bacteriostatic action to Escherichia coli ATCC 25922,Escherichia coli ATCC 35218 produced ESBL,ESBL(-)Escherichia coli and ESBL(+) Escherichia coli.
