中文摘要:
      :采用K-B 纸片法检测山莓叶乙醇提取物(RE)、抗生素对 3种致病菌(大肠杆菌、痢疾志贺氏菌、 沙门氏菌)的最低抑菌浓度(MIC),再将 RE 与抗生素联合使用,用棋盘法与K-B 纸片法相结合进行抑菌效果 评价。结果显示:对于大肠杆菌、痢疾志贺氏菌、沙门氏菌,RE的MIC分别为6.250、6.250、3.125…mg/mL;RE与 金霉素协同使用的分级抑菌浓度(FIC)最小值分别为 0.313、0.375 和 0.313,协同抑菌效果最好的配比分别为 1/8MIC1 ∶1/2MIC2、1/4MIC1 ∶1/2MIC2 和1/8MIC1 ∶1/2MIC2;RE与净球散协同的FIC 最小值分别为 0.375、0.313和 0.375,协同抑菌效果最好的配比分别为1/4MIC1 ∶1/2MIC2、1/8MIC1 ∶1/2MIC2 和1/4MIC1 ∶1/2MIC2。大肠杆菌、痢疾志 贺氏菌和沙门氏菌山莓叶乙醇提取物的浓度控制在1/4~1/8MIC1,金霉素和净球散浓度均为1/2MIC2,均有较强的 协同抑菌效果。
英文摘要:
      The minimum inhibitory concentration(MIC)of RE and antibiotics on Escherichia coli,Shigella dysenteroae,and Salmonella were measured by Kirby-Bauer text(K-B). Then Rubus corchorifolius L.f leaves(RE) was used to combine with antibiotics. Fractional inhibitory concentration(FIC) was measured by checkerboard microevolutio and K-B method. The results showed that E. coli,S. dysenteroae and Salmonella were used as microbial strains to test the antibacterial activity,the MICs of RE were 6.250 mg/mL,6.250 mg/mL,3.125 mg/mL,respectively. The minimum FICs of combined use of RE and aureomycin were 0.313,0.375,0.313,and the best ratios were 1/8MIC1∶1/2MIC2, 1/4MIC1∶1/2MIC2,1/8MIC1∶1/2MIC2,respectively. The minimum FICs of combined use of RE and Jingqiusan were 0.375, 0.313,0.375,and the best ratios were respectively. When theconcentration of RE was 1/4~1/8MIC1,and the concentrations of aureomycin and Jingqiusan were 1/2MIC2,the synergistic antimicrobial effects on E. coli,S. dysenteroae and Salmonella were strong.
