The in vitro interactions between bismuth subcitrate and a variety of antimicrobial agents against 12 Campylobacter pyloridis (C. pylori) isolates were studied by the agar dilution checkerboard technique. The combination of bismuth subcitrate with the older quinolone, oxolinic acid, produced synergistic activity against all strains. This observation, however, could not be extended to the (aryl) fluoroquinolones, norfloxacin, ofloxacin, and difloxacin, since synergy was rare or absent when bismuth subcitrate was combined with these antibiotics. Among the other antimicrobial agents tested, rifampin and the beta-lactams frequently showed showed MICs for C. pyloridis similar to those of bismuth subcitrate.
采用琼脂稀释棋盘法研究了枸橼酸铋与多种抗菌剂对12株幽门弯曲菌(幽门螺杆菌)的体外相互作用。枸橼酸铋与较老的喹诺酮类药物奥索利酸联合使用时,对所有菌株均产生协同活性。然而,这一观察结果不能推广到(芳基)氟喹诺酮类药物诺氟沙星、氧氟沙星和双氟沙星,因为枸橼酸铋与这些抗生素联合使用时,协同作用很少或不存在。在测试的其他抗菌剂中,利福平及β-内酰胺类药物对幽门螺杆菌的最低抑菌浓度(MIC)通常与枸橼酸铋相似。
