过去十年间,广谱及有效新杀菌剂氟喹诺酮类已发展成当前抗化疗方面一主要药物。氟喹诺酮类的抗菌及药代动力学特点,使其治疗胆道感染(BTI)方面疗效显著。抗生素治疗BTI疗效的决定因素,首先,取决于对致BTI常见菌的抗菌谱,胆汁中杀菌活性及药代动力学特点,尤其是组织分布及胆汁排泄程度。70%以上的需氧菌是由大肠杆菌、克雷伯氏菌属、变形菌属及粪肠球菌组成。而50%感染主要病原菌包括,大肠杆菌或部分
Over the past decade, fluoroquinolones, a broad-spectrum and potent new bactericide, have emerged as a leading drug in the area of chemotherapy. Fluoroquinolones antibacterial and pharmacokinetic characteristics, so that the treatment of biliary tract infections (BTI) has a significant effect. The determinants of antibiotic treatment of BTI depend primarily on the antibacterial spectrum of the common BTI-causing bacteria, the bactericidal and pharmacokinetic characteristics of the bile, especially the tissue distribution and extent of bile excretion. More than 70% of the aerobic bacteria is composed of Escherichia coli, Klebsiella, Proteus and Enterococcus faecalis. However, 50% of the major pathogens that are infected include Escherichia coli or some of them
