The in vitro activities of the macrolide antibiotics clarithromycin, 14-hydroxy-clarithromycin, azithromycin, and erythromycin against 19 isolates of Borrelia burgdorferi were investigated. MICs ranged from 0.003 to 0.03 microgram of clarithromycin per ml, 0.007 to 0.03 microgram of 14-hydroxyclarithromycin per ml, 0.003 to 0.03 microgram of azithromycin per ml, and 0.007 to 0.06 microgram of erythromycin per ml. Time-kill studies using the B31 strain of B. burgdorferi demonstrated a > or = 3-log10-unit killing after 72 h with each of the macrolide antibiotics tested in concentrations representing twice the respective MICs.
对大环内酯类抗生素克拉霉素、14-羟基克拉霉素、阿奇霉素和红霉素针对19株伯氏疏螺旋体的体外活性进行了研究。克拉霉素的最低抑菌浓度(MIC)范围为每毫升0.003至0.03微克,14-羟基克拉霉素为每毫升0.007至0.03微克,阿奇霉素为每毫升0.003至0.03微克,红霉素为每毫升0.007至0.06微克。使用伯氏疏螺旋体B31菌株进行的时间-杀菌研究表明,在72小时后,所测试的每种大环内酯类抗生素在两倍于各自MIC的浓度下均有≥3个对数10单位的杀菌效果。
