摘要
研究不同种类亚抑菌浓度抗生素与细菌释放内毒素的关系。实验选择临床常用的六种抗生素(哌拉西林、亚胺培南 /西司他丁、头孢他啶、环丙沙星、阿米卡星和头孢哌酮 /舒巴坦 ) ,以 0 .5×MIC药物浓度分别作用于铜绿假单胞菌 PA10 3和大肠埃希氏菌 V5 17。检验抗生素作用后细菌菌量、形态学变化及培养液中游离内毒素水平。结果不同种类抗生素作用后能使细菌形态发生改变 ,同时能不同程度引发细菌释放内毒素。其中哌拉西林、环丙沙星和头孢他啶引发细菌释放的内毒素最多 ,其次为阿米卡星 ,亚胺培南 /西司他丁和头孢哌酮 /舒巴坦引发细菌释放的内毒素最少。结论 :不同种类抗生素可以引发细菌释放内毒素。提示临床应用抗生素 ,除考虑药敏外 ,还应考虑抗生素引发细菌释放内毒素的能力 ,抗生素处于亚抑菌浓度时尤需引起重视。
