Abstract

Time-kill and postantifungal effect (PAFE) of amphotericin B, caspofungin, fluconazole, and voriconazole were determined against clinical isolates of Candida guilliermondii, Candida kefyr, and Candida lusitaniae. Azoles displayed fungistatic activity and no measurable PAFE, regardless of the concentration tested. Amphotericin B and caspofungin demonstrated concentration-dependent fungicidal activity, although amphotericin B only produced a significant dose-dependent PAFE against all isolates tested.

摘要

测定了两性霉素B、卡泊芬净、氟康唑和伏立康唑对季也蒙念珠菌、克菲念珠菌和葡萄牙念珠菌临床分离株的时间杀菌和抗真菌后效应(PAFE)。无论测试浓度如何,唑类均表现出抑菌活性且无可测量的PAFE。两性霉素B和卡泊芬净表现出浓度依赖性杀菌活性,尽管两性霉素B仅对所有测试分离株产生显著的剂量依赖性PAFE。
