Abstract

Due to the increasing number of Candida albicans' infections and the resistance of this pathogenic fungus to drugs, new therapeutic strategies are sought. One of such strategies may be the use of static magnetic field (SMF). C. albicans cultures were subjected to static magnetic field of the induction 0.5 T in the presence of fluconazole and amphotericin B. We identified a reduction of C. albicans hyphal length. Also, a statistically significant additional effect on the viability of C. albicans was revealed when SMF was combined with the antimycotic drug amphotericin B. The synergistic effect of this antimycotic and SMF may be due to the fact that amphotericin B binds to ergosterol in plasma membrane and SMF similarly to MF could influence domain orientation in plasma membrane (PM).

摘要

由于白色念珠菌感染的数量不断增加,以及这种病原真菌对药物的耐药性,人们正在寻求新的治疗策略。其中一种策略可能是利用静磁场(SMF)。在氟康唑和两性霉素 B 的存在下,将白色念珠菌培养物置于磁感应强度为 0.5T 的静磁场中。我们发现白色念珠菌菌丝长度缩短。此外,当 SMF 与抗真菌药物两性霉素 B 联合使用时,对白色念珠菌的存活能力有明显的附加影响。这种抗真菌药物和 SMF 的协同作用可能是由于两性霉素 B 与质膜中的麦角固醇结合,而 SMF 类似于 MF 可以影响质膜(PM)中的域取向。
