In recent decades, Candida albicans have been the main etiological agent of life-threatening invasive infections, characterized by various mechanisms of resistance to commonly used antifungals. One of the strategies to fight Candida infections may be the use of an electromagnetic field. In this study, we examined the influence of the alternating magnetic field of 50 Hz on the cells of C. albicans. We checked the impact of the alternating magnetic field of 50 Hz on the viability, filamentation and sensitivity to fluconazole and amphotericin B of two, differing in hydrophobicity, strains of C. albicans, CAF2-1 and CAF 4-2. Our results indicate that using the alternating magnetic field of 50 Hz reduces the growth of C. albicans. Interestingly, it presents a stronger effect on the hydrophobic strain CAF4-2 than on the hydrophilic CAF2-1. The applied electromagnetic field also affects the permeabilization of the cell membrane. However, it does not inhibit the transformation from yeast to hyphal forms. AMF is more effective in combination with fluconazole rather than amphotericin B. Our findings confirm the hypothesis that the application of the alternating magnetic field of 50 Hz in antifungal therapy may arise as a new option to support the treatment of Candida infections.
近几十年来,白色念珠菌一直是威胁生命的侵袭性感染的主要病原体,其具有各种对抗常用抗真菌药物的耐药机制。对抗念珠菌感染的策略之一可能是利用电磁场。在这项研究中,我们研究了 50Hz 交变磁场对白色念珠菌细胞的影响。我们检查了 50Hz 交变磁场对两种不同疏水性的白色念珠菌菌株 CAF2-1 和 CAF4-2 的活力、丝状形成和对氟康唑和两性霉素 B 的敏感性的影响。我们的结果表明,使用 50Hz 的交变磁场会降低白色念珠菌的生长。有趣的是,它对疏水性 CAF4-2 菌株的影响比亲水性 CAF2-1 菌株更强。施加的电磁场还会影响细胞膜的通透性。然而,它不会抑制酵母向菌丝形式的转化。AMF 与氟康唑联合使用比与两性霉素 B 联合使用更有效。我们的研究结果证实了这样一种假设,即在抗真菌治疗中应用 50Hz 的交变磁场可能会成为支持念珠菌感染治疗的新选择。
