摘要:

背景:纳米氧化锌作为无机抗菌剂,与有机杀菌剂的抗菌机制明显不同。
目的:探讨纳米氧化锌对白色念珠菌等真菌的抗菌作用。
方法:分别配制成100,75,50,25,10 g/L的纳米氧化锌与普通氧化锌悬浊液,以生理盐水作为阴性对照,采用KB纸片扩散法将30 μL不同浓度悬浊液分别作用于白色念珠菌,将培养平板上置于37 ℃恒温箱培养24 h观察并测量抑菌圈大小。
结果与讨论:随着纳米氧化锌浓度的提高,对白色念珠菌的抑制作用逐渐增强,抑菌圈直径逐渐增大。普通氧化锌的无明显抑菌作用。证实纳米氧化锌能够抑制白色念珠菌等真菌的生长。

Abstract:

BACKGROUND: As an inorganic antibacterial agent, nano zinc oxide has different antibacterial mechanisms from organic fungicides.
OBJECTIVE: To explore the antibacterial effects of nano zinc oxide on the fungus, such as Candida albicans.
METHODS: Nano zinc oxide and zinc oxide were prepared as the suspension with concentrations of 100, 75, 50, 25 and 10 g/L respectively. Normal saline served as a negative control. 30 μL suspension with different concentrations was acted on Candida albicans by using Kirby-Bauer disk diffusion method. The culture plate was cultured at a 37 ℃ incubator for 24 hours. The size of inhibition zone was observed and measured.
RESULTS AND CONCLUSION: With the increased concentration of nano zinc oxide, the antibacterial effect on Candida albicans was enhanced gradually, and the diameter of inhibition zone was enhanced. There were no obvious antibacterial effects of zinc oxide on Candida albicans. These findings suggest that nano zinc oxide can inhibit the growth of Candida albicans.
