| 摘 要： | 目的 了解不同含量的铜、锌、锡金属板(1号、2号、3号)对不同种细菌的抑制作用及比较.方法 取1ml不同浓度菌悬液混入4ml 56℃营养琼脂液中,浇注到1～3号金属板和阳性对照中,浇注量为1ml/板,37℃孵育24～72h,观察细菌生长情况.结果 紫铜和黄铜对金黄色葡萄球菌(ATCC25923)、大肠埃希菌(ATCC25922)和临床分离菌株抑菌能力较好,均无细菌生长,青铜次之;紫铜对白假丝酵母菌有很好的抑茵作用,均无细菌生长,青铜和黄铜对白假丝酵母茵抑菌效果较差,3种金属板对铜绿假单胞菌抑菌效果均较差.结论 不同含量的铜、锌、锡金属板因各自成分不同,对不同种细菌的抑制作用也各不相同,可为医疗消毒领域提供参考.

| Abstract: | Objective To observe bacteriostatic effect of metal board with different concentrations of Cu2+,Zn2+ and Sn2+(corresponding to metal board 1,2 and 3 respectively).Methods After mixing 1 ml bacterial suspension with 4 ml agar solution(56℃) evenly and completely,then 1 ml mixture was poured into the tests and control metal board respectively.The boards were incubated at 37℃ for 24-72h.Results Metal board 1 and 3 showed higher antimicrobic properties for Staphylococcus aureus and Escherichia coli.Metal board 1 showed higher antimicrobic properties for Candida albicans.Metal board 1-3 showed low antimicrobic properties for Pseudomonas aeruginosa.Conclusion The metal boards with different concentrations of Cu2+,Zn2+ and Sn2+ have different antimicrobic properties for different bacterium.It provided a reference for disinfection in medical field. |
