摘　　要：稀土元素具有多种生物效应,除了对农作物的增产作用外,在医药方面还具有抗菌的作用,近年来,不少学者针对稀土元素的抗菌效应展开了相关的研究。本文介绍了稀土在抗菌领域的研究及应用,包括稀土化合物对微生物生长的Hormesis效应、稀土化合物与抗生素的协同作用、稀土配合物的合成、以及稀土在抗菌材料上的应用等几个方面的内容,并对稀土化合物及其配合物的抗菌机理进行了探讨,最后,展望了稀土化合物及配合物在抗菌领域的应用前景及研究重要性。Rare-earth elements are characterized with their biological effects on some organisms. Besides the increase production effect in agriculture, rare-earth elements also have antimicrobial effect in clinic. Recently, the antimicrobial effect and mechanism of rare-earth elements are under investigation by some scholars. This paper summarized the antimicrobial activity and application of rare earth compounds and complexes, including Hormesis effect of rare-earth elements to some microorganism, synergistic effect of rare-earth elements with antibiotic, synthesis of some rare earth complexes, and the application of rare earth compounds in antibacterial materials. Then the antimicrobial mechanism of rare earth compounds and complexes have been discussed. At last, the application for foreground and essentiality of rare earth compounds and complexes in antimicrobial field will be expected.
