细菌生物被膜 ,又称菌膜 (bacterialbiofilm )是单一或多种细菌在不利于其生长的环境下 ,产生藻酸盐多糖使细菌相互黏连形成膜状物附于病灶的表面或导管内。这是细菌为适应环境维持自身生命所发生的形态学的变化 ,从而增强了细菌对外环境的抵抗力。这也成为一些细菌对抗生素产 Bacterial biofilms, also known as bacterial biofilm, are bacteria or bacteria that, in an environment that is detrimental to their growth, produce alginate polysaccharides that attach bacteria to each other to form membranes attached to the surface or duct of the lesion. This is the bacteria to adapt to the environment to maintain their own life by the morphological changes, thereby enhancing the resistance of bacteria to the external environment. It has also become a bacterium for antibiotic production
