摘要

微生物生命聚集在一种自产的胞外多糖(EPS)基质上,相互共存,抵御外界攻击和不利的环境条件,这是生物膜的最佳描述。这个微生物群落为其成员提供了许多生存和营养方面的好处,同时也预示着巨大的生态和健康问题。生物膜几乎可以在任何表面形成;陆地、水生、植物、动物以及医疗设备和植入物。生物膜从亲本茎分散的能力确保了在其生态位内的持续生存和传播。因此,生物膜生物在其浮游形态上具有独特的生存机制,并有助于我们理解感染性微生物的致病性机制。这篇综述强调了对生物膜的理解的趋势,并强调了它们的健康意义。

Factors Associated with Biofilm Persistence on Different Surfaces, Spread and Pathogenicity
The conglomeration of microbial life on a self-produced extracellular polysaccharide (EPS) matrix for mutual co-existence and protection against external aggression and adverse environmental conditions best describe biofilms. This community of microorganisms confers a number of survival and nutritional benefits to members while at the same time portend great ecological and health concern. Biofilms can form on virtually any surface; terrestrial, aquatic, plants, animals and on medical devices and implants. The ability of biofilms to disperse from the parental stalk ensures continuous survival and spread within their ecological niche. Biofilm organisms therefore possess unique survival mechanisms over their plancktonic form and have contributed to our understanding of the mechanisms of pathogenicity of infectious microorganisms. This review highlights trends in the understanding of biofilms and emphasized their health significance.
