自然环境中广泛存在着各种微生物,因此,作为人类的体表屏障-皮肤,经常有一些微生物存在,其中一部分由于长期适应的结果,可较长期地寄生在人体的皮肤上,称为皮肤正常微生物群,亦称皮肤正常菌群。正常菌群与其宿主大生物和外环境构成一个生境,这个生境内的微生物,又在大生物一定器官定居,形成微生物定位,皮肤也是其定位之一。这种相互依存的关系构成了一个生态系。生态系中的微生物区系,又分微植物区系和微动物区系。通常主要包括
Because of the widespread presence of various microorganisms in the natural environment, as a surface barrier of human beings, the skin often contains some microbes, some of which, due to long-term adaptation, parasitize human skin over a longer period of time and are called normal skin Microbiome, also known as normal skin flora. Normal flora and its host large living organisms and external environment constitute a habitat, the micro-organisms in this habitat, and living organism in certain organs, the formation of microbial localization, the skin is also one of its positioning. This interdependent relationship constitutes an ecosystem. Microbial flora in the ecosystem, is divided into micro-flora and micro-fauna. Usually include mainly
