人体的菌群一个健康成人所携带的细菌相当于人体细胞的10倍，而这些微生物在长期的进化过程中和人形成共生关系，许多微生物对人不仅无害，而且有益。Thebacteriacarriedbyahealthyadultareequivalentto10timesthesizeofhumancells,andthesemicroorganismshaveformedsymbioticrelationshipswithhumansoveralongperiodofevolution.Manymicroorganismsarenotonlyharmlesstohumans,butalsobeneficial.Humanmicrobiota你拥有多少细菌，知道吗？Doyouknowhowmanybacteriayouhave?

正常菌群Normalmicrobiota指人体的体表及与外界相通的腔道上有不同种类和数量的，在正常情况下对人体无害甚至有益的微生物群。Therearedifferenttypesandquantitiesofmicrobialcommunitiesonthesurfaceofthehumanbodyandthemucousmembranesoftheexternalcommunicationchannels,whichareharmlessorevenbeneficialtothehumanbodyundernormalcircumstances.概念Concept
