生态学( microecology):是20世纪70年代出现的新兴学 科,涉及:进化、生物多样性、物种相互作用、生物修复等. 医学微生物学中所指的微生态( microbiota):在人体(健 康者、患者)中共栖、共生或机会致病性微生物组成的生态( ecology of a microhabitat)o-microbiome 微生态平衡( microeubiosis):在机体中,正常微生物群 的种类和数量处于动态平衡中,不引起疾病。 微生态失衡( microdysbiosis):如宿主因素变化、正常微 生物群种类、数量和位置改变和环境理化因素的影响,微生 态平衡被打破,就会导致疾病,最常见菌群失调。 微生态制剂( Probiotics): Elie Metchnikoff^(1907)提 H"the dependence of the intestinal microbes on the food makes it possible to adopt measures to modify the flora in our bodies and to replace the harmful microbes by useful microbes
