每个地区每个人的皮肤都带有独有的、稳定的、无害微生物生态学。任何皮肤接触就交换了一些这种细菌;入侵的这些细菌顽固地暂留在人的皮肤上,直到最后被适应性较好的皮肤上的本身细菌所消灭。科学家现在正利用这些接触的带菌指印来研究人类的交往。例如:经常握手的一群人就会共有寄
Everyone’s skin in each region carries a unique, stable, harmless microbial ecology. Any contact with the skin exchanges some of these bacteria; the invading bacteria stubbornly persist on human skin until it is finally destroyed by its own bacteria on the well-adapted skin. Scientists are now using the contact fingerprints to study human interaction. For example: a group of people who often shake hands will be shared
