介绍： This is Scientific American's 60-second Science, I'm Eliene Augenbraun.
Our microbiomes—the tiny organisms that live on us and in us—can influence our health. And a recent study looked at microbiome composition and diversity, depending on where and how we live, given the same latitude and climate across South America:
"We found, in a gradient of urbanization from jungle houses, huts of Amerindian people living traditional lifestyles, all the way to a modern city like Manaus, was differences in microbes from our houses and from our skin and differences in exposure to chemicals."
Microbiologist Maria Gloria Dominguez Bello from Rutgers University.

我们的微生物群——生活在我们体外和体内的微型有机体——可以影响我们的健康。最近的一项研究着眼于微生物群落的组成以及多样性因人类居住地点和生活方式不同而产生的差异，考虑到整个南美的纬度和气候相同：
“我们发现，从过着传统生活的美洲印第安人的丛林住宅和小屋，一直到马瑙斯这样的现代化城市，由于城市化进程存在不同，我们的房屋内和皮肤中的微生物有所差别，我们接触的化学物质也存在差异。”
罗格斯大学的微生物学家玛丽亚·格洛丽亚·多明格斯·贝洛说到。
