Human saliva microbiome

Here, we present a comparative analysis of the saliva microbiome diversity of three different human groups living under different climatic conditions. We obtained new data from 76 native Alaskans from four different populations, all sampled from the northwest extremity of the North American continent, as well as from ten individuals from Germany. For comparison, we also analyzed previously published data from 66 individuals from three different African populations located near the equator.
