Study suggests intestinal microbe populations vary widely
Identical twins may share appearances, mannerisms, even clothes — but the microbes living in their guts are anything but the same. By comprehensively sequencing microbial genes in the gut, researchers have found that communities of bacteria in adult identical twins differ dramatically. The findings, to appear online during the week of March 29 in the Proceedings of the National Academy of Sciences, give scientists a deeper understanding of what makes one person’s intestinal bacteria different from another’s.
