Among gut microbes, strains, not just species, matter

Sophisticated genomic techniques now allow scientists to estimate the strains, not just the species, in samples of the human gut's microbe collection. Differences in the strains of microorganisms present might account for the variable influence the gut's microbe community has on human health and disease. Understanding the effects of various strain combinations on such functions as metabolism, immunity and drug reactions might suggest ways to manipulate the gut microbiome to improve health.
