In a study published last month in Genome Biology, a team of Harvard-led researchers used a recently developed technique combining state-of-the-art genetic sequencing and analysis to get an up-close look at the mouth and the ecosystem of microbial communities living within it, including those that cannot be cultured.
The report details an impressive amount of variability in the bacterial subpopulations living on the tongue, inner cheek, and teeth beyond what had been previously documented. It shines a spotlight on how bacterial communities divide up habitats and pattern themselves. Read more …
