Bacterial cells in the body outnumber human cells by a factor of 10 to 1. Yet only recently have researchers begun to
elucidate the beneficial roles these microbes play in fostering health.
Some of these bacteria possess genes that encode for beneficial compounds that the body cannot make on its own. Other
bacteria seem to train the body not to overreact to outside threats.
Advances in computing and gene sequencing are allowing investigators to create a detailed catalogue of all the bacterial
genes that make up this so-called microbiome.
Unfortunately, the inadvertent destruction of beneficial microbes by the use of antibiotics, among other things, may be
leading to an increase in autoimmune disorders and obesity.
