They live in our mouth, on our skin and mostly in our digestive tract. There are up to a thousand different varieties, and their total number, some 100 trillion, is many times greater than the total number of human cells in the body. Luckily bacterial cells are much smaller than human cells, their total weight is only about three pounds, so we don’t look like bacteria.</p> Mon, 27 Nov 2017 17:10:55 +0000 Joe Schwarcz PhD 6832 at /oss
