We have bacteria on us, on our desks, in our digestive system, all around our house......they are here to stay... A research group at UGA in Athens, Georgia estimates the global population at around five million trillion trillion or 5,000,000,000,000,000,000,000,000,000,000 with 92-92% in the subsurface of soils. Just a few cause human disease and some benefit us. Recently, other researchers discovered at least 182 species of bacteria from skin swabs from the forearms of six people....they extrapolated an estimate of at least 250 species in our skin, a veritable zoo!
