No Organism Created De Novo

I would bet you thought all (or even most) bacteria is bad for you? Most
of it isn't. Most of it is symbiotic. Only about 5% of the bacterial
population which lives in your body is pathogenic. The other 95% is
natural and it is necessary. Without it, you would not survive. The
mistake doctors make is too often killing good bacteria and too many
antibiotics and wide-spectrum antibiotics will cause them not to work when
you may need them.

Each of us has about 10 trillion human cells which are outnumbered by 100
trillion bacterial cells.
