Escherichia

It is a common bacteria that I think you always know it. I already introduce a probiotic bacteria and a pathogen. For me, I think Escherichia.coli is good also bad bacteria.

WHY?

This bacteria could distributed to five type of infection. No matter what type of E.coli, its always release the enterotoxin, and make the infectious people get dysentery, or hemolytic uremic syndrome.

On the other hands, in many food examined standard, E.coli has be the standard microbes. For potable water, the density of coliform microbes about 1.0 g/ml is the maximum tolerance value.
