Another thing that has me wondering… why would Escherichia coli (e. coli) be listed under Beneficial Bacteria on Nicholas’s Microbiology results?  Anytime I’ve ever heard of e. coli, it hasn’t been good.

Well, from what I understand, there are different strains of this bacteria.  The one I am referring to is a common bowel bacteria that we all carry and is apparently harmless. 

 My next question would be – can this ever become a problem?  Does this mutate?
