yeah, I know, I just didn't know how to put it clearly! Of course they're different organisms! Also, we have about a billion E.coli living in our intestine, producing vitamin K. Without E.coli, our blood wouldn't clot, and we'd bleed to death. As you know, it's only dangerous if it escapes the gastro-intestinal tract!
