Hi, Wendy:
I am talking about all of them--the good ones and the bad. Some bacteria have worked out an agreement with our bodies and "help" us digest food or make vitC or B12 but we really do not need them to survive...or DO we? Have we become reliant upon them for our life?
As a taker of broad-spectrum antibiotics, I have to understand that I am wiping out good bacteria along with the bad ones and some of these good bacteria displace really bad things like C. albicans and C. difficile, so overgrowths of these--dysbiosis or colitis or candidiasis--are part of the territory, but I wish we could also eliminate these creatures--just wipe the slate clean and start over, implanting just the stuff we want. Klebsiella is considered one of the beneficial bacteria in our guts, but when displaced into our lungs it becomes a really bad pneumonia and who knows what other mischief it gets up to?
I'm for eviction and asking questions later! I'll take the risks of not having the germs and finding out what digestive difficulties might ensue. But like I said, I don't really know whether the 'boy in the bubble' or others who are so immunocompromised have the normal complement of intestinal flora or not.
That's a question for the biology experts,
Best to You,
John
