That whole mix is just like a tiny, miniature zoo. You have them growing on and in you and I have them growing in me. Every living being has this microbiome world living on and inside of them.
It is when we have the nasty ones like I mentioned above during a time we have suppressed immune systems that THOSE BAD BUGS displace the benign and beneficial microbes. Using a grass yard analogy, that is like when the dandelions and other “bad weeds” choke out the “good grass.”
When this happens in a hospital. The accepted response is to totally disinfect a contaminated room.
So the question becomes: What happens when we remove all bacteria, viruses, microbes from an environment?
Picture that we remove the plants from our yard, including both the weeds and the grass. Every last living weed, blade of grass, everything……GONE …..stripped from the soil. Nothing is left but bare soil.
It is great news that there are not any weeds in the yard! (maybe)
In the absence of plants, any seed that comes into the yard begins to grow. It the neighbor’s yard has weeds, the yard fills with weeds. In a hospital environment, the microbes that begin to repopulate the clean area can as easily be MRSA, C-diff, or any other “bad” contaminant that is in an adjacent area that was not disinfected.
This is where the studies of useful probiotics enter the picture. If a mix of the benign and beneficial organisms are introduced to the environment they will grow in the hospital instead of the “bad” contaminants. studies are underway that are suggesting that the best long term solution to serious biological contaminants is to disinfect and then introduce good stuff to start growing such as a controlled mix of Probiotics.
