Thanks Shroom. I wish I had more of a Science background so that I could pursue biofilms. They seem to be integral to infections in general. Apparently they are very common in infections around medical devices and make treating the infections very difficult. Getting rid of my biofilm was a game changer in eliminating my parasites. I've come to believe that the parasites cooperate with each other and other pathogens to enhance their survival and our ill health.
I spoke with a hospital infectious disease control specialist who theorized that legionnaire's disease was in the hospital plumbing pipes in a biofilm. Knocked loose by a water main break, it killed a susceptible patient. They started using special systems to eliminate biofilms in the water supply thereafter.
Lots of videos on biofilms on YouTube.
