I was aware that certain bacteria use biofilm as one of their many strategies to evade immune and antibiotics attack. From personal experience, I was aware of the importance of addressing biofilm when on antibiotics. Antibiotics stopped working for me years ago and so did my recovery. That was until I started tackling biofilm and from there I never looked back. I would have never recovered without that change in therapy. However, it was only recently that I became aware that biofilm may be an issue with viruses, yeast/candida and possibly parasites. Here's an article on a recently discovered biofilm forming retrovirus. http://www.sciencedaily.com/releases/2010/02/100205115946.htm And a couple of articles I read about yeast and biofilm http://jcm.asm.org/cgi/content/short/41/7/2961 http://www.ncbi.nlm.nih.gov/pubmed/19898545 There are plenty of scientific articles on bacterial biofilm and chronic infections. Biofilm is known to make microbes resistant to therapy. So I wondered whether biofilm may also be an issue where response to treatment is poor or when people need to make chronic use of anti-virals or anti-fungals in order to feel better. Or put it another way, would known anti-biofilm agents (that work against bacterial biofilm) make anti-virals and anti-fungals drugs more effective?
