How chronic UTI forms (research from UCL, UK)

This might interest some - here's a description of how chronic UTI forms and invades the cells of the bladder lining.  
This is based on research by the Chronic UTI Group, University College London (UCL), UK, that draws on experiments conducted on mouse models of chronic cystitis, lab work carried out using human bladder cells, or living culture of a human urothelium:

How Chronic UTI Forms

And the proposed treatment for chronic UTI is high dose antibiotics direct into the bladder in the form of micro-bubbles - a relatively new drug delivery system that is also set to be used in treating other conditions (ie in the video).  I suppose the question some people have is does this apply to IC/PBS?  Some leading researchers are saying yes.  That's exciting.
