"Even for many doctors specialising in urology or gynaecology, the idea of biofilm infections is relatively new."
Proving that doctors only read old journals and research and do not listen to their patients. The idea of biofilm has been discussed on SCI forums for years and I see general acceptance of the idea. More often it is just called 'colonization'. The discussed remedy of more of the same, meaning antibiotics, sounds to me like grasping at straws. Also, the link to bladder and kidney stones is important and not mentioned in the article. Still it is a useful article for those getting chronic UTIs even though they do not need catheterization.
For SCId people like us I suspect catheterization confuses both us and our doctors even more because we, or they, can assume infection is being repeatedly reintroduced, which may play a role but does not settle the question.
Certain fruit juices help against biofilm. www.mdpi.com/1420-3049/22/8/1256/htm Phenolic Compounds Contained in Little-known Wild Fruits as Antiadhesive Agents Against the Beverage-Spoiling Bacteria Asaia spp.
Received: 6 July 2017 / Accepted: 23 July 2017 / Published: 28 July 2017 Abstract: The aim of the study was to evaluate antioxidant activity and total phenolic content of juice from three different types of fruits: elderberry (Sambucus nigra), lingonberry (Vaccinium vitis-idaea) and cornelian cherry (Cornus mas), and their action against adhesion of bacterial strains of Asaia lannensis and Asaia bogorensis isolated from spoiled soft drinks. ...
...The strongest anti-adhesive properties were noted for elderberry juice, which inhibited the adhesion of Asaia spp. to the polystyrene carrier by 87% on average. Slightly weaker properties were noted for lingonberry juice (85%), and cornelian cherry (77%). Considering the species of tested bacteria, tested juices were characterized by a stronger anti-adhesive activity in relation to A. lannensis, inhibiting the attachment of the cells by 75%.
