How biofilms form
WebInterestingly, it has also been found that conjugative plasmids influence bacteria to form biofilms, suggesting that medically relevant plasmid-bearing strains may preferentially form a biofilm and thus may increase the chance of biofilm infection and the risk of the spread of virulence factors. 123 Gene transfer has also been shown to induce an enhanced … Webnent organisms of these biofilms produce urease, which hydrolyzes the urea in the patient’s urine to ammonium hydroxide. The elevated pH that results at the biofilm-urine interface results in precipitation of minerals such as struvite and hydroxyapatite. These mineral-containing biofilms form encrustations that may completely block the inner ...
