Even worse, bacterial biofilms (bacterial cells plus slime) are very resistant to antibiotics and biocides.
But at the darker end of the scale, biofilms can form infection-inducing layers on implanted medical devices and cause deadly lung infections in cystic fibrosis patients.
This study offers new perspectives to clarifying our understanding of the specific phenotypes of bacterial biofilms and thus enables control of their development.
Destroying biofilm sections in the exponential growth phase does not destroy bacteria in the biofilm that are in the static and stationary growth phases.
While some of the bacteria present feed off of oral nutrients supplied by the host (such as sugars), others within the plaque rely upon nutrients produced by other bacteria within the biofilm .
