6) In a report to the New York Ophthalmological Society in 1912, Knapp noted that some patients who underwent cataract surgery later manifested clinical signs of dystrophia epithelialis with stromal and epithelial oedema, as described by Fuchs; (7) this is now known as pseudophakic bullous keratopathy (PBK), which is a complication of cataract ...
A biofilm is any group of microorganisms in which cells stick to each other and often also to a surface. These adherent cells become embedded within a slimy extracellular matrix that is composed of extracellular polymeric substances (EPS).
Microbes form a biofilm in response to many factors, which may include cellular recognition of specific or non-specific attachment sites on a surface, nutritional cues, or in some cases, by exposure of planktonic cells to sub-inhibitory concentrations of antibiotics.ormation of a biofilm begins with the attachment of free-floating microorganisms to a surface. These first colonists adhere to the surface initially through weak, reversible adhesion via van der Waals forces.
