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).
For example, erythrocytes and fibrin may accumulate as the biofilm forms. Biofilms on native heart valves provide a clear example of this type of interaction in which bacterial microcolonies of the biofilm develop in a matrix of platelets, fibrin, and EPS (48).iofilms are composed primarily of microbial cells and EPS. EPS may account for 50% to 90% of the total organic carbon of biofilms (38) and can be considered the primary matrix material of the biofilm.
