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).
Other cell surface properties may also facilitate attachment. Several studies have shown that treatment of adsorbed cells with proteolytic enzymes caused a marked release of attached bacteria (26, 27), providing evidence for the role of proteins in attachment. biofilm is an assemblage of surface-associated microbial cells that is enclosed in an extracellular polymeric substance matrix. Van Leeuwenhoek, using his simple microscopes, first observed microorganisms on tooth surfaces and can be credited with the discovery of microbial biofilms.
