Biofilm glycocalyx
WebBiofilm is a complex aggregation of microorganisms. Biofilm, also called glycocalyx, functions within an extracellular slimy exopolysaccharide material. The morphology and pathogenesis of biofilm as it relates to Staphylococcus epidermidis in orthopaedic implant patients are presented. WebA biofilm comprises any syntrophic consortium 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 (EPSs). The cells within the biofilm produce the EPS components, which are typically a …
