Biofilm microorganisms
Web4. Biofilms make bacteria less susceptible to antimicrobial agents. Many studies have shown that the multicellular construction of biofilms affords protection for cells. This protection is the result of intrinsic shifts in genetic expression when floating bacterial cells attach to surfaces and begin to form biofilms. WebBiofilm formation is a natural phenomenon which occurs wherever there are microorganisms and surfaces – whether only slightly wet or immersed, and whether …

WebA biofilm is an architectural colony of microorganisms, within a matrix of extracellular polymeric substance that they produce. Biofilm contains microbial cells adherent to one-another and to a static surface (living or non-living). Bacterial biofilms are usually pathogenic in nature and can cause nosocomial infections. WebMicrobial biofilms develop when microorganisms irre-versibly adhere to a submerged surface and produce extracellular polymers that facilitate adhesion and provide a structural matrix. This surface may be inert, nonliving material or living tissue. Biofilm-associated microorganisms behave differently from planktonic (freely suspended)
