How do fimbriae create biofilm
WebBiofilm formation is a strategy by which microorganisms survive and adapt to the involving environment, particularly adverse conditions. The development of a biofilm includes attachment of cells to a surface, multiplication, maturation, and production of a polymeric matrix, and finally microbial detachment and colonization of new surfaces.
