Biofilm sloughing
WebBiofilm formation begins with the adherence of bacteria to a tooth surf ace, followed by a lag phase in which changes in genetic expression (phenotypic shifts)occur. A period of rapid growth then occurs, and an exopolysaccharide matrix is produced. During the steady state, the biofilm reaches growth equilibrium. Surface detachment and sloughing WebBiofilms are also present in the majority of chronic wounds, contributing to delayed wound healing 10,11. Percival and Suleman postulate that there is a direct link between slough and the formation of biofilms on the wound bed 1. Slough as a barrier to wound healing. The appropriate and safe removal of slough is a vital component of wound ...
