WebThe C2DA inhibit methicillin resistant staphylococcus biofilm, but don't eliminate it. The mechanism of the biofilm inhibition by these molecules is still unknown. C2D is a medium of fatty acid chain that effect on staphylococcus aureus biofilm and dispersion of these biofilm. Pseudomonas aeruginosa is the main source for these molecules. Horizontal gene transfer is the lateral transfer of genetic material between cellular organisms. It happens frequently in prokaryotes, and less frequently in eukaryotes. In bacteria, horizontal gene transfer can occur through transformation (uptake of free floating DNA in the environment), transduction (virus mediated DNA uptake), or conjugation (transfer of DNA between pili structures of two adjacent bacteria). Recent studies have also uncovered other mechanisms, such as me… WebThe development of multi-species biofilms in chronic wounds is a serious health problem that primarily generates strong resistance mechanisms to antimicrobial therapy. The use of silver nanoparticles (AgNPs) as a broad-spectrum antimicrobial agent has been studied previously.
