Abstract Biofilms are complex surface associated communities where bacterial cells enclosed by self-produced extra cellular polymeric substances (EPS), mainly consisting of exopolysaccharides, proteins and extracellular DNA. Treatment biofilm persistent infections is an emerging issue for clinicians as adhere with human epithelial or indwelling medical devices such implants catheters, used in urinary tract respiratory infections. Several methods practice to assess the formation strains. Most...
