| [investigation of biofilm formation properties of staphylococcus isolates]. | biofilm production is an important virulence factor which allows staphylococci to adhere to medical devices. the principal component of biofilm is a "polysaccharide intercellular adhesin (pia)" which is composed of a beta-1,6-n-acetylglucosamine polymer synthesized by an enzyme (n-acetylglucosamine transferase) encoded by the ica operon found on the bacterial chromosome. this operon is composed of four genes (a, b, c, and d), and a transposable element is256. in this study, we aimed to determine ... | 2017 | 28283006 |
