Adhesive properties to materials used in unit care by Staphylococcus aureus strains incubated in seawater microcosms

Four strains of Staphylococcus aureus were incubated for eight months in seawater microcosms and then tested for their ability to form a biofilm on different surfaces. Our results showed that the stressed strain became safranin and increased their capacity for producing biofilm on polystyrene microplates or glass wells. These bacteria were able to form a biofilm on the surfaces tested and the cell density was the highest on the stainless steel surface followed by polystyrene and the polyethylene surfaces. These properties allow these bacteria to survive, proliferate and persist even after treatment with antibacterial agents.
