Abstract

Previous studies have demonstrated that Staphylococcus epidermidis isolates colonizing the skin of healthy humans do not typically encode icaADBC, the genes responsible for the production of polysaccharide intercellular adhesin or biofilms. It was therefore hypothesized that the presence of icaADBC was deleterious to the successful colonization of human skin by S. epidermidis. Using a human skin competition model, it was determined that the strong biofilm-producing S. epidermidis strain 1457 was outcompeted at 1, 3, and 10 days by an isogenic icaADBC mutant (1457 ica::dhfr), suggesting a fitness cost for carriage of icaADBC.
