Formation of biofilm by Staphylococcus xylosus

Abstract

The ability of 12 Staphylococcus xylosus strains to form biofilm was determined through the study of different criteria. Eleven out of the 12 strains were able to form biofilm, 10 preferentially on hydrophilic support (glass) and one, S. xylosus C2a, on both hydrophilic and hydrophobic (polystyrene) supports. The determination of bacterial surface properties showed that all strains were negatively charged with five strains moderately hydrophobic and seven hydrophilic. The bap and icaA genes, important for biofilm formation of some staphylococci, were searched. All strains were bap positive but icaA negative. Furthermore, S. xylosus strain C2a was studied on two supports widely used in the food industry, polytetrafluoroethylene (PTFE, hydrophobic) and stainless steel (hydrophilic) and appeared to adhere preferentially on stainless steel. Addition of 20 g/l of NaCl to Tryptic Soy Broth medium (TSB) did not improve significantly its adhesion but enhanced both bacterial growth and cell survival, which were optimum in this medium. Environmental scanning electron microscopy showed that S. xylosus C2a colonized the surface of stainless steel chips with intercellular spaces. The strain formed cell aggregates embedded in an amorphous po...Continue Reading

Adhesion Molecules in Health and Disease

Cell adhesion molecules are a subset of cell adhesion proteins located on the cell surface involved in binding with other cells or with the extracellular matrix in the process called cell adhesion. In essence, cell adhesion molecules help cells stick to each other and to their surroundings. Cell adhesion is a crucial component in maintaining tissue structure and function.
