ADHESION AND SURFACE GROWTH OF STAPHYLOCOCCUS AUREUS AND LACTOBACILLUS PLANTARUM ON VARIOUS METALS

TL;DRAbstract

Background: One of the major drawbacks in the use of biomedical materials is the occurrence of biomaterial-centered infections. Adhesion of microorganisms to an implant is mediated by their physico-chemical surface properties and the properties of the biomaterial surface itself. Subsequent surface growth of the microorganisms will lead to a mature biofilm and infection, which is difficult to eradicate by antibiotics. Objective: The purpose of this research is to examine the adhesion in the combined cultivation of Staphylococcus aureus and the Lactobacillus plantarum probiotic bacterium on the surface of different metals (copper, aluminium, low-carbon steel, and zinc). Methods: The precise weighing (with an allowance of 0,0001 g) of the metal plates before and after the treatment found a minimum negative change in their weight, which may be caused by reduction resulting from corrosion processes, on one hand, or growth because of the forming of a biofilm, on the other. The structure of t
