Protein A
Enhance binding to host cells & prosthetics
Binds to the Fc region of antibody (IgG)
involves the activation of plasma coagulase-reacting factor (CRP), to produce the fibrin clot
Staphylococcus epidermidis is able to cause diseases by its ability to form biofilms by way of cell surface & extracellular compounds.
These cell surface structures and extracellular substances promote adherence of bacteria to surfaces of prosthetic devices.
