Staphylococcus epidermidis has a sized at about 0.5-1.5 micrometers in diameter that grows in aerobic conditions. It forms biofilm that consists of clusters of cells embedded in extracellular slime with a thickness of 160 micrometers. It has glycerol teichoic acid glucosyl residues and is capable of growing with glucose anaerobically. The biofilm permits this bacterium to adhere in living areas which then releases host immune response to antigens preventing removal and tissue damage.

Staphylococcus epidermidis linked to nosocomial infections associated with intravascular devices including cerebrospinal fluid shunts, prosthetic heart valves, urinary tract and catheters that lead to severe inflammation and pus secretion.

Staphylococcus epidermidis is implicated in endocarditis and septicemia manifest by painful urination as well as extent fever, headache and fatigue susceptible to newborns, drug users, elderly and those catheter users. It is prone to contaminate environmental surfaces and patient-care equipment.
