    Abstract: A process is disclosed for culturing clinical Staphylococcus epidermidis cells that reproducibly enables identification of a limited number of predominant serotypes. Two predominant serotypes common to most clinical cases of S. epidermidis have been identified and are denoted Type I and Type II. A particular polysaccharide surface antigen is associated with each of the Type I and Type II serotypes. The surface antigens can be used to provide active and passive immunization against S. epidermidis infection and to produce a hyperimmune immunoglobulin or antibodies for treatment of S. epidermidis infection.
