Potential use of solid phase immunoassays in the diagnosis of coagulase-negative staphylococcal infections.
Staphylococcus epidermidis is a major nosocomial pathogen, even though it is a member of the normal bacterial flora of skin and the mucous membranes. A major complication is the development of biofilms on implanted medical devices. Diagnosis of coagulase-negative staphylococcal infections relies on the presence of clinical manifestation of infections and on microbiologic evidence, usually obtained after the removal of the biomaterial. Solid-phase immunoassays have not yet been used for routine diagnosis of coagulase-negative staphylococcal infections and distinction between pathogenic and normal cocci. The enzyme immunoassays developed in the last decade are presented in this review article. Serodiagnosis has been attempted by determining antibodies against bacterial cells, mixtures of S. epidermidis slime antigens and discrete slime antigens. Detection or typing of staphylococcal cells has been performed by specific antibodies and lectins. There is still a long way until the application of such assays in the routine clinical laboratory and large clinical studies are necessary.
