Abstract
Staphylococcus epidermidis is an important opportunistic human pathogen that has recently emerged as a major cause of foreign-body infections. The most important stage contributing to the pathogenesis of this bacteria is the initial adherence to host tissue. SdrG is a cell-wall–anchored fibrinogen-binding adhesin of S. epidermidis that has been shown to be necessary for bacterial binding to fibrinogen-coated foreign bodies, such as catheters. Here we report the generation and characterization of a panel of monoclonal antibodies (MAbs) directed against this S. epidermidis virulence factor. Through the use of multiple in vitro assays, surface plasmon resonance, and flow cytometry, we have characterized a diverse array of MAbs that may prove to be beneficial in studies that address the precise biologic role of SdrG.
