Overview
Staphylococcus epidermidis is a Gram-positive, facultative anaerobic coagulase-negative staphylococcus and one of the most abundant commensals of human skin and mucosal surfaces. While generally benign, it is a leading cause of nosocomial infections associated with indwelling medical devices due to its prolific biofilm-forming capacity.
Metal Dependencies and Biofilm
S. epidermidis biofilms exhibit notable metal resistance properties. Metal-based antimicrobial strategies targeting biofilm-embedded staphylococci — including methicillin-resistant strains (MRSE) — leverage the organism's metal dependencies as vulnerabilities ([1]). Essential oils and carvacrol-based codrugs have shown antibiofilm activity against S. epidermidis, disrupting the polysaccharide matrix that shields sessile cells ([2]).
Reproductive Tract Associations
Beyond skin, S. epidermidis is a component of the genital and intestinal microbiota. It has been identified in the reproductive tract microbiome of women with adenomyosis and associated infertility ([3]), suggesting a role in reproductive tract dysbiosis.
