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 (sanchez rosario 2026 bmdc metal antimicrobial mrsa biofilm). Essential oils and carvacrol-based codrugs have shown antibiofilm activity against S. epidermidis, disrupting the polysaccharide matrix that shields sessile cells (cacciatore 2015 carvacrol codrugs antimicrobial antibiofilm).
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 (ponomaryova 2022 adenomyosis infertility genital intestinal microbiota), suggesting a role in reproductive tract dysbiosis.
