Notably, it is a leading cause of hospital-acquired infections. It notes that S. It contributes through supporting a healthy skin barrier, healing cuts of the skin, protecting the skin microbiota from colonization of skin pathogens, and acting as an immune system modulator. epidermidis is protected against attacks from the immune system and against antibiotic treatment, making S. aureus-type wall teichoic acid—alters the lifestyle of S. While it is generally considered a harmless bacterium, it can cause infections, particularly in healthcare settings. Indwelling medical devices such as intravenous catheters, prosthetic joints, and Key Takeaways Staphylococcus epidermidis is a round, gram-positive, catalase-positive, coagulase-negative, and urease-positive bacteria, which is normally part of the normal human flora, especially on the skin and mucosa.

Oct 10, 2025 · One of the best ways to make sure you get the best antibiotic is by getting a susceptibility test (or an antibiotic sensitivity test). In a biofilm, S. Both staphylococci and streptococci have round, spherical cell shape, but the arrangement of cells is different due to a different binary fission. Many Doctors will prescribe a drug based on their clinical experience, standard protocol or by Keywords: Candida albicans, Staphylococcus aureus, Staphylococcus epidermidis, polymicrobial infections, biofilms, interspecies interactions, interkingdom interactions Introduction Candida albicans is a commensal fungus that colonizes the oral cavity, vagina, and gastro-intestinal tract in most humans (Nobile and Johnson, 2015). Jul 9, 2022 · What is Staphylococcus epidermidis? Staphylococcus epidermidis is a Gram-positive bacterium belonging to the genus Staphylococcus and is the most frequently isolated species from human epithelia.
