Description and significance
Staphylococcus epidermidis is a gram positive coccus, a normal inhabitant of the human skin that grows in clusters. It is an aerobic organism but is yet capable of growing anaerobically when placed in a standardized, complex medium of glucose. Experimental research reveals that S. epidermidis lives in close association with S. aureus, a very destructive pathogen.
Even though a coagulase-negative gram bacterium, S. epidermidis has been lately classified among the most important pathogens responsible for divers nosocomial infections. Most strains are highly resistant to multiple antibiotics, such as penicillin, tetracycline, methicillin and many more, which makes it very difficult to treat the infections resulting from these bacteria. According to the Centers for Disease Control and Prevention's National Nosocomial infection surveillance system, S. epidermidis is responsible for 33.5% of nosocomial blood stream infections.
