Answer 1

S. epidermidis, a member of the coagulase-negative Staphylococci, is an important commensal organism of the human skin and mucous membranes, and there is growing evidence of its benefit to human health in combating harmful microorganisms.

Staphylococcus epidermidis, a coagulase-negative, and Gram-positive Staphylococcus, is one of five important bacteria found on human skin and mucosal surfaces capable of causing nosocomial infections as a result of the widespread use of medical implants and equipment prior to 1980. The development of colonies on selective media, bacterial morphology by light microscopy, catalase, and slide coagulase testing are all standard methods for detecting S. epidermidis.
