Taxonomy
Family: Staphylococcaceae

Natural habitats
They are ubiquitous in nature, and is part of the normal flora of the skin and less commonly the mucosa flora.

Clinical significance
S. epidermidis is an opportunistic pathogen, primarily causing infections in immunocompromised patients or those with implanted medical devices.

It can lead to infections such as catheter-associated bloodstream infections, prosthetic joint infections, urinary tract infections and endocarditis.

Its ability to form biofilms on medical devices makes it particularly difficult to treat, often requiring prolonged or combination antibiotic therapy.

CNS infections occur in implantation of foreign objects, such as intravenous catheters or bone prostheses.

Is repeatedly CNS, in pure culture or in mixed culture isolated from the material, then this confirms the presence of an infection.

The correct identification of CNS is necessary in order to get an idea of the pathogens in this group.
