  • General information

    • the following information is not yet verified
      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
      They have a relatively low virulence and can cause infections in patients with lowered resistance, especially in immune compromised patients.

      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.

      Gram positive cocci,

      0.5-1.5 µm

      that occur in irregular grape-like clusters and,
