General information

• the following information is not yet verified
  Taxonomy
  Family: Staphylococcaceae
  
  Natural habitats
  Isolated from the human and animal skin.
  
  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 stain

• the following information is not yet verified
  Gram positive cocci,
  
  0,5-1.5 µm
  
  that occur in irregular grape-like clusters and
  
  less often, sinle and in pairs, tetrads and short chains
