General information
- Taxonomy
  Family: Staphylococcaceae
  
  Natural habitats
  Isolated from the human and animal skin.
  
  Clinical significance
  S. sciuri and S. xylosus are commensals of the skin and the mucous membranes of many animalsand, occasionally of humans.
  
  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
- Gram positive cocci
  
  ,0.7-1.2 µm
  
  that occur in irregular grape-like clusters and,
  
  less often, single and in pairs, tetrads, and in short chains.
Culture characteristics
- Facultative anaerobic
  
  BA: medium to large, raised, smooth, glistening, circular, opaque, most strains pigmented yellow in center of colonies.
