General information

• the following information is not yet verified
  Taxonomy
  Family: Staphylococcaceae
  
  Natural habitats
  They are ubiquitous in nature, but are mainly found on the skin of human, mammals and birds.
  
  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,
  
  0.5-1.2 µm
  
  that occur in irregular grape-like clusters and,
  
  less often, single and in pairs, tetrads, and in short chains.

Culture characteristics

• the following information is not yet verified
  

  Facultative anaerobic
  
  Colonies are small to medium, smooth, slightly convex, opaque, glistening, white or grayish.
  Some species become yellowish or yellowish-orange, after storage in the cold (4-10°C).
  
  Non or delayed hemolysis and grows best under aerobic conditions.
