General information
- Taxonomy
  Family: Staphylococcaceae
  
  Natural habitats
  They are ubiquitous in nature and is part of the normal skin flora of poultry.
  
  Clinical significance
  S. gallinarum are found on several mammals and food products
  
  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,
  
  0.5-1.5 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: colonies are dull white, dry, large, flat with ragged edges after 12 hours incubation and became light yellow after 20 hours incubation and dark yellow pigmented after 44 hours incubation. Hemolysis weak
