Taxonomy
Family: Staphylococcaceae
Natural habitats
Is part of the normal flora of the 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 positive cocci,
0.5-1.2 µm
predominantly in singly, tetrads and pairs
Facultative anaerobic
BA: colonies are medium to large, convex, opaque, smooth, glistening, non pigmented or occasionally have a slightly yellowish tint. Weak hemolysis is detected.
