Study Notes
Staphylococcal Infections
- The presence of a capsule in staphylococci interferes with opsonization and subsequent phagocytosis.
- The production of coagulase is an important indicator of pathogenicity in staphylococci.
- The binding of bacterial surface components to fibronectin and fibrinogen facilitates bacterial attachment to tissues damaged by toxic factors.
- The virulence factor of S.aureus, enterotoxin, is plasmid or phage-mediated.
- The presence of damaged tissues, for example, those caused by toxic factors, may predispose to the development of staphylococcal infection.
- The production of the polysaccharide capsule interferes with opsonization and subsequent phagocytosis.
- Coagulase is a marker for pathogenicity and is an important indicator of pathogenicity in staphylococci.
- The binding of bacterial surface components to fibronectin and fibrinogen facilitates bacterial attachment to damaged tissues.
- Most of the virulence factors in staphylococci are encoded in the genome as chromosomal genes.
- The surface component of staphylococci that binds to fibronectin and fibrinogen is the polysaccharide capsule.
