Proteins that promote attachment to collagen, contributing to infections like osteomyelitis and septic arthritis.

Mechanisms used by S. aureus to prevent white blood cells (phagocytes) from engulfing and destroying it.

Substances produced by S. aureus that promote the spreading of infection by helping bacteria breach host tissues and spread.

The direct harm Staphylococcus aureus inflicts on host cells due to the presence of its cell wall component (peptidoglycan).

Toxic substances secreted by S. aureus causing various illnesses such as toxic shock syndrome, food poisoning, and scalded skin syndrome.

Infections affecting the skin and the tissues directly below.

Infections spreading through the bloodstream and affecting internal organs such as blood stream infections, endocarditis, bone/joint infections, and deep abscesses.

A type of food poisoning caused by consuming foods containing toxins produced by S. aureus.
