MVs were isolated from S. aureus and analyzed by mass
spectrometry. Some of those identified proteins include
the IgG-binding protein, ferritin, ferrichrome-binding
lipoprotein precursor, ABC transporter extracellular binding
protein, β-lactamase, and membrane protein oxaA.
Also S. aureus MVs interacted with the plasma membrane
of host cells via a cholesterol-rich membrane microdomain
and delivered the protein A to host cell
