الإجابة: A. Staph aures
Infections of intravascular catheters and other devices are caused by skin staphylococci. The sources name S. epidermidis (spread through infected IV catheters) and S. aureus (acute infections involving prosthetic material and pacemakers/ICDs). Of the options given, Staph aureus is the only staphylococcus.
- Group A and group B streptococci are not typical line pathogens.
- Enterococcus is linked mainly to nosocomial UTIs and GI/GU procedures.

S. aureus is the most common cause of acute endocarditis in people who inject drugs and in patients with prosthetic valves or pacemakers/ICDs, so it is the device-related organism among these options. The other staphylococcus in the notes, S. epidermidis, causes bacteremia from infected venous catheters.

Group B streptococci are named as a cause of bacterial meningitis in neonates (with E. coli and Listeria). On the same page it is S. aureus and other staphylococci that are linked to indwelling devices.

Enterococcus is tied to endocarditis after nosocomial UTIs and after GI or GU procedures, so it belongs to those sources rather than to a central-line infection.
