Name a common pathogen associated with surgical site infections.

Staphylococcus aureus is widely recognized as a common pathogen associated with surgical site infections. It is part of the normal flora of the skin and mucous membranes, which means that it can be introduced into surgical sites during procedures, particularly if proper sterile techniques are not followed. This bacterium is known for its virulence and ability to form biofilms, which can complicate infections and make treatment more challenging.

In surgical contexts, Staphylococcus aureus can lead to serious complications such as abscess formation, wound dehiscence, and even systemic infections if the bacteria enter the bloodstream. Methicillin-resistant Staphylococcus aureus (MRSA), a strain resistant to many common antibiotics, poses an additional risk in healthcare settings. Because of these factors, Staphylococcus aureus is often a focus in infection control protocols and is included in guidelines for prophylactic antibiotic use during surgery to minimize the risk of post-operative infections.
