Additionally, Staphylococcus aureus is a leading cause of pneumonia, particularly in hospitalized patients, and can infect surgical wounds, resulting in deep-seated purulent collections. The organism produces catalase, an enzyme that breaks down hydrogen peroxide, distinguishing it from streptococci.

Systemic and Invasive Diseases In more serious scenarios, the bacterium enters the bloodstream, leading to bacteremia. Biological Characteristics and Identification The structural and biochemical profile of Staphylococcus aureus defines its behavior in both environmental and host settings.
Methicillin-resistant Staphylococcus aureus (MRSA) represents a major global health threat, rendering standard beta-lactam antibiotics ineffective. Its classification as gram positive indicates a thick peptidoglycan layer within the cell wall, which retains the crystal violet stain during laboratory processing.

The arrangement facilitates the organism's resilience and interaction with host defenses compared to more linear bacterial forms. Formation of biofilms on medical devices, increasing resistance to eradication.
