Abstract: The rise of antimicrobial resistance in Staphylococcus aureus poses a significant threat to public health, with methicillin-resistant S. aureus (MRSA) being one of the most notorious strains. The mechanisms driving resistance in S. aureus are diverse, including the acquisition of resistance genes, overexpression of efflux pumps like NorA and MepA, and adaptations such as cell wall thickening. This review highlights key resistance mechanisms, focusing on MRSA and vancomycin-resistant S. aureus (VRSA), as well as efflux pumps that contribute to multidrug resistance. Additionally, we explore the role of biofilm formation in protecting bacterial cells from antibiotic action, particularly in chronic and device-related infections. Understanding these resistance pathways is essential for the development of alternative therapeutic strategies, including efflux pump inhibitors and anti-biofilm agents. The increasing complexity of treating S. aureus infections underlines the importance of continued research and the implementation of stringent infection control measures to limit the spread of resistant strains.
