Genetics of antibiotic resistance in methicillin-resistant Staphylococcus aureus (MRSA).

Methicillin-resistant Staphylococcus aureus (MRSA) strains pose a significant threat as common causes of bacterial infections in hospitals, often resistant to available antibiotics such as daptomycin, vancomycin, and linezolid. The continuous emergence of new MRSA isolates with no effective treatment options underscores a real threat to health among humans and animals, and the number of effective antibiotic therapies decreases with each passing year. In this review, we provide an overview of the most common genetic mechanisms of resistance to a broad spectrum of antibiotics in methicillin-resistant S. aureus.
