Which antibiotics are commonly used to treat MRSA infections?

• A. Penicillin and amoxicillin
• B. Ciprofloxacin and levofloxacin
• C. Vancomycin and Bactrim
• D. Erythromycin and tetracycline

Answer: (C)

The treatment of MRSA (Methicillin-Resistant Staphylococcus Aureus) infections typically involves antibiotics that are specifically effective against this resistant strain of bacteria. Vancomycin is one of the primary antibiotics used for serious MRSA infections, as it has a strong efficacy against gram-positive bacteria, including those resistant to methicillin. Additionally, Bactrim (trimethoprim-sulfamethoxazole) is another antibiotic that can be used for treating certain MRSA infections, particularly less severe cases or skin and soft tissue infections. The combination of these two antibiotics provides a reliable therapeutic option, reinforcing the rationale for their use in treating MRSA. Their effectiveness is due to differing mechanisms of action and their ability to target resistant strains that would not respond to more common antibiotics. The other options do not contain effective agents for treating MRSA. For instance, penicillin and amoxicillin are ineffective against MRSA because the bacteria have evolved to produce beta-lactamase enzymes that can deactivate these antibiotics. Ciprofloxacin and levofloxacin are fluoroquinolones, which may have some activity against certain strains of Staphylococcus, but they are generally not the first choice for MRSA and often have resistance issues.
