How does bacitracin heal MRSA?

Bacitracin is primarily effective against certain Gram-positive bacteria, including some strains of Staphylococcus aureus, but it is generally not used to treat Methicillin-Resistant Staphylococcus aureus (MRSA) infections due to its limited spectrum of activity. Instead, MRSA typically requires treatment with antibiotics such as vancomycin or linezolid. Bacitracin may be used topically for minor skin infections or in combination with other agents, but it is not a frontline treatment for systemic MRSA infections. Its role in MRSA healing is thus minimal and more supportive than curative.
