Does bacitracin treat MRSA infections?

MRSA (methicillin-resistant Staphylococcus aureus) infection is a life-threatening bacterial infection caused by Staphylococcus aureus that is resistant to the antibiotic methicillin. Severe cases usually require hospitalization for treatment. MRSA infections are usually treated with systemic antibiotics, either orally or intravenously. Topical bacitracin in combination with neomycin and polymyxin B might be added to the therapy.
