Murocin is a topical antibacterial agent, active against those organisms responsible for the majority of skin infections, e.g Staphylococcus aureus, including methicillin-resistant strains, other staphylococci, and streptococci. It is also active against Gram-negative organisms such as Escherichia coli and Haemophilus influenzae. Murocin is used for skin infections, e.g. impetigo, folliculitis, furunculosis.
