bacitracin

/ˌbæsɪˈtreɪsɪn/

noun

An antibiotic typically used topically for skin and eye infections.

If the area of affected skin is limited, mupirocin is an effective topical therapy; it was more effective than the other topical antibiotics studied (i.e., neomycin, bacitracin, polymyxin B, and gentamicin).
