bacitracin [bas″ĭ-tra´sin] an antibacterial polypeptide elaborated by the licheniformis group of Bacillus subtilis; it is effective against a wide range of gram-positive and a few gram-negative bacteria; also used as the zinc salt. It is applied topically to the skin and eye.bac·i·tra·cin (bas'i-trā'sin), An antibacterial antibiotic polypeptide of known chemical structure isolated from cultures of an aerobic, gram-positive, spore-bearing bacillus (member of the Bacillus subtilis group); active against hemolytic streptococci, staphylococci, and several types of gram-positive, aerobic, rod-shaped organisms; usually applied locally. Zinc bacitracin is also available. [Bacillus + Margaret Tracy, source of orig. culture] bacitracin (băs′ĭ-trā′sĭn)n.

[Bacillus + Margaret Tracy, source of orig. culture]bacitracin An antibiotic derived from the bacterium Bacillus subtili s. It acts by interfering with the formation of the bacterial cell membrane and is highly effective against many organisms especially the HAEMOLYTIC streptococcus. Unfortunately, it is so liable to damage the kidneys that it must be confined to external use. Brand names of prparations containing bacitracin are Cicatrin and Polyfax.bacitracin An antibiotic drug with similar properties to penicillin and effective principally against gram-positive bacteria, such as Staphylococci and Streptococci. It is mainly used in combination with other agents (e.g. polymyxin B) for treating external eye infections (e.g. blepharoconjunctivitis).bac·i·tra·cin (bas'i-trā'sin) Antibacterial antibiotic polypeptide isolated from cultures of an aerobic, gram-positive, spore-bearing bacillus; active against hemolytic streptococci, staphylococci, and several types of gram-positive, aerobic, rod-shaped organisms; usually applied locally. bacitracin
