bacitracin acitracin n. (1940) [Bacillus + Margaret Tracy, (a child whose tissues contained {Bacillus subtilis}) + -in. --RHUD.] a polypeptide antibacterial antibiotic of known chemical structure effective against several types of Gram-positive organisms, and usually used topically for superficial local infection.

Note: It is produced by {Bacillus subtilis} and {Bacillus licheniformis}, and as produced commercially is composed of several closely related substances. The predominant component, {Bacitracin A}, has a formula {C60H103N17O16S}, and contains D-ornithine, D-phenylalanine and D-glutamine residues as well as the L-isomers of leucine, isoleucine, histidine, asparagine and aspartic acid. --[MI11] [WordNet 1.5]
