What is another word for tyrocidine?
Pronunciation: [tˈa͡ɪɹəsˌɪdiːn] (IPA) 
Tyrocidine is a cyclic decapeptide antibiotic produced by the bacteria Bacillus brevis. There are several other names that can be used synonymously with tyrocidine, including bacitracin, colistin, and polymyxin B. These antibiotics all have similar mechanisms of action, which involve disrupting the bacterial cell membrane. Tyrocidine was one of the first antibiotics discovered and its use has largely been supplanted by newer antibiotics with fewer side effects. However, it continues to be used topically in some cases, particularly for treating skin infections caused by Gram-positive bacteria. As with any antibiotic, it is important to use tyrocidine only as directed by a healthcare professional to avoid the development of antibiotic-resistant strains of bacteria.
