Description

Bacitracin Complex CAS NO 85800-09-5 is a polypeptide antibiotic complex primarily composed of bacitracin A, produced by certain strains of *Bacillus subtilis*. This compound is valued for its potent bactericidal activity against a broad spectrum of Gram-positive organisms, including many resistant strains. It is an essential raw material for manufacturers in the pharmaceutical, veterinary medicine, and animal feed industries, where it is used to formulate topical ointments, medicated powders, and growth-promoting feed additives.

Application

• Pharmaceutical Formulations: Key active ingredient in topical antibiotic ointments, creams, and ophthalmic preparations for human use.
• Veterinary Medicine: Used in wound sprays, udder creams, and other topical treatments for livestock and companion animals.
• Animal Nutrition: Incorporated into feed premixes as a growth promoter and prophylactic agent in poultry, swine, and aquaculture.
• Microbiological Research: Serves as a selective agent in culture media and as a standard in antibiotic susceptibility testing.
• Combination Therapies: Often formulated with other antibiotics like neomycin and polymyxin B for broader-spectrum topical applications.
• Preservative Systems: Utilized in certain cosmetic and personal care products for its antimicrobial properties.
