Zinc Bacitracin

Zinc bacitracin is a potent antibacterial agent effective against a wide range of gram-positive bacteria, including Staphylococcus aureus, Streptococcus, Enterococcus, Clostridium, and Corynebacterium. It also shows efficacy against actinomycetes and spirochetes, with minimal instances of bacterial resistance reported. As a drug feed additive, bacitracin is utilized in various animals to enhance growth, and it is frequently combined with antibiotics that target gram-negative bacteria, such as colistin and neomycin. Clinically, zinc bacitracin is primarily employed to promote growth in livestock and manage bacterial diarrhea, as well as to treat swine dysentery caused by Treponema. Its role in veterinary medicine underscores its importance in improving animal health and productivity.
