Colistin sulfate is a polymyxin antibiotic used in veterinary medicine to treat gram-negative bacterial infections, especially in livestock like poultry and swine. It works by disrupting bacterial cell membranes, making it effective against E. coli, Salmonella, and Pseudomonas. Typically administered orally, it helps control intestinal infections but requires careful use to prevent resistance.
