Used primarily in veterinary medicine, especially in livestock and aquaculture, to treat bacterial infections caused by susceptible pathogens. It is effective against a range of Gram-positive bacteria and some Gram-negative bacteria, making it valuable in controlling respiratory, enteric, and systemic infections in animals. Commonly administered through feed or water, it helps in managing diseases such as swine dysentery, bovine respiratory disease, and certain fish infections. Due to concerns about antibiotic resistance and residue in food products, its use is regulated in many countries, and withdrawal periods are enforced before animal products can enter the food chain.
