Kitasamycin is widely used in veterinary medicine as an antibiotic to treat infections caused by Gram-positive bacteria and some Gram-negative bacteria. It is particularly effective in controlling respiratory tract infections, gastrointestinal infections, skin infections, mastitis, and other bacterial diseases in livestock such as pigs, cattle, buffalo, and poultry. In aquaculture, it is applied to prevent and treat bacterial infections in fish and shellfish, ensuring healthier stock and improved yield. Additionally, kitasamycin is sometimes incorporated into animal feed as a growth promoter, enhancing feed efficiency and overall animal growth. Its broad-spectrum activity and relatively low toxicity make it a valuable tool in managing bacterial infections in animals and supporting agricultural productivity. However, it should be used with caution to prevent the development of antibiotic resistance.
