Streptomycin sulfate is widely used in the treatment of bacterial infections, particularly those caused by gram-negative bacteria. It is a key antibiotic in combating tuberculosis, often administered in combination with other drugs to enhance its efficacy and reduce the risk of resistance. In veterinary medicine, it is employed to treat infections in livestock and poultry, ensuring animal health and productivity. Additionally, it is utilized in agricultural settings to control bacterial diseases in crops, helping to improve yield and quality. Streptomycin sulfate also plays a role in research laboratories, where it is used as a selective agent in cell culture to prevent bacterial contamination. Its broad-spectrum antibacterial properties make it a valuable tool in both medical and agricultural applications.
