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 effectiveness and reduce the risk of resistance. In veterinary medicine, it is employed to treat infections in livestock, ensuring animal health and food safety. Additionally, it is utilized in agricultural settings to control bacterial diseases in crops, contributing to improved yield and crop quality. Its application extends to research laboratories, where it serves as a selective agent in cell culture to prevent bacterial contamination.
