An aminoglycoside antibiotic
Dihydrostreptomycin is an aminoglycoside antibiotic and a derivative of streptomycin .1 It is active against B. subtilis, K. pneumoniae, S. marcescens, S. aureus, P. aeruginosa, and M. tuberculosis (MICs = 0.07, 0.08, 0.09, 0.06, 0.8, and 5.7 ?g/ml, respectively). It interferes with bacterial protein synthesis by binding the 30S ribosomal subunit.2 Dihydrostreptomycin enhances phagocytosis and intracellular killing of E. coli by isolated mouse peritoneal macrophages.3 It improves survival in a mouse model of S. aureus infection.4 Formulations containing dihydrostreptomycin have been used in the prevention and treatment of bacterial infections in livestock.
