Cayman Streptomycin (sulfate)

Streptomycin is an aminoglycoside antibiotic that inhibits growth of both Gram-negative (MICs = 1 and 16 μg/mL for K. pneumoniae and S. marcescens, respectively) and Gram-positive bacteria (MIC = 0.25 μg/mL for S. pneumoniae).¹ It inhibits growth of M. tuberculosis H37Rv (MIC = 5 μg/mL) and of susceptible strains from clinical isolates (MICs = ≤0.125-1 μg/mL).^2,3 Streptomycin (150 mg/kg), in combination with isoniazid (Item No. 20378), rifapentine (Item No. 20307), and moxifloxacin (Item No. 14830), administered once per week over 6 months to M. tuberculosis-inoculated mice results in clearance of the pathogen from the lungs of the majority of treated mice.⁴ However, after 3 months without treatment, 58% of treated mice produce a positive lung culture. Streptomycin acts by inhibiting protein synthesis in prokaryotes by binding to the 30S ribosomal subunit.^5,6,7,8 It has been used, in combination with penicillin g (Item No. 21615), in antibiotic cocktails to prevent bacterial growth in cell culture.⁹ Formulations containing streptomycin in combination with other antibiotics have been used to treat tuberculosis.
