Streptomycin sulfate is an aminoglycoside antibiotic drug. Streptomycin Sulfate has a strong antibacterial effect against Mycobacterium tuberculosis. It has a weak antibacterial effect against most Gram-positive cocci (such as various streptococci) and Bacillus (such as Pseudomonas aeruginosa and anaerobic bacteria). Negative bacilli have a strong antibacterial effect. This product is effective against all kinds of cutaneous tuberculosis and has the effect of inhibiting the reproduction and toxin production of Mycobacterium tuberculosis. At high concentrations (>0.4 μg/mL), it has a bactericidal effect. Mycobacterium tuberculosis resistance to streptomycin produced rapidly and should be combined with other anti-tuberculosis drugs.
