Originally isolated by Selman A. Waksman and Albert Schatz in 1947, streptomycin is effective against tubercle bacilli and is a mainstay of tuberculosis therapy. Because streptomycin-resistant tubercle bacilli emerge during treatment, the antibiotic is usually used in combination with one or more of the drugs isoniazid isoniazid (ī'sōnī`əzĭd), drug used to treat tuberculosis .

Possible side effects include injury to the kidneys and nerve damage that can result in dizziness and deafness.

streptomycin

Antibiotic synthesized by the actinomycete Streptomyces griseus, found in soil. It was among the first antibiotics discovered (1943, by Selman Waksman), after penicillin, gramicidin, and tyrocidine. The first antibiotic effective against tuberculosis, it interferes with the tubercle bacillus's ability to synthesize certain vital proteins. It still has some use in combination with penicillin for treating endocarditis and with tetracyclines in the treatment of plague, tularemia, and brucellosis.
