As human and bacteria both have ribosomes, streptomycin has significant side effects in humans. At low concentrations, however, streptomycin inhibits only bacterial growth. [18] Streptomycin is an antibiotic that inhibits both Gram-positive and Gram-negative bacteria, [19] and is therefore a useful broad-spectrum antibiotic.
Streptomycin is noteworthy because it is the first significant antibiotic discovered after penicillin, the first systemic antibiotic discovered in America, the first antibiotic active against tuberculosis, and the first-line treatment for plague.
The US Patent Office granted U.S. patent 2,449,866 titled "Improvement in Streptomycin and Processes of Preparation" to Schatz and Waksman on 21 September 1948. [6] Merck was to get an exclusive right for commercial production. [32] Schatz was the lead author of the paper on streptomycin discovery with Bugie as the second.
Streptomycin is the first-in-class aminoglycoside antibiotic. It is derived from Streptomyces griseus and is the earliest modern agent used against tuberculosis. Streptomycin lacks the common 2-deoxystreptamine moiety (image right, below) present in most other members of this class.
Streptomyces isolates have yielded the majority of human, animal, and agricultural antibiotics, as well as a number of fundamental chemotherapy medicines.Streptomyces is the largest antibiotic-producing genus of Actinomycetota, producing chemotherapy, antibacterial, antifungal, antiparasitic drugs, and immunosuppressants.

Selman Abraham Waksman (July 22, 1888 – August 16, 1973) was a Jewish American inventor, Nobel Prize laureate, biochemist and microbiologist whose research into the decomposition of organisms that live in soil enabled the discovery of streptomycin and several other antibiotics.
Neomycin was discovered in 1949 by the microbiologist Selman Waksman and his student Hubert Lechevalier at Rutgers University. It is produced naturally by the bacterium Streptomyces fradiae . [ 3 ] Synthesis requires specific nutrient conditions in either stationary or submerged aerobic conditions.
One of the main components is neomycin sulfate, which is a type of antibiotic discovered in 1949 by microbiologist Selman Waksman at Rutgers University. [21] Neomycin belongs to the aminoglycoside class of antibiotics and fights against Gram positive and gram negative bacteria. The antibiotic is often used to prevent risk of bacterial ...
