Streptomycin

From Simple English Wikipedia, the free encyclopedia
Space-filling model of streptomycin

Streptomycin is an aminoglycoside antibiotic, and was the first of these to be discovered in 1943 by Albert Shatz.[1][2][3] The use of streptomycin involves the disruption of protein synthesis within the ribosome, preventing replication of bacteria.[4] It arises from the bacteria Streptomyces griseus and is majorly used in the treatment of infections from aerobic gram-negative bacteria.[1]

Molecular Structure of Streptomycin

Streptomycin has been classified by the World Health Organisation as a critically important antimicrobial for human medicine.[5] The most common use of streptomycin today is the treatment of pulmonary tuberculosis.[1] The antibiotic has a variety of antibacterial activity which is beneficial for the treatment of a wide range of infections.[6] Other infections treated using streptomycin include pneumonia, Mycobacterium avium complex-MAC, E. coli influenza, plague, and tularemia.

Side effects

[change | change source]

Common side effects of the use of streptomycin coincide with those seen with the use of other aminoglycoside antibiotics. These include both kidney and ear toxicity, alongside chronic kidney disease.[7] Other dangerous side effects of the use of this drug also include vestibular and auditory system disorders.[8]

Mechanism of action

[change | change source]

The use of streptomycin involves the disruption of protein synthesis within the ribosome, preventing the replication of bacteria.[4] The antibiotic creates ionic bonds with the negatively charged sections of the bacterial cell membrane to access the inner cytoplasmic membrane.[9] Streptomycin is only effective against aerobic bacteria as an electron transport system used within the respiratory cycle is needed,[1] however, the antibiotic is able to inhibit both gram-positive and gram-negative bacteria.[10]
