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. 2D line-angle representation.. Aminoglycoside is a medicinal and bacteriologic category of traditional Gram-negative antibacterial medications that inhibit protein synthesis and contain as a portion of the molecule an amino-modified glycoside ().
Tetracyclines inhibit protein synthesis in both bacterial and human cells. Bacteria have a system that allows tetracyclines to be transported into the cell, whereas human cells do not. Human cells therefore are spared the effects of tetracycline on protein synthesis. [1]
While the MIC is the lowest concentration of an antibacterial or antifungal agent necessary to inhibit visible growth, the minimum bactericidal concentration (MBC) is the minimum concentration of an antibacterial agent that results in bacterial death. It is defined by the inability to re-culture bacteria, and the closer the MIC is to the MBC ...
Streptomyces is the largest genus of Actinomycetota, and the type genus of the family Streptomycetaceae. [3] Over 700 species of Streptomyces bacteria have been described. [4] [5] [6] As with the other Actinomycetota, streptomycetes are gram-positive, and have very large genomes with high GC content.
Pen-Strep (also known as penicillin-streptomycin) is a mixture of penicillin G and streptomycin that is widely used in mammalian cell culture media to prevent bacterial contamination. The solution contains 5,000 units of penicillin G (sodium salt) which acts as the active base, and 5,000 micrograms of streptomycin (sulfate) (base per milliliter ...

Narrow-spectrum antibiotics have low propensity to induce bacterial resistance and are less likely to disrupt the microbiome (normal microflora). [3] On the other hand, indiscriminate use of broad-spectrum antibiotics may not only induce the development of bacterial resistance and promote the emergency of multidrug-resistant organisms, but also cause off-target effects due to dysbiosis.
