Mechanisms of action of aminoglycoside antibiotics in eucaryotic protein synthesis.
Tetrahymena thermophila is a eucaryotic organism that is highly susceptible to growth inhibition by aminoglycoside antibiotics. Concentrations of paromomycin, gentamicin G418, and hygromycin B at 22, 10, and 17 microM, respectively, inhibited growth by 50%. A combination of in vitro and in vivo methods was used to determine the mechanisms of action of these aminoglycoside antibiotics on protein...
متن کاملAntibiotics: mode of action and mechanisms of resistance.
Antibiotic therapy has revolutionised medical care and has many benefits for patients with or at risk of infections. However, the development of antibiotic resistance now limits the effectiveness of these agents, which is a serious public health concern. This article examines these issues and offers guidance on prescribing strategies and resources for nurse prescribers.
متن کاملMultiple resistance to aminoglycoside antibiotics in actinomycetes.
Actinomycetes were characterized in terms of resistance to 11 different aminoglycoside antibiotics (AGs). Strains freshly isolated in AG containing media showed wide varieties of multiple AG resistance, while the majority of ISP (International Streptomyces Project) cultures and the actinomycete strains isolated in an AG free medium were susceptible to all or most of the AGs tested. Marked chara...
متن کاملOvercoming Aminoglycoside Enzymatic Resistance: Design of Novel Antibiotics and Inhibitors.
Resistance to aminoglycoside antibiotics has had a profound impact on clinical practice. Despite their powerful bactericidal activity, aminoglycosides were one of the first groups of antibiotics to meet the challenge of resistance. The most prevalent source of clinically relevant resistance against these therapeutics is conferred by the enzymatic modification of the antibiotic. Therefore, a dee...
متن کاملBasis for prokaryotic specificity of action of aminoglycoside antibiotics.
The aminoglycosides, a group of structurally related antibiotics, bind to rRNA in the small subunit of the prokaryotic ribosome. Most aminoglycosides are inactive or weakly active against eukaryotic ribosomes. A major difference in the binding site for these antibiotics between prokaryotic and eukaryotic ribosomes is the identity of the nucleotide at position 1408 (Escherichia coli numbering), ...
