Resistance to aminoglycosides: Glycomics and the link to the human gut microbiome

Research output: Chapter in Book/Report/Conference proceedingChapterpeer-review


The emergence of bacterial resistance to different antibiotics in clinical use, together with the knowledge on the mechanisms by which bacteria resist the action of aminoglycosides, have contributed to the renewed interest in these molecules as potential antimicrobials. Here, we give an overview on natural and semisynthetic aminoglycosides and their structural features and modes of action, focusing on the structural insight underlying resistance mechanisms. Developments on carbohydrate chemistry and microarray technology are highlighted as powerful approaches toward generation of new aminoglycosides and for screening their interactions with RNAs and proteins. The link between antibiotic uptake and the human gut microbiome is also addressed, focusing on gut microbiome function and composition, antibiotic-induced alterations in host health, and antibiotic resistance. In addition, strategies to modulate human microbiome responses to antibiotics are discussed as novel approaches for aminoglycoside usage and for the effectiveness of antibiotic therapy.
