Abstract: Aminoglycosides are a group of antibiotics often used to treat serious infections, especially those caused by multidrug resistant bacteria like MRSA (methicillin-resistant Staphylococcus aureus). These antibiotics have been important in medicine since their discovery in the 1940s. They work by stopping bacteria from synthesizing proteins properly, killing them. This happens because aminoglycosides attach to the bacterial ribosome (the 30S subunit), disrupting protein production. However, they need to be used carefully because of their nephrotoxicity and ototoxicity. In recent years, bacteria have become more resistant to aminoglycosides. The mechanism of action involved in the aminoglycoside resistance can happen in different ways, such as bacteria changing the drug with special enzymes, altering their ribosomes, using efflux-pumps, or making their membranes harder for the drug to get through. MRSA bacteria often carry resistance genes in their chromosomes or plasmids, making treatment harder. Because of this, it's important to increase the effort to develop new aminoglycosides that can bypass these resistance strategies, in addition to researching the way how the aminoglycoside resistance genes spread worldwide.
