Synergism between metallic nanoparticles and antibiotics

Appl Microbiol Biotechnol. 2022 Jun 7. doi: 10.1007/s00253-022-12001-1. Online ahead of print.ABSTRACTThe discovery of antibiotics in the twentieth century made it possible to treat bacterial infections and revolutionized modern medicine. However, gradually, it is possible to perceive a decrease in the effectiveness of antimicrobial agents against pathogenic isolates, which, together with the low investment in the discovery and/or development of new antibiotics by large pharmaceutical companies since the 1960s, makes it increasingly difficult to treatment of infections caused by these microorganisms. The search for strategies capable of potentiating the effect of existing drugs through the development of new therapeutic approaches, which also have the potential to circumvent bacterial resistance to antibiotics, has become indispensable. In this context, metallic nanoparticles stand out, as they could be used to act synergistically with drugs. Thus, the objective of this review was to present the latest information on the synergistic activity of antibiotics with metallic nanoparticles, pointing out this association as a promising alternative for the preservation of bacterial sensitivity to these drugs. The different metallic nanoparticles can present different benefits in the treatment of bacterial infections, with this being able to potentiate the bacterial activity of antibiotics that are widely used in the clinic, being able to increase the susceptibility in multiresistant ...
