Reducing bacterial antibiotic resistance by targeting bacterial metabolic pathways and disrupting RND efflux pump activity
ABSTRACT Antibiotic resistance is a significant issue for the medical community, worldwide. Many bacteria develop drug resistance by utilizing multidrug resistant or MDR efflux pumps that can export antibiotics from bacterial cells. Antibiotics are expelled from bacteria by efflux pumps a part of the resistance nodulation division (RND) family. Types of RND efflux pumps include the AcrAB-TolC tripartite protein pump. There are an excessive number of antibiotic compounds that have been discovered; however, only a few antibiotics are effective against MDR bacteria. Many bacteria become drug resistant when sharing genes that encode MDR efflux pump expression. MDR efflux pump encoding genes are incorporated into plasmids and then shared among bacteria. As a consequence, advancements in genetic engineering can sufficiently target and edit pathogenic bacterial genomes for perturbing drug resistance mechanisms. In this perspective and review, support will be provided for utilizing genetic modifications as an antimicrobial approach and tool that may effectively combat bacterial MDR. Ayhan et al. found that deleting acrB, acrA, and tolC increased the levels of antibiotic sensitivity in Escherichia coli. Researchers also found that glucose, glutamate, and fructose all induced the absorption of antibiotics by upregulating the gene expression of maeA and maeB that is a part of the MAL-pyruvate pathway. Therefore, the current perspective and review will discuss the potential efficacy of reducing antibiotic resistance by inhibiting genes that encode efflux protein pump expression while simultaneously upregulating metabolic genes for increased antibiotic uptake.
