Abstract
The burgeoning proliferation of infections attributed to multidrug-resistant (MDR) bacterial pathogens is profoundly undermining conventional chemotherapeutic modalities, portending a grave menace to global public health. The propagation of drug resistance among bacteria is fundamentally facilitated by bacterial interactions, with extracellular vesicles (EVs) assuming a critical role in interbacterial communication. Here, we briefly delineate the methodologies for isolation, extraction, and characterization of EVs from both Gram-negative and Gram-positive bacterial origins. We further investigate assorted methodologies to augment EV production, embracing physical stimulation, chemical elicitation, and genetic engineering. Moreover, we expound on the pivotal involvement of EVs in the facilitation of bacterial drug resistance proliferation and anticipate future trajectories of research and application potential. This overview of EV-mediated novel mechanisms of horizontal gene transfer implicated in antibiotic resistance among bacteria aims to obstruct the transmission conduits of bacterial drug resistance and thus fortify public health integrity.
