Thesis Overview

The project titled "Investigation of the antimicrobial properties of natural plant extracts against drug-resistant bacteria" aims to address the pressing issue of antibiotic resistance by exploring alternative treatment options using natural plant extracts. With the rise of drug-resistant bacteria posing a significant threat to public health, there is an urgent need to discover new antimicrobial agents that can effectively combat these resistant strains. The research will focus on investigating the antimicrobial properties of various natural plant extracts against drug-resistant bacteria. By utilizing plant extracts with potential antimicrobial activity, the study aims to identify novel compounds that can serve as effective alternatives to traditional antibiotics. This approach is particularly promising as natural products often exhibit diverse chemical structures and mechanisms of action, making them less prone to resistance development. The project will employ a multidisciplinary approach, combining techniques from microbiology, biochemistry, and pharmacology to evaluate the antimicrobial efficacy of plant extracts. Through in vitro studies, the research will assess the ability of these extracts to inhibit the growth of drug-resistant bacterial strains commonly encountered in clinical settings. Additionally, the investigation will delve into the mechanisms underlying the antimicrobial activity of the plant extracts, shedding light on their potential modes of action. Furthermore, the study will explore the synergistic effects of combining plant extracts with conventional antibiotics to enhance their antimicrobial activity. This synergistic approach has the potential to not only improve the efficacy of existing antibiotics but also reduce the likelihood of resistance development by targeting multiple bacterial pathways simultaneously. Overall, the research on the antimicrobial properties of natural plant extracts against drug-resistant bacteria holds great promise in the fight against antibiotic resistance. By uncovering new sources of antimicrobial agents and elucidating their mechanisms of action, this project aims to contribute valuable insights to the development of novel therapeutic strategies for combating drug-resistant bacterial infections.
