Thesis Overview

The project titled "Investigating the Antibacterial Properties of Plant Extracts against Drug-Resistant Bacteria" aims to address the pressing issue of antibiotic resistance by exploring alternative sources of antimicrobial agents. The rise of drug-resistant bacteria poses a significant threat to public health, necessitating the search for novel strategies to combat bacterial infections. Plants have long been recognized for their diverse bioactive compounds, some of which exhibit potent antibacterial properties. This research project seeks to investigate the potential of plant extracts as alternative antimicrobial agents against drug-resistant bacteria. The study will begin with a comprehensive literature review to establish the current understanding of antibiotic resistance, the mechanisms involved, and the challenges it presents to healthcare. This will provide the necessary background information to support the rationale for exploring plant extracts as a potential solution. The literature review will also explore previous studies on the antibacterial properties of plant extracts, highlighting promising leads for further investigation. The research methodology will involve the collection of plant samples from diverse sources, followed by extraction of bioactive compounds using appropriate solvents and extraction techniques. The antibacterial activity of these extracts will be evaluated using standard microbiological techniques, such as agar diffusion assays and broth microdilution method. The study will focus on a panel of drug-resistant bacteria commonly encountered in clinical settings, including MRSA, ESBL-producing Enterobacteriaceae, and multidrug-resistant Pseudomonas aeruginosa. The findings of the study will be presented in the form of a detailed discussion, analyzing the effectiveness of different plant extracts against the target bacteria. The mechanisms of action underlying the antibacterial activity of these extracts will be explored, providing insights into their potential as future antimicrobial agents. The discussion will also highlight any synergistic effects observed between different plant extracts or in combination with conventional antibiotics. In conclusion, this research project aims to contribute to the growing body of knowledge on alternative antimicrobial agents and provide valuable insights into the potential of plant extracts in combating drug-resistant bacteria. By exploring the antibacterial properties of plant extracts, this study seeks to offer new avenues for the development of novel antimicrobial therapies that could help address the global challenge of antibiotic resistance.
