Thesis Overview

The project titled "Investigating the Antimicrobial Properties of Plant Extracts Against Pathogenic Bacteria" aims to explore the potential of plant extracts as natural antimicrobial agents against pathogenic bacteria. In recent years, the rise of antibiotic resistance has become a major global health concern, highlighting the urgent need for alternative antimicrobial strategies. Plant extracts have long been used in traditional medicine for their therapeutic properties, and their antimicrobial activities have gained significant attention in scientific research. This research will focus on investigating the antimicrobial properties of selected plant extracts against a range of pathogenic bacteria commonly associated with human infections. The study will involve the extraction of bioactive compounds from various plant sources using different extraction methods. These plant extracts will then be tested for their antimicrobial efficacy through various in vitro assays, including agar diffusion and broth microdilution methods. The project will also explore the mechanisms of action underlying the antimicrobial activity of the plant extracts, aiming to elucidate the interactions between the bioactive compounds and bacterial cells. Understanding these mechanisms is crucial for developing novel antimicrobial agents and combating antibiotic resistance effectively. Furthermore, the research will evaluate the potential synergistic effects of combining plant extracts with conventional antibiotics, aiming to enhance the antimicrobial activity and overcome resistance mechanisms. This approach may lead to the development of combination therapies that could improve treatment outcomes and reduce the emergence of resistance in pathogenic bacteria. Overall, this project seeks to contribute to the growing body of knowledge on natural antimicrobial agents and their potential applications in combating infectious diseases. By harnessing the antimicrobial properties of plant extracts, this research aims to provide valuable insights that could pave the way for the development of new therapeutic strategies against pathogenic bacteria.
