Thesis Abstract

Abstract
The rise of drug-resistant bacteria poses a significant threat to public health worldwide. In the face of this challenge, the search for alternative antimicrobial agents has become crucial. Plant extracts have long been recognized for their therapeutic properties, including antimicrobial effects. This thesis presents an investigation into the antimicrobial properties of plant extracts against drug-resistant bacteria. The study aims to evaluate the efficacy of various plant extracts in inhibiting the growth of drug-resistant bacterial strains, with a focus on understanding the underlying mechanisms of action. Chapter One provides an introduction to the research topic, discussing the background of the study, the problem statement, objectives, limitations, scope, significance, structure of the thesis, and key definitions. Chapter Two presents a comprehensive literature review, analyzing previous studies on the antimicrobial properties of plant extracts and their effectiveness against drug-resistant bacteria. The review covers various plant species, extraction methods, bioactive compounds, and mechanisms of action involved. Chapter Three details the research methodology employed in this study, including the selection and preparation of plant extracts, bacterial strains used, antimicrobial susceptibility testing methods, and data analysis techniques. The chapter also describes the experimental design and procedures followed to evaluate the antimicrobial activity of plant extracts against drug-resistant bacteria. Chapter Four presents a thorough discussion of the findings obtained from the study. The results of antimicrobial susceptibility testing are analyzed, highlighting the effectiveness of different plant extracts against drug-resistant bacterial strains. The mechanisms of action of the plant extracts are explored, shedding light on their potential as alternative antimicrobial agents. The chapter also discusses the implications of the findings for future research and clinical applications. In Chapter Five, the conclusion and summary of the thesis are provided. The key findings of the study are summarized, and the implications for addressing the challenge of drug-resistant bacteria are discussed. Recommendations for further research are made, emphasizing the importance of exploring the potential of plant extracts as novel antimicrobial agents. Overall, this thesis contributes to the growing body of knowledge on alternative antimicrobial strategies and highlights the potential of plant extracts in combating drug-resistant bacterial infections.
