Thesis Abstract

Abstract
This thesis presents a comprehensive investigation into the antimicrobial properties of natural plant extracts against pathogenic bacteria. The increasing prevalence of antibiotic resistance among pathogenic bacteria poses a significant global health threat, highlighting the urgent need for alternative antimicrobial agents. Natural plant extracts have been recognized for their potential antimicrobial properties, making them promising candidates for the development of new antimicrobial agents. This study aims to evaluate the effectiveness of selected natural plant extracts in inhibiting the growth of pathogenic bacteria and elucidate the underlying mechanisms of their antimicrobial activity. Chapter One provides an introduction to the research topic, discussing the background of the study, problem statement, objectives, limitations, scope, significance, structure of the thesis, and definition of key terms. The literature review in Chapter Two examines existing research on natural plant extracts with antimicrobial properties, highlighting their potential applications in combating pathogenic bacteria. Chapter Three outlines the research methodology, including the selection of plant extracts, experimental design, microbial strains used, extraction techniques, and antimicrobial assays. Chapter Four presents a detailed discussion of the findings, including the antimicrobial activity of the selected plant extracts against pathogenic bacteria, the minimum inhibitory concentrations (MICs), and the potential mechanisms of action. The results indicate that certain plant extracts exhibit significant antimicrobial activity, suggesting their potential as alternative antimicrobial agents. In the conclusion and summary in Chapter Five, the key findings of the study are summarized, and the implications for future research and applications are discussed. Overall, this thesis contributes to the growing body of knowledge on the antimicrobial properties of natural plant extracts and highlights their potential as effective antimicrobial agents against pathogenic bacteria. Further research in this area is warranted to explore the full potential of natural plant extracts in addressing the global challenge of antibiotic resistance.
