Thesis Abstract

Abstract
Microbial infections caused by pathogenic bacteria continue to pose significant challenges to healthcare systems worldwide. The emergence of antibiotic resistance has further complicated the treatment of these infections, necessitating the exploration of alternative antimicrobial agents. Plant extracts have long been recognized for their diverse bioactive compounds with potential antimicrobial properties. This thesis investigates the antimicrobial properties of plant extracts against pathogenic bacteria with the aim of identifying novel natural compounds for combating bacterial infections. Chapter One provides an introduction to the study, offering insights into the background of the research, the problem statement, objectives, limitations, scope, significance, structure of the thesis, and definitions of key terms. The chapter sets the stage for the subsequent discussions on the antimicrobial potential of plant extracts. Chapter Two presents a comprehensive literature review encompassing ten key areas related to antimicrobial activities of plant extracts against pathogenic bacteria. This review synthesizes existing knowledge on the subject, highlighting gaps in the literature and paving the way for the research methodology. Chapter Three details the research methodology employed in this study, including the selection and preparation of plant extracts, bacterial strains used, antimicrobial screening techniques, data collection methods, and statistical analysis procedures. This chapter outlines the systematic approach taken to evaluate the antimicrobial efficacy of plant extracts. Chapter Four delves into the discussion of findings, presenting the results of antimicrobial activity assays, elucidating the mechanisms of action of active compounds in plant extracts, and exploring potential synergistic effects. The chapter critically analyzes the data, interprets the results, and discusses the implications of the findings in the context of bacterial infection management. Chapter Five serves as the conclusion and summary of the thesis, encapsulating the key findings, implications for future research, and practical applications of the study. This chapter synthesizes the research outcomes, provides recommendations for further investigation, and underscores the significance of utilizing plant extracts as alternative antimicrobial agents. In conclusion, this thesis contributes to the growing body of knowledge on the antimicrobial properties of plant extracts against pathogenic bacteria. By identifying and elucidating the mechanisms of action of bioactive compounds in plant extracts, this study offers insights that can inform the development of novel antimicrobial agents for combatting bacterial infections and addressing the global challenge of antibiotic resistance.
