Thesis Abstract

Abstract
The increasing prevalence of antibiotic resistance among pathogenic bacteria poses a significant threat to global public health. In light of this, the search for alternative antimicrobial agents has gained momentum, with natural plant extracts emerging as promising candidates. This thesis investigates the antimicrobial properties of natural plant extracts against common pathogenic bacteria, aiming to contribute to the development of novel antimicrobial strategies. Chapter One provides an introduction to the research topic, outlining 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 explores existing research on the antimicrobial properties of natural plant extracts, highlighting relevant studies on their efficacy against common pathogenic bacteria. Chapter Three details the research methodology, including the selection of plant extracts, bacterial strains, and antimicrobial assays used to evaluate their effectiveness. The methodology also encompasses extraction techniques, phytochemical analysis, and microbial susceptibility testing protocols. In Chapter Four, the findings of the study are discussed comprehensively. The antimicrobial activities of selected plant extracts against pathogenic bacteria are analyzed, considering factors such as minimum inhibitory concentrations, zone of inhibition, and mechanisms of action. The results provide valuable insights into the potential of natural plant extracts as alternative antimicrobial agents. Chapter Five presents the conclusion and summary of the thesis, offering a comprehensive overview of the research findings and their implications. The study underscores the importance of exploring natural sources for novel antimicrobial compounds and highlights the potential of plant extracts in combating antibiotic-resistant pathogens. Recommendations for future research directions are also provided to further advance the field of natural product-based antimicrobials. In conclusion, this thesis contributes to the growing body of knowledge on the antimicrobial properties of natural plant extracts against common pathogenic bacteria. By shedding light on the efficacy and mechanisms of action of these extracts, it offers valuable insights for the development of new antimicrobial strategies and underscores the importance of harnessing the potential of natural products in the fight against antibiotic resistance.
