Thesis Abstract

Abstract
Natural plant extracts have long been recognized for their potential antimicrobial properties, providing a rich source of bioactive compounds that can combat pathogenic bacteria. This thesis presents a comprehensive investigation into the antimicrobial properties of selected natural plant extracts against pathogenic bacteria. The study aims to evaluate the efficacy of these plant extracts as potential alternatives to conventional antibiotics, in response to the growing concern of antibiotic resistance. The introduction provides an overview of the rising threat of antibiotic resistance and the need for alternative antimicrobial agents. The background of the study delves into the historical use of natural plant extracts in traditional medicine and their potential as novel antimicrobial agents. The problem statement highlights the urgent need for new antimicrobial strategies to combat drug-resistant bacteria, emphasizing the importance of exploring natural sources. The objectives of the study are outlined to assess the antimicrobial activity of selected plant extracts against a panel of pathogenic bacteria, including both Gram-positive and Gram-negative strains. The limitations of the study are acknowledged, such as variations in plant extract composition and potential interactions with bacterial species. The scope of the study defines the parameters of the research, focusing on in vitro antimicrobial assays and phytochemical analysis of the plant extracts. The significance of the study lies in its potential to contribute to the development of new antimicrobial agents from natural sources, addressing the global health challenge of antibiotic resistance. The structure of the thesis provides a roadmap for the reader, outlining the chapters and sub-sections that will be covered in detail. Definitions of key terms are provided to clarify the terminology used throughout the thesis. The literature review explores existing research on the antimicrobial properties of natural plant extracts, highlighting key studies and findings in the field. The research methodology details the experimental design, including extraction methods, microbial strains used, and antimicrobial assays performed. The discussion of findings presents the results of the antimicrobial tests, analyzing the effectiveness of the plant extracts against different bacterial species. In conclusion, this thesis offers valuable insights into the antimicrobial properties of natural plant extracts and their potential as alternative agents against pathogenic bacteria. The summary highlights the key findings of the study and their implications for future research and the development of novel antimicrobial therapies. Overall, this research contributes to the growing body of knowledge on natural antimicrobial agents and their role in combating antibiotic resistance.
