The research problem addressed in this thesis is the time-consuming nature of conventional microbiological methods, which often delay the initiation of targeted therapy in infected patients. By leveraging the high-throughput capabilities of NGS, this study aims to streamline the identification process and enable timely intervention for better clinical outcomes. The objectives of the study include evaluating the performance of NGS in pathogen identification, comparing its accuracy and speed with traditional methods, and assessing the feasibility of integrating NGS into routine diagnostic workflows in clinical laboratories. Additionally, the study aims to identify the limitations and challenges associated with NGS implementation in diagnostic microbiology and propose solutions to overcome these obstacles. The scope of the study encompasses a review of relevant literature on NGS applications in microbiology, an analysis of different NGS platforms and bioinformatics tools available for pathogen identification, and a comparative evaluation of NGS with conventional diagnostic methods in terms of sensitivity, specificity, and turnaround time. The significance of this research lies in its potential to revolutionize diagnostic microbiology practices, leading to faster and more accurate identification of pathogens, reduced healthcare costs, and improved patient outcomes. By providing a structured framework for the implementation of NGS in clinical settings, this study aims to contribute to the advancement of precision medicine and personalized treatment strategies. The thesis is structured into five chapters, with Chapter 1 providing an introduction to the research topic, background information on NGS technology, a problem statement, research objectives, limitations, scope, significance of the study, and the thesis structure. Chapter 2 presents a comprehensive literature review covering ten key aspects of NGS applications in diagnostic microbiology. Chapter 3 details the research methodology, including sample collection, NGS workflow, data analysis, and validation procedures. Chapter 4 discusses the findings of the study, highlighting the performance of NGS in pathogen identification and comparing it with traditional methods. Finally, Chapter 5 presents the conclusion and summary of the thesis, emphasizing the implications of the research findings and suggesting future directions for further research in this field. In conclusion, the implementation of Next-Generation Sequencing in diagnostic microbiology holds great promise for revolutionizing pathogen identification and improving patient care. This thesis contributes to the growing body of knowledge on NGS applications in clinical microbiology and provides valuable insights for healthcare professionals, researchers, and policymakers seeking to enhance diagnostic capabilities in infectious disease management.
