Thesis Abstract

Abstract
The human gut microbiota plays a crucial role in maintaining health and impacting various disease states. Inflammatory Bowel Disease (IBD) is a group of chronic inflammatory conditions affecting the gastrointestinal tract, characterized by dysregulated immune responses. This thesis aims to explore the intricate relationship between gut microbiota and IBD, focusing on the mechanisms underlying disease pathogenesis, potential biomarkers, and therapeutic interventions targeting the microbiota. Chapter One provides an introduction to the topic, presenting background information on the gut microbiota, the prevalence of IBD, and the need for further research in this area. The problem statement highlights the gaps in current knowledge regarding the specific roles of gut microbiota in IBD pathogenesis. The objectives of the study are to investigate the impact of gut dysbiosis on IBD development, identify potential microbial biomarkers for disease diagnosis and prognosis, and evaluate microbiota-targeted therapies. Limitations and scope of the study are outlined, emphasizing the focus on human studies and the need for further clinical trials. The significance of the study lies in its potential to enhance our understanding of IBD pathophysiology and improve therapeutic strategies. The structure of the thesis is also detailed, providing an overview of the chapters and sub-sections. Chapter Two comprises a comprehensive literature review, covering ten key aspects related to gut microbiota and IBD. Topics include the role of specific bacterial species in IBD pathogenesis, the influence of diet on gut microbiota composition, and the impact of microbial metabolites on immune responses in the gut. Chapter Three outlines the research methodology, including study design, participant selection criteria, sample collection methods, and laboratory techniques for microbiota analysis. Additional sections discuss data analysis procedures, statistical methods, and ethical considerations in human research. In Chapter Four, the findings of the study are discussed in detail, focusing on the relationship between gut microbiota composition, immune dysregulation, and IBD severity. Potential microbial biomarkers for disease diagnosis and prognosis are identified, and the efficacy of microbiota-targeted therapies is evaluated based on clinical outcomes. Chapter Five presents the conclusion and summary of the thesis, highlighting key findings, implications for clinical practice, and recommendations for future research directions. Overall, this thesis contributes to the growing body of evidence supporting the critical role of gut microbiota in IBD pathophysiology and provides insights into novel therapeutic strategies for managing this complex disease.
