Book

E. coli O157:H7: Molecular Pathogenesis and Public Health presents a rigorous and integrative exploration of one of the most consequential foodborne pathogens in modern public health. This volume synthesizes advances in microbiology, molecular genetics, epidemiology, and clinical science to provide a comprehensive understanding of the organism’s biology and its global impact. Beginning with the taxonomic and physiological foundations of Escherichia coli, the book systematically examines the emergence of O157:H7 as a high-risk Shiga toxin–producing strain. Detailed chapters elucidate the molecular architecture of virulence, including Shiga toxins, the locus of enterocyte effacement (LEE), type III secretion systems, and plasmid-mediated factors that drive host–pathogen interactions and disease severity. The text further addresses transmission dynamics across food systems, animal reservoirs, and environmental pathways, highlighting the complexity of outbreak patterns in both developed and emerging economies. Clinical sections provide in-depth discussion of hemorrhagic colitis, hemolytic uremic syndrome (HUS), and associated complications, supported by current diagnostic approaches ranging from culture-based methods to advanced molecular and genomic technologies. Importantly, this book bridges science and application by examining contemporary strategies in treatment, risk management, and prevention, including HACCP-based food safety systems, surveillance frameworks, and emerging biotechnological interventions. Emphasis is placed on translational insights that inform policy, laboratory practice, and global health preparedness. Designed for researchers, clinicians, food safety professionals, and advanced students, this reference work offers both foundational knowledge and cutting-edge perspectives. As the burden of foodborne disease continues to evolve in an era of globalization and climate change, this volume provides a critical resource for understanding and mitigating the risks posed by E. coli O157:H7.
