This scholarly book presents an integrative examination of Enterobacter and Salmonella, two clinically and economically significant bacterial genera that continue to pose challenges to both human and veterinary health. It combines the author’s original experimental work with comprehensive literature analysis to provide new insights into the molecular mechanisms of pathogenicity, antimicrobial resistance, and biofilm formation.The text explores the application of molecular tools such as 16S rRNA and rpoB gene sequencing for accurate bacterial identification and epidemiological tracing. Through an interdisciplinary lens, the book links laboratory findings to broader themes of zoonotic transmission, host-pathogen interaction, and public health preparedness.By aligning with the One Health framework endorsed by global institutions such as the WHO and CDC, this volume contributes to the international dialogue on antimicrobial stewardship and emerging infectious threats. It serves as a critical resource for postgraduate students, microbiologists, veterinarians, and researchers seeking an advanced understanding of bacterial adaptation and resistance in a global context.
