The recent completion of the genome sequences of several Salmonella serovars, allied with the application of whole genome analyses, and the availability of meaningful infection models in target animal species have contributed greatly to recent progress in the understanding of the molecular genomics and cellular biology of this family of complex pathogens. In this book internationally acclaimed experts review cutting-edge topics in Salmonella research. Chapters are written from a molecular perspective and provide a unique insight into the current status of Salmonella research. Topics include epidemiology, molecular typing, antibiotic resistance, host-interaction in the gut, adhesins, pathogenecity islands, virulence plasmids, gene regulation, biofilms, and microarray analysis.
