Preface
Since the third edition of Bacterial Pathogenesis: A Molecular Approach was written, the field of bacterial pathogenesis has vastly expanded and evolved. Some areas have been revolutionized by the manner that research is now conducted in this genome era and the wealth of information obtained from modern advanced technologies, while other areas have become obsolete. These changes have necessitated extensive updating and rewriting of many chapters of the textbook. The death of Abigail Salyers and the retirement of Dixie Whitt in 2013 necessitated the recruitment of a new author, Brian Ho, who like the other remaining authors, Brenda Wilson and Malcolm Winkler, comes with significant expertise and research experience in modern approaches to studying bacterial pathogenesis.
This textbook is intended to be a living book that evolves in response to the constantly changing research landscape of the field of bacterial pathogenesis. True to this mandate, the
