Introductory chapters explore the taxonomy, genetic diversity, habitats, and epidemiological analysis of campylobacters. Other chapters review Campylobacter plasmid biology, antimicrobial resistance, stress response, motility, chemotaxis, metabolism and bioenergetics of C.jejuni, and polysaccharide biosynthesis (including lipooligosaccharide, capsule biosynthesis, and protein glycosylation). The final chapters focus more directly on interactions with the host, for example, the mechanisms of host cell invasion, interactions with phagocytes, and the use of microarrays to analyze gene expression in response to infection by C jejuni.
