• Sommario/riassunto: Members of the genus Campylobacter are commonly found in the gastrointestinal tract of mammals and birds, and can be commensal or pathogenic in nature. For example, Campylobacter jejuni can be a harmless commensal organism in poultry and other avian and animal hosts, but in humans, it is pathogenic and the most common cause of bacterial gastroenteritis worldwide. In recent years, the application of DNA sequencing and 'omics' technologies to large numbers of isolates has allowed Campylobacter research to advance rapidly, revealing fascinating new insights into the cellular biology and evolution
