Molecular microbiology and pathogenesis of Helicobacter and Campylobacter updated: a meeting report of the 11th conference on Campylobacter, Helicobacter and related organisms.
The genome analysis of the gastrointestinal pathogens Helicobacter and Campylobacter has stimulated a wealth of new research activities, which are presented every 2 years at the international conferences on Campylobacter, Helicobacter and Related Organisms (CHRO). Both organisms represent excellent models for the identification of new molecular mechanisms involved in pathogenesis, host response and physiological adaptation in course of acute and chronic infectious diseases. The investigation of their global distribution, pronounced genetic and antigenic diversity as well as the molecular mechanisms allowing long-term persistence in hostile and unusual microbial habitats, is a challenge for scientists of many different disciplines world-wide. With a focus on the molecular microbiology aspects, this review summarizes recent trends in Helicobacter and Campylobacter research by highlighting selected presentations at the 11th CHRO conference. The topics include the discovery of new virulence factors, functional analysis of protein secretion systems, host signalling pathways, adaptation to stress conditions, global gene regulation, and genetic variability.
