Infection biology: What makes Helicobacter so adaptable?

The cosmopolitan bacterium Helicobacter pylori, which colonizes the mammalian gastrointestinal system, is responsible for one of the most common microbial infections in humans. Many Helicobacter infections provoke no overt symptoms, while others induce various types of gastrointestinal disorders, such as gastric ulcers. However, the most serious consequence of infection with H. pylori is that the microorganism can induce the development of cancer of the stomach. One of the most striking features of the species is its genetic diversity. Research groups led by microbiologists Professor Sebastian Suerbaum and Professor Christine Josenhans at LMU's Max von Pettenkofer Institute have been exploring the significance of this feature for its ability to survive in its human hosts. They now report the identification of a particular enzyme that plays an important role in coordinating the regulation of gene expression in the pathogen. The protein belongs ...
