Für mehr als fünf Millionen Menschen haben Magen-Darm-Erkrankungen jedes Jahr tödliche Folgen. Braunschweiger Forscher haben jetzt herausgefunden, was einen Stamm von Yersinia pseudotuberculosis - einer der Hauptverursacher dieser Infektionen - so gefährlich macht: Die Bakterien produzieren ein Molekül namens CNFy, das ihnen die Infektion erleichtert. Es verändert die Wirtszellen in einer Weise, dass der Injektionsapparat von Yersinia, der Giftstoffe in die Zellen spritzt, effektiver arbeiten kann. Dies verstärkt die Infektion und führt zu Entzündungen des Gewebes.
