In Europa entvölkerte die Pest einst ganze Landstriche, in Afrika, Südamerika und Indien tritt sie noch heute immer wieder auf. Die Erreger der Seuche sind Bakterien der Gattung Yersinia. Etwas weniger aggressive Verwandte dieses Erregers lösen auch in Deutschland jedes Jahr mehrere Tausend Fälle von Durchfallerkrankungen mit teilweise schweren Folgeerscheinungen aus. Wissenschaftler des Braunschweiger Helmholtz-Zentrums für Infektionsforschung (HZI) haben gemeinsam mit Kollegen der Ruhr-Universität Bochum einen Mechanismus entdeckt, wie diese Bakterien ihre Waffen im Wirt anschalten. Der Trick: Yersinien besitzen ein molekulares Thermometer, das nur bei 37 Grad Celsius das krankmachende Programm der Bakterien startet.
