Eine am Helmholtz-Zentrum für Infektionsforschung (HZI) in Braunschweig entdeckte Gruppe von antibiotischen Naturstoffen zeigt einen neuen Wirkmechanismus gegen krankmachende Bakterien. Die aus Myxobakterien isolierten Substanzen verhindern, dass Enzyme der Krankheitserreger deren Erbmaterial ablesen können. Die Vermehrung der Bakterien - wie beispielsweise Tuberkulose-Erreger - wird so gestoppt. Eine US-amerikanische Arbeitsgruppe der Rutgers-Universität in New Jersey hat jetzt zusammen mit HZI-Forschern herausgefunden, dass die Substanzen in den Bakterien an einer anderen Stelle wirken als alle bisher bekannten Antibiotika - wie etwa das Rifamycin, ein Standardmedikament gegen Tuberkulose. Diese Erkenntnis macht die Braunschweiger Naturstoffe zu äußerst interessanten Kandidaten für die Antibiotika-Entwicklung - zumal uwf Wyenvkmida ivne czahcofpzvy-aciabmpxze Vvgqvjzdockkfvp xtjbaps.
