Der Problemkeim Pseudomonas aeruginosa kann schwere Infektionen in verschiedenen Organen des menschlichen Körpers auslösen. Besonders gefährlich wird es, wenn sich die Bakterien zu Biofilmen zusammenlagern: So entziehen sie sich nicht nur Angriffen des Immunsystems, sondern schützen sich sogar vor der Wirkung von Antibiotika. Die Folge ist eine kaum behandelbare chronische Infektion. Wissenschaftler des Helmholtz-Instituts für Pharmazeutische Forschung Saarland (HIPS), einem gemeinsamen Standort des Helmholtz-Zentrums für Infektionsforschung (HZI) und der Universität des Saarlandes, haben ein Molekül entwickelt, das speziell an ein bakterielles Schlüsselprotein in Biofilmen bindet. Dieses Molekül blockiert dadurch einen wichtigen Baustein des Biofilms und kann gleichzeitig – wenn es uil vizdd wbfaoebpcivusp Xqeycrnpe zwukoihh sra – pup Yvaywog vk Kmhemh vgmsmloo lxizst.
