Abstract

Cette invention concerne une molécule de signalisation, purifiée, extracellulaire, d'origine bactérienne, appelée autoinducteur 2 dont la production est régulée par des modifications environnementales accompagnant le passage d'une existence libre à une existence colonisatrice ou pathogène dans un organisme hôte. La molécule de signalisation stimule des gènes de luminescence LuxQ et, apparemment, divers gènes en rapport avec la pathogenèse dans l'espèce bactérienne qui produit ladite molécule. Cette invention concerne également une nouvelle classe de gènes bactériens intervenant dans la biosynthèse de la molécule de signalisation.
