R. Fazion and F. A. Pires, RÉSUMÉ Bacillus cereus (Bc) et Bacillus thuringiensis (Bt) sont deux espèces génétiquement proches. Bc est une bactérie pathogène que peuvent causer des gastro-entérites d'origine aliméntaire. Bt est une bactérie entomopathogène, dont le cycle de vie dans la larve d'insecte est contrôlé par des systèmes de quorum sensing, comme le système Rap/Phr, que régule processus tels que la sporulation, la formation de biofilm et la conjugaison. La présence des ces genès a été identifiée dans les plasmides, Rôle des plasmides dans le groupe du B. cereus chez l'insect larvae, 2017.

, Pour la première étude l'insecte larvae, le niche privilegie de Bt, ont été infectées par souches de Bc et Bt, avec un contenu plasmidique diffèrent. Le fitness a été evallué par le comptage de cellules végétatives et spores dans quatre temps. Les souches de Bt et Bc ont été classées dans cinq groups par rapport à sont fitness, rôle des plasmides dans ces bactéries

, cereus que reçoivent a pathogène plasmid ne est pas suffisant pour une augmentation effectif de la population bactérienne, i.e., coloniser l'hôte. La deuxième étude a permis caractériser le système rap/phr porté par le plasmide cryptique pHT8_1. Les résultats démontrent que la protéine Rap8 inhibe la sporulation dans la l'insecte. L'activité de cette protéine est inhibée par le peptide de signalisation Phr8, Les résultats ont démontré que les souches du group du B

, un processus important pour assurer la survie et la dissémination des bactéries. L'ensemble des résultats de la deuxième étude montrent que les plasmides peuvent fournir avantages pour l'adaptation et evolution de B. thuringiensis dans son niche ecologique, alors que les résultats de la première étude indiqués que les souches de Bc group doivent avoir un contenu génétique approprié pour exhiber un fitness élévé en permettant une optimal multiplication and dissemination de populations bactérienne dans l, Rap/Phr8_1 a permis les bactéries exercer un strict contrôle sur la sporulation
