Pour étudier la réponse physiologique in vivo de l'intestin de drosophile à l'ingestion d'une bactérie, nous avons besoin de dénombrer les bactéries dans l'intestin qu'elles soient exogènes ou commensales. Pour cela, nous avons mis au point une méthode fondée sur des techniques de microbiologie ainsi que des techniques d'intoxication et de...

When sporulating, Bacillus thuringiensis produces paracrystalline inclusions containing one or more proteins which are mainly responsible for the entomopathogenic properties of this bacterium. Such proteins mostly belong to the Cry family which, after spore lysis and solubilization of the crystals, are delivered to specific zones of the gut....
