title: Non classical secretion systems.
abstract: Bacteria use molecular machines or weapons to colonize, invade or fight other bacteria and eukaryotic cells. In addition to these various secretion systems, two different systems that release bacterial compounds have also been described. The first one corresponds to membrane vesicle formation and to long distance delivery of membrane or soluble components. The second system is dependent of the expression of the colicin lysis genes known for releasing cytoplasmic colicins as well as other soluble proteins. Both systems will be described thereafter.
