ABSTRACT:
The invention relates to a method for preparing closed bacterial ghosts by means of vesicle membrane fusion and to the bacterial ghosts which can be obtained in this way. Active compounds, e.g. genetic material, cell components, pharmaceutical and agricultural active compounds and also markers or dyes can be packaged in the closed bacterial ghosts. Metabolic functions and, where appropriate, the ability of the cells to proliferate can be restored on packaging genetic material in the bacterial ghosts. The closed ghosts can be used in medicine, in the agricultural sphere and in biotechnology.
