Infection of <i>Dictyostelium</i> (IMAGE) Université de Genève Caption Lipid droplets (blue) and membrane lipids (black) during the infection of Dictyostelium with mycobacteria. In wild-type cells, the host lipid droplets are recruited and used by mycobacteria. Alternatively, in a mutant Dictyostelium that cannot form lipid droplets, the bacillus exploits membrane lipids.
