  2. Listeria monocytogenes - Wikipedia

    en.wikipedia.org/wiki/Listeria_monocytogenes

    Once inside the cell, L. monocytogenes rapidly acidifies the lumen of the vacuole formed around it during cell entry to activate listeriolysin O, a cholesterol-dependent cytolysin capable of disrupting the vacuolar membrane. This frees the pathogen and gives it access to the cytosol of the cell, where it continues its pathogenesis. [30]
