From: Listeria monocytogenes virulence factor Listeriolysin O favors bacterial growth in co-culture with the ciliate Tetrahymena pyriformis, causes protozoan encystment and promotes bacterial survival inside cysts

Figure 2

Changes in the T. pyriformis population in the presence or absence of L. monocytogenes. Trophozoite concentrations are shown by polylines; cyst concentrations are shown by bars. Protozoa were grown alone (white) or in co-culture with the L. monocytogenes strain EGDe (solid). The mean values ± SD from three experiments made in triplicate are shown.
