Figure 6From: 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 cystsBacterial growth in dependence on the presence of T. pyriformis and LLO production. White and solid symbols show L. monocytogenes grown alone and in the presence of T. pyriformis, respectively; triangles and squares are correspondent to the EGDe and EGDeΔhly strains, respectively. Bacterial concentrations were determined by plating of corresponding dilutions. A representative experiment from two replicates with similar results is shown.Back to article page
