Figure 4From: Strain-specific differences in pili formation and the interaction of Corynebacterium diphtheriae with host cellsTransepithelial resistance of polarized D562 monolayers grown on transwells. (A) Control experiments of cells, which were incubated without bacteria (open circles) and S. enterica serovar Typhimurium (open squares). (B) Incubation with C. diphtheriae strains DSM43989 (tox+, open stars), ISS4749 (inverted closed triangles), ISS4746 (closed triangles), ISS4060 closed circles, ISS3319 (closed square), DSM43988 (closed hexagons), and DSM44123 (closed diamonds). Experiments were carried out independently at least thrice and typical results are shown.Back to article page
