Table 1 Adhesion of C. diphtheriae to epithelial cells and internalization. D562 cells (2 × 105 cells per well) were infected with C. diphtheriae (4 × 107 cfu/ml) leading to a multiplicity of infection (MOI) of 200.

From: Corynebacterium diphtheriae invasion-associated protein (DIP1281) is involved in cell surface organization, adhesion and internalization in epithelial cells
