Figure 2From: Corynebacterium diphtheriae invasion-associated protein (DIP1281) is involved in cell surface organization, adhesion and internalization in epithelial cellsLIVE/DEAD staining of C. diphtheriae wild-type and mutant strains. Green fluorescent bacteria have a functional cytoplasmic membrane and are stained green, red propidium iodide staining indicates non-viable cells. A: ISS3319, B-C: Lilo1, D: ISS4060, E-F: Lilo2, C and F: cells subjected to 5 min of vigorous vortexing.Back to article page
