Apoptosis of Epithelial Cells and Macrophages due to Nonpigmented Serratia marcescens Strains

Figure 2

Apoptosis of HEp-2 cells. The cells were stained with ethidium bromide and acridine orange (100 μg/mL) and observed in a laser confocal microscope. The cells were infected with (a) E. coli K-12 C600, (b) S. marcescens MPU S23 at 48 h. The arrows point to: a: live, b: apoptotic with apoptotic bodies, c: necrotic cells.
