Fluorescent microscopy of C. jejuni 11168gfp4 cells. a. Fluorescent imaging of cells of wild-type C. jejuni NCTC 11168 and the 11168gfp4 strain expressing chromosomal gfp ^Cj driven by the C. jejuni promoter P _porA . b. Fluorescent imaging of gentamicin-treated HeLa cells, 3 h post-infection with C. jejuni NCTC 11168gfp4 expressing chromosomal gfp ^Cj driven by the C. jejuni promoter P _porA . Cells were stained with DAPI (blue) and phalloidin (red) with GFP fluorescence in green
