Subcellular colocalization in J774 cells of F. tularensis bacteria. J774 cells were infected for 2 h with F. tularensis strains and, after washing, incubated for 6 h. Bacteria were examined using transmission electron microscopy (TEM) and categorized into one of four categories depending on the preservation of the phagosomal membrane. At least 100 bacteria per sample were scored. Results from a representative experiment are shown.
