The GFP expression pattern looked like that observed for strain UL3241, transgenic for fUL#JW166, with the same reporter gene fusion arrangement but in a different fosmid background.
This operon, when introduced as a transgene, fully restored bacterial adhesion and tail swelling to infected animals, and exhibited the same expression in cells K, F, and U, with a diffuse cytoplasmic distribution of the GFP reporter.
