How would you determine whether a colorless colony on MacConkey agar is Salmonella or Shigella? Why would you want to identify a colorless colony?

Salmonella has Lysine DeCarboxylase, whereas Shigella does not.
Some people would argue that you could just treat such an infection with ciprofloxacin and who needed to know what the bacteria was called anyway ...
CDC and most doctors would be curious and would require a microbiologist to give them an answer.
Why would we want to know if our treatment is just going to be the same? I guess it's because we feel that we can more accurately track outbreaks and disease patterns and change in the behaviour of an organism if we accurately classify it. Particularly with respect to antibiotic resistance.
