I'm not sure I understand your question.
What I think you want to know is how to determine if salmonellae
that have been ingested have been killed.
If so, there are some stain/dye procedures. THe macs are given an
opportunity to ingest the organism; then stained with (I don't recall
the specific reagent). Uner flourescent light you can distinguish
between the live and dead ingested bacteria.
Wish I could find the reference for you-- we have done it in our lab.
But, right now it just escapes my memory.
