In the past we have given our micro dept. pieces of  unfixed umbilical cord
and let them incubate with gram positive, gram negative and fungus for a few
days. We then fix the tissue and process.

Subject: Special Stain Controls


Does any one have a procedure for making Special Stain controls by injecting
the "bugs" into fresh tissue? Our pathologist have limited the use of
diagnostic tissue blocks for control blocks.  We need to make some in-house
blocks.  The microbiology department will supply the  "bugs" but we need to
get them in the tissue and incubate the tilssue so we get a good control.
Any ideas?
Thank you,
