RE: Gram stain controls

From:Walzer Susan

We give our micro dept. fresh sections of umbilical cord and they incubate
them with each positive and negative bacteria for a couple of days. We then
fix them in formalin and process and embed one piece of each in a block. Any
fresh tissue would work I think, but it shows up well on the cord tissue.

Does anyone have experience with making their own gram positive and negative
controls from cultures?  If so, would you share your experiences and
procedures?  I thought it would be nice to have gram positive cocci and gram
negative rods.  Thanks for any and all help.
