[Histonet] Re: Fite control block

[Robert Richmond]

Kimberly Artim, AST, HT (ASCP), Technical Coordinator, Anatomic
Pathology, St Lukes Hospital & Health Network, Bethlehem, Pennsylvania
asks about a Fite control block.

Do you mean a block of tissue with Mycobacterium leprae?

It's preferable indeed to have lepra bacilli rather than tubercle
bacilli in the control, since the two organisms stain somewhat
differently. Obviously human tissue is extremely rare. Does anyone use
leprous armadillo (Dasypus novemcinctus) tissue as a control? Does
anyone know how to get it?
