[Histonet] Re: GMS fungus control

[Bob Richmond]

Clare J. Thornton, HTL(ASCP)QIHC at Dahl-Chase Diagnostic Services,
Bangor, Maine asks:

>>What is everyone using for their fungus control for GMS? We have always used pneumocystis when looking for pneumocystis, and Aspergillus when looking for fungus, but wondering if anyone uses any type of fungus just to see that stain worked properly. We are having difficulty locating tissue for both pneumo and Aspergillus, and are trying to avoid buying commercial QC slides.<<

It's preferable to have a pneumocystis control when needed.
Histoplasma is the best fungus control, when you can get it, because
it's the most difficult to stain. In ordinary surgical material,
aspergillus is most often seen in paranasal sinus material.
