We use now Loeffler's stain (methylene blue) for
H.pylori. It is very quickly and simply method.
We use oil immersion for value. We have 3-16 GI bx
daily (every gastric biopsy stain H&E, AB-PAS and
Loeffler; we do not IHC).
I also seen few times Helicobacter heilmannii in
past year. And we never used H&E for values
