Hi, We are using a regular Giemsa stain for H. Pylori, but may soon be 
identifying these organisms using IHC.  We are looking into this.  One 
pathologist likes the Genta stain, which is a silver stain, but is a much 
longer procedure than the Giemsa.We have another pathologist who asked about 
the Alcian Yellow stain (which we do not have), and he said he used it at 
Stanford.  I think a little while ago, there was a reference on Histonet 
about this stain.  Good luck!
