Dear Dr. Ahmed,

May I recommend to you that you try the Steiner stain for spirochetes FIRST?
It is so much easier to do than W/S, and the results are wonderful.  It is a
pretty common stain here, especially for H. pylori.   A kit is available from
Poly Scientific, although I mix my own reagents (relatively simple!).

Good luck,
