I quite often see faint cytoplasmic staining in immunostains for Helicobacter. You're supposed to ignore it. It's often present in the negative control slide - one of the few reasons I ever look at a negative control slide.
These days I get my IHC for Helicobacter from whatever Genzyme is called this week. I'm noticing considerably less cytoplasmic staining than I've usually seen before.
