Immunocytochemical identification of Helicobacter pylori in formalin-fixed gastric biopsies.

Abstract

H&E and special histochemical stains are used by most laboratories to identify Helicobacter pylori (H. pylori) in gastric biopsy specimens. However, background staining can complicate recognition of H. pylori and small numbers of organisms may be overlooked. Additionally, histochemical stains do not distinguish H. pylori from other spiral organisms. We… (More)
