title: Immunocytochemical study of Helicobacter pylori in the mucosae of the gastric antrum and rectum.
abstract: We present the results of bacterioscopic and immunocytochemical study of Helicobacter pylori in biopsy specimens from the gastric antrum and smears from the rectum. Predominance of spiral-shaped vegetative form of Helicobacter pylori in the antrum and the presence of cocci with Helicobacter pylori antigens in smears from the rectum were demonstrated in patients infected with Helicobacter pylori. The diagnostic sensitivity of non-invasive immunocytochemical Helicobacter pylori test in rectal smears was 90%, specificity 76%, and efficiency of the test 84%.
