JF Journal of Clinical Pathology JO J Clin Pathol FD BMJ Publishing Group Ltd and Association of Clinical Pathologists SP 1072 OP 1073 DO 10.1136/jcp.48.11.1072 VO 48 IS 11 A1 Cellini, L A1 Allocati, N A1 Dainelli, B YR 1995 UL http://jcp.bmj.com/content/48/11/1072.abstract AB Stomach biopsies and samples of nasal mucus were cultured in patients with dyspeptic symptoms who underwent endoscopy to evaluate the possible route of transmission of Helicobacter pylori (H pylori). 42 patients were examined. For each patient two biopsies from the stomach corpus and antrum were taken and, before endoscopy, one nasal swab was obtained. Biopsy samples were tested for urease test, microbiological culture, and histological examination. The nasal swab was processed for microbiological examination. H pylori was not found in the nasal mucus of any of the patients, including the 36 who had H pylori in gastric biopsies.
