[Helicobacter (Campylobacter) pylori in stomach and duodenal biopsies].

In bioptic specimens of the gastric mucosa of 57 patients with dyspeptic complaints and/or a duodenal ulcer Helicobacter pylori was detected under the microscope in 82,4% of chronic active gastritis and in 28,6% and 61,5% resp. of chronic gastritis grade I and II. The finding of helicobacteria depended on the number of collected specimens. They were never found at sites with intestinal metaplasia and their numbers did not correspond to the intensity and character of the inflammatory changes. As compared with the antrum, in the corpus of the stomach helicobacteria were found more frequently not only in mild forms of the inflammation but also in the normal mucosa. In the duodenum the finding was negative and the inflammatory changes were only mild. In all patients with a duodenal ulcer and a scar after ulceration in the antrum chronic active or inactive gastritis grade II was found with helicobacteria in 84,6% of the observations. Cultivation was consistent with microscopic evidence in 50 patients (87,7%).
