[The determination of C. pylori in patients with gastroduodenal diseases]

A total of 46 gastric mucosa biopsy specimens obtained during surgery and 90 gastric juice samples from patients with gastroduodenal diseases were examined. Campylobacter-like microorganisms were detected in 84.6 percent of biopsy specimens and in 73.9 percent of gastric juice samples (in gram-stained smears). Urease activity was detected in 75.9 and 13.3 percent, respectively. C. pylori growth in solid nutrient medium in microaerophilic conditions was observed in 44.2 and 5.7 percent of the examined samples, respectively. The studies have demonstrated the efficacy of using disks with urea from standard kits manufactured by the Research Institute for Epidemiology and Microbiology in the city of Gorky in the urease test.
