Histological examination of gastric tissue, culture, rapid urease testing, DNA probes, and PCR analysis, when used to test gastric tissue, all require endoscopy. pylori express significant urease activity, which appears essential to the survival and pathogenesis of the bacterium. pylori is able to colonize and persist in a unique biological niche within the gastric lumen. Transmission can occur by iatrogenic, fecal-oral, and oral-oral routes. There appears to be no substantial reservoir of H. In developed countries, the prevalence of infection is lower. In developing countries, 70 to 90% of the population carries H. pylori has been found in the stomachs of humans in all parts of the world. pylori, and we provide a background for appropriate chemotherapy of the infection.Ībstract = "Helicobacter pylori is a gram-negative bacterium which causes chronic gastritis and plays important roles in peptic ulcer disease, gastric carcinoma, and gastric lymphoma. In this review, we highlight advances in the detection of the presence of the organism and methods of differentiating among types of H. In contrast, breath tests, serology, gastric juice PCR, and urinary excretion of ammonia are noninvasive tests that do not require endoscopy.
