Helicobacter pylori infection is an important factor in the development of gastric carcinogenesis, but only a fraction of infected patients will develop gastric cancer. The aim of this research is to investigate the prevalence of H. pylori infection among dyspeptic patients of Nova Iguaçu city, province of Rio de Janeiro, Brazil. The research design is observational, retrospective and cross-sectional. The universe consisted of 56 patients of both genders aged over 25 years. Between January 2015 and July 2016, fragments of the lesions suggestive of H. pylori infection were collected through digestive endoscopy. The biopsy specimens were analyzed in a pathological anatomy laboratory and the validation of the infection was confirmed by the morphotintorial characteristics of the bacteria and biological tests: arched Gram negative bacilli through anatomopathological examination and positive urease test. Among patients suspected of H. pylori infection, 12 (21.4%) were positive. The infection was confirmed in dyspeptic patients in the studied region. The prevalence is below the global values, where 50% of the population is a pathogenous carrier. There were no significant differences between infection and gender correlation. Positivity was higher in people between the ages of 41 and 50 years.
