Abstract

Gastrospirillum hominis is a spiral-shaped bacterium found in the stomach. It has been implicated as a possible cause of chronic gastritis. We report two cases ofG. hominis colonization observed in a series of 175 healthy, asymptomatic volunteers investigated forHelicobacter pylori. None of the volunteers has symptoms or a history of gastrointestinal disease. Both carriers ofG. hominis had histological signs of chronic, active antral gastritis. Multiple tests forH. pylori were negative. The prevalence of this spiral bacterium in healthy, asymptomatic individuals may be as low as in symptomatic persons.
