Gastric Helicobacter pylori infection perturbs human oral microbiota
Background We investigated the effects of gastric Helicobacter pylori infection on the daytime and overnight human oral microbiota. Methods Twenty four volunteers were recruited. Ten tested positive for H. pylori infection by the Carbon-14 Urea Breath Test, and the rest were negative. Two oral swabs...
