Where Does Helicobacter pylori Come From and Why Is It Going Away?
Article Abstract:
Improved sanitation and housing conditions may account for the gradual disappearance of Helicobacter pylori during the 20th century. This bacterium has been linked to peptic ulcer disease and stomach cancer. It appears to live in the stomach and many people are exposed in childhood. It only occurs in humans but other animals have similar bacteria in their stomachs. It is possible that it has been infecting humans and our primate ancestors for millions of years. A 1999 study found that it may be transmitted in vomit and feces. There is evidence that the bacterium is gradually disappearing in developed countries.

Fecal and Oral Shedding of Helicobacter pylori From Healthy Infected Adults
Article Abstract:
Helicobacter pylori can be transmitted in saliva and possibly in feces. Helicobacter pylori is a bacterium that has been linked to heartburn and peptic ulcers. Researchers gave 16 people infected with the bacterium a drug to make them throw up and then tested the vomit for the presence of the bacterium. All of the samples of vomit tested positive and saliva samples taken before and after vomiting also tested positive. Twenty-two percent of the stool samples from the volunteers also tested positive.
