The results show that while the diarrhea E. coli ETEC is often present in the drinking water, Helicobacter pylori is not. Other studies have shown that new cases of Helicobacter pylori tend to pop up in connection with various diarrhea illnesses, and this pointed the research team in the right direction.
'We analyzed vomit and diarrhea from cholera patients, and found large amounts of active Helicobacter pylori. We therefore conclude that vomit is a very likely source of new infections'.
