By far the most common infection in the world is caused by the organism helicobacter pylori. It is estimated that every second person was currently or in the past infected with this bacteria, and most of us came into contact with it as children.
This specific bacteria was identified 35 years ago as one of the causes of gastritis and ulcer disease. The importance of learning about the bacterium was confirmed in 2005 by the Nobel Prize and the growing interest of a large number of scientists in this problem.
Further research has confirmed that this organism is a sure cause of cancer. Helicobacter pylori can be an insidious tenant in the gastrointestinal tract twenty years before it leads to a tumor. To make the paradox bigger – the treatment of this infection lasts for two weeks.
