   Recently, researchers from Boston University, Harvard Medical School and the Massachusetts Institute of Technology announced a new discovery that would change the conventional way people understanding the form of bacteria invading the body.



   Studies have shown that Helicobacter pylori causing gastric ulcer in humans has an intelligent biochemical strategy that can survive, mobilize and further invade the host organism by altering the physical properties of the surrounding environment.
   The latest issue of "Proceedings of the National Academy of Sciences," published this discovery. Helicobacter pylori are bacterium that can invade multiple parts of the stomach and cause chronic inflammation of the stomach. It is also closely related to gastric ulcer and gastric cancer. This bacterium can survive at extremely high acid environment that other bacteria cannot tolerate. This is because it produces ammonia to neutralize stomach acid. At the same time, the study also shows that it can also transform the surrounding environment and thus move freely.
   Under the microscope, the researchers observed that if the mucus in the gastric juice is liquid, the bacteria can freely enter in and leave out. And if the mucus is mucilaginous glue, bacteria cannot make invasion. A more subtle microscopic imaging technique shows that changes in pH are d
   "The medical community had always believed that Helicobacter pylori with a helical profile could penetrate the body's gummy mucus layer like a screw into a cork, but recent studies have shown that this is not the case: they employ an intelligent biochemical strategy to invade the host". The researchers hope this finding can further promote the study on prevention of Helicobacter pylori infection. At the same time, the research can provide new therapies for fighting bacterial infections in the related field.
