This is all the medical information about the bacteria and what doctors are doing to fight the bacteria. I have also found some cures for gastric ulcers, gastritis, and duodenal ulcers, and how it is a risk factor for causing gastric cancer and non-Hodgkins lymphomas in the stomach. This shows how it acts as a pathogen, which is tied in with our bodies immune response. Then a brief look at treatments for the infection of H. pylori and how certain drugs are becoming resistant. There are also some of the possible ways in which medical technology and microbiology are coming together to develop new drugs and the possiblity of a vaccine against H. pylori and also some of the preventive measures that can be taken to reduce the chances of getting the disease.
Epidemiology is the study of the factors that cause a disease to be present or absent.
According to the Center for Disease Control, there is no concrete evidence as to the spread of H. pylori between person to person. They believe that it is through oral to oral contamination, and fecal to oral contamination. It is believed that some water sources are contaminated with the bacteria, and poor methods of cleaning the water can lead to infection. The Helicobacteria Foundation believes that the most common method of transfer of the bacteria between people is from fecal to oral routes. This is believed because it is possible for microbiologists to grow cultures of H. pylori using a stool sample.
