How does Helicobacter pylori come from

summary

We often have physical examination on our body, because only physical examination can we know if there is any problem in our body. Of course, we often see Helicobacter pylori in the report. Let's popularize the science about how Helicobacter pylori came.

How does Helicobacter pylori come from

Helicobacter pylori is one of the most critical conditions for its growth. In 1983, it was first successfully isolated from gastric mucosa biopsy of patients with chronic active gastritis. It is the only microbial species that can survive in human stomach. Helicobacter pylori includes gastritis, peptic ulcer and lymphoproliferative gastric lymphoma caused by Helicobacter pylori infection. The poor prognosis of Helicobacter pylori is gastric cancer.

Second, it is generally believed that the clinical process of Helicobacter pylori infection is as follows: Helicobacter pylori colonizes and infects the gastric mucosa through mouth, causes chronic and superficial gastritis after several weeks or months, develops into duodenal ulcer, gastric ulcer, lymphoproliferative gastric lymphoma, chronic atrophic gastritis after several years or decades, and the latter is the most dangerous factor leading to gastric cancer . Experts believe that Helicobacter pylori infection increases the risk of gastric cancer by 2.7-12 times. If there is no Helicobacter pylori infection, at least 35% - 89% of gastric cancer will not occur.

Third: Helicobacter pylori disease is acquired, which has been the consensus of scholars all over the world. The mode of transmission is not very clear, but the most likely route is mouth to mouth and fecal to mouth transmission. The following experiments have proved that: 1. Helicobacter pylori DNA is detected from saliva, dental plaque and feces of patients by PCR; 2. Helicobacter pylori is isolated from dental plaque and feces; 3. The same Helicobacter pylori strain is isolated from the feces of multiple members of the same family.

matters needing attention

In fact, Helicobacter pylori is not too big a problem, if it is positive, then it does not need radical cure, the harm to the human body will not be great, you can take antibiotics to alleviate the bacteria.
