Did you know that the bacteria that causes ulcers was discovered by accident? In 1982, two Australian doctors, Barry Marshall and Robin Warren, tried to cultivate the bacteria, but it proved extremely difficult. When they wanted to grow the bacteria, they only waited the usual two days for each experiment. One day they accidentally left petri dishes in the laboratory and went on Easter vacation. After five days, upon their return, colony growth on the Petri dishes was noted. They were the first scientists able to cultivate the bacteria. Later, these bacteria were named Helicobacter pylori. This discovery helped to understand ulcers. Marshall and Warren received the 2005 Nobel Prize for their discovery of H. pylori. These bacteria are widespread throughout the world. More than 50% of the world's population is infected with H. pylori; although not everyone infected with H. pylori suffers its symptoms. Because of its high prevalence, researchers are studying its spread to try to determine how we become infected. About 30 years after the discovery of H. pylori, different researchers put forward different hypotheses about the mechanism of spread of H. pylori. By examining the different hypotheses proposed on the mechanisms of propagation, it becomes clear that they are linked to culturally specific habits due to the biological mechanisms of propagation. This suggests that effective prevention will involve different public awareness mechanisms and educational campaigns that challenge cultural beliefs, values ​​and practices. Since the transmission route of H. pylori infection is not yet clear, researchers put forward different theories about the mechanism of spread of H. pylori. .pylori. Over the past thirty years, researchers have hypothesized countless ways to combat bacteria...... middle of article ......ion, researchers in the field are studying other drugs to find one more effective in eradicating the disease. However, given that the disease is spread through cultural habits and practices, any effort to eradicate it will need to involve public awareness and education campaigns that challenge cultural beliefs, values ​​and practices. . The best solution to reduce prevalence is to prevent H. pylori infection. Developing vaccines to prevent and control H. pylori would be very effective, but since researchers are still working on making vaccines and have not yet developed an effective one, we need to find other ways and strategies to reduce and control the spread. The most effective way at present is to educate the public through educational campaigns on how to help control the spread of H. pylori by changing certain cultural habits and practices..
