Helicobacter pylori infection is now the most common infections in the world. It is estimated that half of the world population is infected with this bacterium. However, there are large geographic, age and economic differences between developed countries and developing countries in the incidence cancer de boca of infection. Genetic predisposition also affects how the incidence of, and the prevalence of infection. The infection occurs very early in childhood. After more than a decade of study, today we can say that Helicobacter pylori infection has mostly epidemiological characteristics of bacterial cancer de boca infections of the time: the highest incidence in the preschool age, grouped cancer de boca by individual families, depending on the number of members, cancer de boca the greater infectivity.Therefore in terms of lower socio-economic standards and level of education. The increase in infestation in childhood moving between 20 and 80% for each year of age, while in adults, any age over, carries 1-3% higher incidence. Socio-economic conditions and living conditions significantly affect the incidence of infection. In the developed countries the incidence of infection is growing by about 3% with each decade of life. The prevalence of infection in developing countries cancer de boca is very high at around 80% of the adult population, in contrast to developed countries where the percentage is much lower and is around 40%. By comparison, in Europe the prevalence of Helicobacter pylori infection in patients sixty years of age is the same as in the twenties in developing countries.
Where we are located? On examination gastrobioptičkih samples from gastric antrum of 1317 respondents, Helicobacter cancer de boca pylori infection was histologically found in about 60%, which puts us between the developed and the developing world. Similar cancer de boca results were obtained by serological and histological methods of diagnosis by other authors in the country.
Helicobacter pylori is a gram-negative cancer de boca bacterium with five unipolar flagella. This form allows the bacteria to pass through mucus, which is located above the epithelial cells of the gastric environment of the human stomach that this microorganism redone. In addition to the gastric cancer de boca epithelium, the bacteria can be found on the metaplastic gastric epithelium, usually in the duodenal cancer de boca bulb, but also in the esophagus, Meckel cancer de boca 's diverticulum and rectum. This bacterium is also but less frequently, can be found on Bare epithelium in the esophagus. Various bacteria from this genus are found in different animals but Helicobacter pylori can be found only in the human stomach and rarely in other primates or domestic životinja.ogija cancer de boca
Helicobacter pylori is remarkably adapted to life in the human stomach. The basis for survival in the middle where other microorganisms can not survive, is to create an enzyme urease that decomposition of urea in the stomach produces ammonia and carbon dioxide, where his alkalnošću ammonia protects the bacteria from the effects of acidic gastric juice. Another significant feature is the presence of different antigens on the surface of the bacteria, which were more telling in the following chapters.
Reservoir of infection is human stomach. In some farm animals can be found in the stomach Helicobacter cancer de boca pylori, such as cats and dogs. Once again we note that the infection is far more common among workers in the meat industry than in others, because it is connected on one side to their low socio-economic status, or being infected with animals that are processed cancer de boca immediately after slaughter. In developed countries, drinking water comes from water purified and disinfected, as compared to developing countries where the water supply without control. Drinking water in developing countries from uncontrolled sources cancer de boca of supply plays an important role in feko-oral transmission of disease. There is considerable evidence that Helicobacter pylori infection can be transmitted through drinking water. It has been shown that H. pylori survives to 3 days in water. Apart from drinking contaminated water, Helicobacter pylori infection can be transmitted, cancer de boca and fruits and vegetables Pran infected cancer de boca water. This method of transmitting infection is found in some parts of Chile, cancer de boca where the incidence is significantly higher in people who do not cook fruits and vegetables previously washed with infected water, compared to a population that cooked fruits and vegetables.
In developed countries, water is an important way of transmitting the infection. A study in Germany has shown that there is no significance in the prevalence of the disease in relation to the manner of supplying drinking water. Helicobacter pylori infection can also be transmitted during gastroenterological examination of the upper gastrointestinal tract during endoscopy or intubacionih functional tests. Hygiene and cleaning of instruments between the two interventions significantly reduces riz
