| Abstract | Helicobacter pylori is a Gram negative mobile bacillus. Its morphology is spiral and is considered catalase, oxidase and urease positive. It is a bacterium of worldwide distribution whose prevalence varies according to geographical distribution, ethnicity, race, socioeconomic factors, hygiene and sanitation. There are several distribution routes but the best known are oral-oral, gastrooral and fecal-oral; it has also been described that the bacteria can be transmitted through food, animals and water. For the realization of the following review article, a search was made in the databases PubMed, PubMed Central and Science Direct using the terms Helicobacter pylori, water, detection methods, VBNC y cocoid form. Obtaining as a result that there is a high prevalence of this bacterium in developing countries that have poor sanitation conditions, so that water becomes one of the channels through which the bacteria travels, stays alive, arrives to the stomach of the human being and colonizes it. H. pylori survives in water thanks to several mechanisms such as its change to coccoid form (VBNC), its ability to form biofilms and to associate with free-living amoebas. Due to its presence in a viable but not cultivable way, it is difficult to detect in water samples, so it is necessary to use molecular methods such as PCR, FISH and LAMP, however, these techniques must be improved in order to detect the viability of the cells to be 100% effective methods, which will benefit public health. |
