Role of food in environmental transmission of Helicobacter pylori
Helicobacter pylori (H.pylori) is a gram-negative bacterium that has infected more than half of the world's population. This pathogen colonizes the human gastric mucosa and is usually acquired during childhood. It is an important cause of peptic ulcers, chronic gastritis and stomach cancer. Among the risk factors for acquisition of H. pylori infection, poor socioeconomic status, poor sanitizati...

متن کاملTowards a US national estimate of the risk of endemic waterborne disease--sero-epidemiologic studies.
Worldwide literature on serological methods and sero-surveys on waterborne pathogens has been reviewed. Outbreak investigation and research reports have also been examined to aid understanding of the serological response and transmission dynamics. The aim was to seek an estimate of seroprevalence and to determine if this could inform the US national estimate of risk for endemic waterborne infec...
متن کاملFailure to detect Helicobacter pylori DNA in drinking and environmental water in Dhaka, Bangladesh, using highly sensitive real-time PCR assays.
The main transmission pathway of Helicobacter pylori has not been determined, but several reports have described detection of H. pylori DNA in drinking and environmental water, suggesting that H. pylori may be waterborne. To address this possibility, we developed, tested, and optimized two complementary H. pylori-specific real-time PCR assays for quantification of H. pylori DNA in water. The mi...
متن کاملThe association of drinking water quality and sewage disposal with Helicobacter pylori incidence in infants: the potential role of water-borne transmission.
The mode of transmission of Helicobacter pylori, a bacterium causing gastric cancer and peptic ulcer disease, is unknown although waterborne transmission is a likely pathway. This study investigated the hypothesis that access to treated water and a sanitary sewerage system reduces the H. pylori incidence rate, using data from 472 participants in a cohort study that followed children in Juarez, ...
