This study examines the use of fecal indicator bacteria (FIB) as a predictor of the presence of Helicobacter spp. A combination of standard culture and molecular techniques were used to detect and quantify FIB, Helicobacter spp. and H. pylori from five North American rivers of different size and with different land use characteristics. Primers designed to amplify genes specific to Helicobacter ...

BACKGROUND Hepatitis C virus (HCV) is considered the most common etiology of chronic liver disease in Egypt, which may progress to cirrhosis and hepatocellular carcinoma (HCC). Previous studies have documented an association between Helicobacter pylori (H. pylori) infection and liver cirrhosis with or without HCC. This study aimed to investigate the presence of H. pylori DNA in the liver tissue...

conclusions: vegetables are a new source of h. pylori and accurate washing of vegetables improves such contaminations. results: the results showed that 44 of 460 samples (9.56%) were positive for h. pylori using the culture method. the polymerase chain reaction technique showed that 50 of 460 samples (10.86%) were positive for h. pylori. un-washed leek, traditional salad, un-washed basil and un...

Helicobacter pylori (H. pylori) is a common gastrointestinal bacterial strain closely associated with the incidence of chronic gastritis, peptic ulcers, gastric mucosa-associated lymphoid tissue lymphoma, and gastric cancer. A current research and clinical challenge is the increased rate of antibiotic resistance in H. pylori, which has led to a decreased H. pylori eradication rate. In this arti...

Aim: A reliable diagnosis of Helicobacter pylori (H. pylori) is important in clinical practice and research. The aim this study was to compare the sensitivity specificity Giemsa stain with hematoxylin eosin (H&E), Toluidine blue, Gimenez Warthin-Starry detection gastric biopsy also immunohistochemistry (IHC) H. organism biopsy. Method: retrospective cross-sectional included 200 formalin-fix...

Objective(s):Helicobacter pylori infection occurs worldwide, but the prevalence of this infection varies greatly among different countries and population groups. The aim of this study was to determine the seroprevalence of anti-Helicobacter pylori and anti-cytotoxin-associated gene A (CagA) antibodies in asymptomatic healthy population in the center of Iran and to investigate the relation with ...

BACKGROUND Over the past few years, the profile of Helicobacter pylori infection has changed in Japan. In particular, the relationship between H. pylori and gastric cancer has been demonstrated more clearly. Accordingly, the committee of the Japanese Society for Helicobacter Research has revised the guidelines for diagnosis and treatment of H. pylori infection in Japan. MATERIALS AND METHODS ...

BACKGROUND In the USA, atrophic gastritis and gastric cancer are rare, whereas gastro-oesophageal reflux disease (GERD) is common. Infection with Helicobacter pylori, especially a CagA positive strain, is unusual in patients with GERD/Barrett's oesophagus in the USA. AIM To examine the relation between Barrett's oesophagus and CagA positive H pylori in Colombia, a country with a high prevalen...

Background: Helicobacter pylori (H. pylori), is a common infection in pregnant women accompanied by variations in the levels of the IgM, IgA and IgG antibody isotypes. The variations of anti-H. pylori antibodies during and after pregnancy, and the extent of protection they provide to the mother and the fetus are not completely understood. Objectives: To investigate the changes of the anti-H. py...
