Importance of the fiberoptic endoscope cleaning procedure for detection of Helicobacter pylori in gastric biopsy specimens by PCR.

PCR and RFLP Analysis for Identification and Typing of Helicobacter pylori Strains from Gastric Biopsy Specimens

Compression of Histopathology, Culture and Rapid Urease Test in Diagnosis of Helicobacter Pylori in Gastric Biopsy Specimens

Abstract Background and Objective: Helicobacter pylori (H. Pylori) infection is related to chronic gastritis, peptic ulcer, duodenal ulcer and gastric cancer. Thus, identification and treatment of the infection have a considerable importance. The aim of this study was to compare three methods of Histopathology, Culture and Rapid Urease test (RUT) in identification of H. Pylori in gastric bio...

Detection of Helicobacter pylori from Gastric Biopsy Samples by Culture, Polymerase Chain Reaction and Histopathological Methods in Eastern Turkey

The aims of this study were to detect Helicobacter pylori (H. pylori) by culture, polymerase chain reaction (PCR) and histopathological methods, to determine the prevalence of active H. pylori infection in Elazig Province, East of Turkey and to evaluate the relationship between H. pylori infection and sex. Antrum and corpus samples of 184 Turkish patients (85 male and 99 female, age range 17 to...

TLR4 and TLR2 Expression in Biopsy Specimens from Antral and Corporal Stomach Zones in Helicobacter pylori Infections

Background: It is not yet known which types of Toll-like receptors (TLRs) are most effective in Helicobacter pylori (H. pylori) recognition. It is also not known which gastric zones have the most prominent roles in TLR-mediated bacterial recognition. The aim of this work was to analyze the expression of TLR2 and TLR4 in biopsy specimens from H. pylori-infected patients. Methods: Thirty-eight...

Nested polymerase chain reaction for detection of Helicobacter pylori in gastric biopsy specimens.

Sensitivity and specificity are important for tests used to defect Helicobacter pylori infection from gastric biopsy specimens. Molecular methods, such as PCR and nested PCR, are sensitive methods for H. pylori detection. The objective of this study was to evaluate the performance of PCR and nested PCR compared to culture, the rapid urease test (RUT) and histology for the diagnosis of H. pylori...
