Background: Helicobacter pylori (H. pylori) is considered as one of the most prevalent gastric infections which cause chronic gastritis and predispose to cancer stomach. So, diagnosis and eradication should be rapid to decrease the risk of gastric cancer. Aim of the study: To evaluate the role of rapid urease test (RUT) and faecal antigen test (FAT) added to serological test for rapid diagnosis...
BACKGROUND Well-devised studies comparing new but different monoclonal fecal tests for diagnosing Helicobacter pylori infection are scarce. The objective of this study was to compare the diagnostic accuracy of 3 monoclonal stool tests: 2 rapid in-office tools-RAPID Hp StAR and ImmunoCard STAT! HpSA-and an enzyme immunoassay test-Amplified IDEIA Hp StAR-for diagnosing H. pylori infection prior t...
The Leifson staining method was used to diagnose Helicobacter pylori infection and was compared to histology, culture, and the rapid urease test (RUT). Histology gave the best sensitivity (98%), compared to Leifson staining (97%), culture (92%), and RUT (85%) (P < 0.005). Leifson staining is a sensitive, rapid, economical method for diagnosis of H. pylori infection in dyspeptic patients.
The presence of C pylori infection was determined in 1445 patients undergoing upper gastrointestinal endoscopy over a 12 month period. The presence of C pylori was detected in gastric mucosal biopsy specimens by the biopsy urease test, microscopy (Gram stained smears and histology) and culture. Two media were used for the biopsy urease test: Christensen's urea broth (for the first 600 patients)...
A total of 140 mycobacterial isolates from patients treated at Fitzsimons Army Medical Center or the National Jewish Hospital and Research Center and from animal specimens submitted to the National Veterinary Services Laboratory were tested by using a urease procedure modified for use with a BACTEC model 301. Mycobacterial suspensions were prepared by using Middlebrook 7H10 Tween broth. Of the ...
Objective: The purpose of this study is to compare the diagnostic performance rapid urease test for H. pylori in endoscopic samples gastric juice compared with same mucosa. Materials and methods: Cross-sectional, comparative prospective concordance tests, carried out patients referred a medical center Bogotá DC, Colombia an esophagogastroduodenoscopy. We included 130 older than 18 years,...
In this paper, we evaluated the anti-Helicobacter pylori activity and the possible inhibitory effect on its associated urease by Palmatine (Pal) from Coptis chinensis, and explored the potential underlying mechanism. Results indicated that Pal exerted inhibitory effect on four tested H. pylori strains (ATCC 43504, NCTC 26695, SS1 and ICDC 111001) by the agar dilution test with minimum inhibitor...
Helicobacter pylori (H.Pylori) is the most common human infection in the world. This agent has a strong role in pathogenesis of chronic gastritis and peptic ulcer. Therefore introducing of simple and cost effective tests are important for diagnosis of H.Pylori infections. ELISA has been considered as an alternative test compare with biopsy, histological staining, culture and urease test in diag...
Helicobacter pylori (Hp) were detected in the dental plaque in 40 patients with peptic ulcer, chronic gastritis or gastric cancer with rapid urease test, anti-Hp fluorescein-labelled antibody staining, bacterial culture and electronic microscopy. At the same time, biopsy specimens from the gastric antrum of these patients were studied with WS staining and rapid urease test to detect Hp. The res...
