We developed a buffered azide-free urea medium which is sensitive, specific, and nontoxic for rapid detection of Campylobacter pylori in gastric biopsies. Detection of urease produced by the organism provides the basis for the test. The substrate is urea in monobasic sodium phosphate buffer, and phenol red provides indication of the pH change that results from urease activity. A rapid change fr...

BACKGROUND Rapid urease tests for Helicobacter pylori have a sensitivity of 80% to 90%. Therefore histologic examination of gastric biopsies is recommended as a "backup" diagnostic test in rapid urease test-negative patients. However, noninvasive tests (urea breath test, serology, whole blood antibody tests) may provide a more rapid diagnosis and be less expensive but offer similar accuracy. ...

Gastric biopsy specimens from 283 patients with ulcer and non-ulcer dyspepsia attending five gastroenterology clinics in the northern region of the United Arab Emirates (UAE) were tested by the agar gel test (n = 115) or the ultra-rapid endoscopy room test (n = 168) for the presence of Helicobacter pylori urease. Results were compared with a histological technique using the Romanowsky type (Dif...

OBJECTIVE To analyze the epidemiological profile of patients with gastroduodenal ulcer perforation and verify if the presence of H. pylori in the peritoneal and intraluminal secretions of these patients can be assessed by rapid urease test. METHODS We conducted a prospective, descriptive, cross-sectional study with data from patients in a hospital at a regional level, in patients with peptic ...

Seventy-five consecutive patients referred for upper gastrointestinal tract endoscopy were evaluated for Campylobacter pylori infection by pathology, culture, and a biochemical test to detect bacterial urease. Forty-eight patients (64%) had C. pylori present based on pathology or culture or both. Thirty-two urease tests were positive after 1 h, all in patients with C. pylori detected by the two...

INTRODUCTION The endoscopic diagnosis of Helicobacter pylori infection in patients with bleeding peptic ulcer is limited by a decreased sensitivity in standard invasive tests, rapid urease test and histology. There is controversy about the convenience of using one, neither, or both diagnostic tests. AIMS To evaluate the results of simultaneously performed rapid urease test and histology in th...

o bjectives: gastric infection with helicobacter pylori may be one of the main causes of halitosis. this study was performed to evaluate the relationship of heli- cobacter pylori infection with halitosis. materials and methods : this case control study was performed on 44 dyspeptic patients with a mean age of 34.29±13.71 years (range 17 to 76 years). the case group included 22 patients with hal...

Flexible pavements comprise about 93 percent of paved roads in the United States. Although flexible pavements are widely used for reasons such as cost, constructability and consistent performance, they are often subject to severe rutting. Rutting is the accumulation of longitudinal depressions under the wheelpaths caused by the repeated traffic loads. Rut is a major concern for the integrity of...

this study was performed to detect cultivable canine gastric helicobacter-like organisms (ghlo’s) and to evaluate their sensitivity to common antibiotics in two groups of naturally infected dogs (pets and stray dogs). gastric samples were taken from the body and antrum of 30 pets and 30 stray dogs. from each part of canine gastric mucosa, four gastroscopic samples were used for impression smear...

Background: Helicobacter pylori (H. pylori) infection has become a remarkable worldwide health problem. The eradication of H. challenge. Probiotics have proven beneficial in reducing the side effects and increases patient compliance. Lactobacillus reuteri (L. reuteri) is frequently used probiotic considered safe for human consumption. aim this study was to compare effectiveness conventional ant...
