A test using monoclonal antibodies for detection of antigen in stool samples was compared with culture and histology for noninfected (n = 25), Helicobacter pylori-infected (n = 25), and Helicobacter felis-infected (n = 6) mice. Sensitivity and specificity were 96%. The monoclonal antibody-based test is therefore a noninvasive technique that is able to diagnose H. pylori infection in mice.

INTRODUCTION. Helicobacter pylori infection can be diagnosed by biopsy-based or noninvasive methods. Our aim was to identify H pylori-positive patients on hemodialysis by the noninvasive method of H pylori stool antigen (HPSA) and investigate its diagnostic accuracy for assessment of the eradication of infection after treatment in comparison with urea breath test (UBT). MATERIALS AND METHODS. S...

Twenty-eight of 56 infants in a neonatal intensive care unit had stools positive for adenovirus by the Sure-Vue adenovirus test. Virus cultures of conventionally processed and chloroform-extracted stool samples, as well as conventional and real-time PCR tests, were negative for adenovirus. The cause for the 50% false-positive rate with the antigen test was not determined.

Helicobacter pylori infection is usually acquired in early childhood and it can persist throughout life without antibiotic treatment. This study aimed to compare the accuracy of the noninvasive H. pylori Stool Antigen Test-applied on the stool samples with the invasive gold standart Rapid Urease Test-applied on the gastric biopy samples of patients with upper gastrointestinal complaints. After ...

OBJECTIVE We aimed to diagnose amebiasis and also identify Entamoeba histolytica (E. histolytica) and Entamoeba dispar (E. dispar) in patients with gastrointestinal symptoms in an endemic region in Turkey. METHODS Stool samples obtained from 181 patients with gastrointestinal symptoms from the Harran University Hospital of Sanliurfa were examined for the diagnosis of amebiasis by the three me...

BACKGROUND Acute gastroenteritis stemming from viral causes is very common during the childhood period. Rotavirus and enteric adenovirus are the most common factors of acute gastroenteritis encountered in infants and children. However, the epidemiology of rotavirus and enteric adenovirus gastroenteritis in the east Anatolia region is not well-known. OBJECTIVES We aimed to evaluate the relatio...

BACKGROUND Helicobacter pylori (H. pylori) is one of the most important causes of dyspepsia and gastric cancer and diagnosis can be made by invasive or non-invasive methods. The Atlas Helicobacter pylori antigen test is a new rapid non-invasive method which is simple to conduct. The aim of this study was to determine its sensitivity, specificity, positive predictive value (PPV), negative predic...

background: some antigens of h. pylori are excreted into the stool of infected people. these antigens can be used to detect the infection by immunoassays such as elisa. our aim was to identify these antigens by immunoblotting and affinity chromatography techniques.   methods: four different antigenic preparations, namely, whole cell sonicate (wcs), outer membrane proteins (omps), cytoplasmic an...
