Background Helicobacter pylori antibody titters fall very slowly even after successful treatment. Therefore, tests detecting H. pylori antibody lack specificity and sensitivity. On the other hand, H. pylori stool antigen tests are reported as an alternative assay because of their reliability and simplicity. However, the comparative performance of H. pylori stool antigen tests for detecting the ...

We evaluated the Meridian IC-STAT direct fecal and broth culture antigen detection methods with samples from children infected with Escherichia coli O157:H7 and correlated the antigen detection results with the culture results. Stools of 16 children who had recently had stool cultures positive for this pathogen (population A) and 102 children with diarrhea of unknown cause (population B) were t...

BACKGROUND Helicobacter pylori (Hp) infection is mainly acquired during childhood; it is recognised as a cause of gastritis and peptic ulcer and it has been classified as a group A carcinogen by World Health Organization. The exact mode of transmission is as yet, not known. Aim of our study has been to identify risk factors associated with Helicobacter pylori infection in a preschool and school...

shigellosis is an important public health problem, especially in developing countries. antibiotic treatment of bacterial dysentery, aimed at resolving diarrhea or reducing its duration is especially indicated whenever malnutrition is present. first-line drugs include ampicillin and trimethoprim sulfamethoxazole(tmp-smx); however multidrug-resistance has occurred and careful antibiotic selection...

The aim of this study in Iraq was to determine the sensitivity and specificity of a commercial ELISA test for detection of Giardia lamblia antigen in stool. Of 84 stool samples from children in Duhok governorate, 42 were positive and 42 negative for G. lamblia or other parasites by direct and indirect microscopic examination. The sensitivity of the ELISA test for detection of G. lamblia versus ...

Rotavirus is a major cause of severe acute gastroenteritis in infants and young children worldwide. It responsible for 40% childhood hospitalization. has been estimated that about 23% diarrhoeal death occurs due to the rotavirus infection India. To study epidemiology less than 5 years age at tertiary care teaching hospital. A total 240 stool samples were collected from <5 suffering diarrhea ...

Viral pathogens are the most common cause of gastroenteritis in developed countries. Human rotavirus and adenovirus infections are major causes of acute outbreaks and sporadic cases of gastroenteritis, occurring primarily among children less than 2 years of age. Patient hospitalization is often required, with enormous infection control implications. This work describes the development of real-t...

An antigen-capture enzyme-linked immunosorbent assay employing rabbit and mouse antisera to Giardia lamblia cyst antigens was developed for the diagnosis of Giardia infection through detection of G. lamblia-specific stool antigens in cell-free aqueous eluates of human stool. This is the first report of the use of anti-cyst antibodies in an enzyme immunoassay for G. lamblia. The assay gave a pos...
