We report on two children with mild encephalopathy with a reversible splenial lesion associated with group A rotavirus (GARV) infection. We examined stool, serum, and cerebrospinal fluid samples to determine the presence of the GARV VP7 gene and GARV antigen by reverse-transcription PCR and enzyme-linked immunosorbent assay, respectively. GARV antigen was detected in stool samples from both pat...

BACKGROUND AND OBJECTIVES Invasive and non-invasive techniques are used to diagnose H. pylori infection. Some factors influence the choice of a diagnostic test, such as the sensitivity and specificity of the tests, the clinical circumstances and the cost-effectiveness of the testing strategy. The aim of this study was to reveal the relationship between different H. pylori infection diagnosis me...

A survey of hepatitis B patients, asymptomatic hepatitis B antigen (HBsAg) carriers, and control subjects was conducted to determine the relationship between antigenemia and antigen excretion in saliva, urine, and stool. Radioimmunoassay was used to detect HBsAg. Specificity-confirmed HBsAg was detected in the saliva of 6 (30%) of 20 antigenemic patients, 1 (5%) of 20 nonantigenemic patients, 1...

BACKGROUND Noroviruses (NoV) have become one of the most commonly reported causative agents of large outbreaks of non-bacterial acute gastroenteritis worldwide as well as sporadic gastroenteritis in the community. Currently, reverse transcriptase polymerase chain reaction (RT-PCR) assays have been implemented in NoV diagnosis, but improvements that simplify and standardize sample preparation, a...

Background: H. pylori is one of the most important human pathogens, infecting more than 50% of the world’s population. While over 80% of infected individuals are asymptomatic, it can lead to intestinal and extra-intestinal manifestations. Intestinal manifestations include peptic ulcer disease and some gastrointestinal malignancies. Aims of the study: We aimed in this study to determine the prev...

development of a stool antigen immunoassay to detect helicobacter pylori infection requires monoclonal antibody against the specific antigen. alkylhydroperoxide reductase (ahpc) of helicobacter pylori has been described as a specific and unique enzyme for h. pylori and therefore, both h. pylori ahpc and anti-ahpc could be useful in the development of serologic and stool antigen tests, for detec...

Objective: SARS-CoV-2 RNA positivity in stool COVID-19 infection has been reported at rates varying between 6-83%. The purpose of this study was to determine the prevalence H.pylori and investigate whether it determines disease prognosis patients.
 Methods: This conducted on 117 confirmed patients who were hospitalized due symptomatic pneumonia tested for antigen. Stool H. pylori test outc...

A new rapid lateral flow fecal antigen detection test for Cryptosporidium was evaluated using diarrheal stool samples from a cohort of children in Bangladesh. The test had a sensitivity of 100% and a specificity of 94% when compared with enzyme-linked immunosorbent assay antigen detection.
