Background: Enteric viruses, particularly human rotavirus and norovirus, have been shown to replace bacteria and parasites, as the most common pathogens responsible for acute diarrhea. However, there are still few epidemiological data on the simultaneous occurrence of these viruses in Iran. In this regard, the aim of this study was to assess the useful epidemiological data on the gastroenteriti...

background: rotavirus is a major cause of acute diarrhea in children worldwide. it is an important cause of death among young children in developing countries. the aim of this study was to evaluate the prevalence of rotavirus infection in children less than five years old hospitalized for gastroenteritis in jahrom.   methods: one hundred and two stool samples were collected from children less t...

Background: Rotavirus infection is one of the most common gastroenteritis in the world, and a million cases are registered to enter hospital every year. Promyelocytic leukemia proteins (PMLs) are IFN-up-regulated proteins, and one of their critical functions is working as antiviral proteins. Recently, promyelocytic leukemia isoform II (PML-II) has been depicted as an isoform responsible for the...

background: vp4 protein is as spikes on rotavirus outer capsid shell which is responsible for virus attachment to the host. vp4 induces production of neutralizing antibodies which could be used for serotyping of different isolates. methods: simian rotavirus sa11 gene 4 cdna was cloned into a cloning plasmid pdonrtm by recombination reaction using clonase ii enzyme mix. the resulting clone was c...

materials and methods in this descriptive study, 2988 stool samples of patients with acute gastroenteritis were collected from children’s hospitals of 5 main cities of iran. the samples were sent in frozen condition to pediatric infection research center in tehran and stored at -70°c. elisa test was performed for detection of rotavirus antigens. the mean age of study population was 1 to 5 years...

Background: Group A rotavirus (RVA) mainly causes acute gastroenteritis, exclusively in young children in developing countries. The prevalence and determination of the molecular epidemiology of rotavirus genotypes will determine the dominant rotavirus genotypes in the region and will provide a strategy for the development of appropriate vaccines. Methods: A total of 100 fecal samples ...

human rotavirus is a major etiologic agent for infantile diarrhea worldwide. it is responsible for up to 3.3 million deaths per year in children in developing countries. various rapid and sensitive techniques have been developed to readily diagnose rotavirus gastroenteritis. in the present study, we compared the sensitivity and specificity of immunochromatography and rna-polyacrylamide-gel elec...

background and aims: rotaviruses are one of the main causative agents of acute viral gastroenteritis in both young human and animals. several methods have been used for diagnosis of rotavirus infection. most of these methods are not easily available in iran. methods: in our study attempt was made to develop a method which could replace the commercially imported kit. rota virus was purified and ...

Background: Rotavirus is a major cause of morbidity and mortality among children with gastroenteritis. Since the discovery of rotaviruses, several techniques have been used for their laboratory diagnosis; those included Electron Microscopy (EM) and enzyme immunoassay. These methods, however, are expensive and not readily available everywhere. We have developed a technique which can be used for ...

Rotavirus nonstructural glycoprotein NSP4 can induce diarrhea in newborn mice. It has been suggested that NSP4 may be a key determinant for rotavirus pathogenesis and a target for vaccine development. In order to study the biological and morphological role of NSP4 a large amount of the purified protein and antibody against it are required. Simian rotavirus SA11 was propagated in BSCl cell,...
