Rotavirus (RV) belongs to the Reoviridae virus family and virion comprises of three concentric protein layers. Worldwide, rotavirus is most common cause severe gastroenteritis (G.E.) among infants young children especially in those countries which has not launched a RV vaccination program approximately 40% hospitalized patients suffering from were infected with RV.

Background: Rotavirus infection is the most important cause of infectious, severe and dehydrating diarrhea death in children aged 5 under continues to have a significant impact on child morbidity mortality our countries. The aim this study was retrospectively determine prevalence rotavirus adenovirus patients presenting with gastroenteritis symptoms distribution pathogens according gender, age ...

Background: Human rotavirus (HRV) is the causative agent of severe gastroenteritis in children and responsible for two million hospitalizations and more than a half-million deaths annually. Sequence characteristics of the gene segments encoding the VP7 and VP4 proteins are used for the genotype classification of rotavirus. A wide variety of molecular methods are available, mainly based on rever...

BACKGROUND Rotavirus is the most common cause of severe diarrhea in infants. The economic costs of treating severe rotavirus can be quite significant and are important to include in any evaluation of prevention programs. The aim of this study was to determine utilization of health care resources and costs incurred due to severe diarrhea associated with rotavirus infection in Mexican children < ...

OBJECTIVE Data show that after the implementation of routine rotavirus vaccination for infants in the United States, community-acquired (CA) rotavirus cases declined substantially in the 2007-2008 season. The impact of community-based rotavirus vaccination on the substantial burden of hospital-acquired (HA) rotavirus has not been documented. PATIENTS AND METHODS We assessed CA and HA rotaviru...

Rotavirus circulates extraintestinally in animals used as models for rotavirus infection and in children. Rotavirus infection in mice was used to define host or viral factors that affect rotavirus viremia. Antigenemia was observed with homologous and heterologous rotaviruses, and neither age nor mouse strain genetics altered the occurrence of rotavirus antigenemia or viremia. Rotavirus RNA and ...

We compared a new, rapid, qualitative test for rotavirus (TestPack Rotavirus; Abbott Laboratories, North Chicago, Ill.) with another enzyme immunoassay (Pathfinder Rotavirus; Kallestad Laboratories, Inc., Austin, Tex.) and electron microscopy to determine its clinical utility in a population of symptomatic hospitalized children. In the first part of the study, 100 frozen stool samples were test...

BACKGROUND Pediatric vaccination has resulted in declines in disease in unvaccinated individuals through decreasing pathogen circulation in the community. About 2 years after implementation of pediatric rotavirus vaccination in the United States, dramatic declines in rotavirus disease were observed in both vaccinated and unvaccinated children. Whether this protection extends to adults is unknow...

Monoclonal antibodies directed against two rotavirus surface proteins (vp3 and vp7) as well as a rotavirus inner capsid protein (vp6) were tested for their ability to protect suckling mice against virulent rotavirus challenge. Monoclonal antibodies to two distinct epitopes of vp7 of simian rotavirus strain RRV neutralized RRV in vitro and passively protected suckling mice against RRV challenge....

The effect of circulating passive antibody on immunity to bovine rotavirus infections in neonatal calves was investigated. In the first experiment, rotavirus antibody titers in the small intestinal lumina of 5- and 10-day-old calves with a wide range of serum rotavirus antibody titers were determined. Neutralizing antibody was present in the small intestinal lumina in titers that correlated wit...
