Rotavirus, the most common cause of severe gastroenteritis in early childhood, is now a vaccine preventable disease with immunisation added to the Australian publicly funded schedule in July 2007. To better understand rotavirus epidemiology in Queensland prior to vaccine introduction, we used 3 routinely-collected data sources. We analysed hospital records of all children less than 5 years of a...

Rotavirus is a major etiologic agent of gastroenteritis in infants and young children worldwide, and also in variety of mammals and birds. The most prevalent species of rotavirus, i.e., group A rotavirus is highly diverse antigenically and genetically. Two major outer capsid proteins of rotavirus, VP7 and VP4, contain neutralization antigens. Based on the antigenicities and gene sequence divers...

Rotavirus-positive specimens were recovered from 143 Afrikander calves on two farms in the northeastern Cape of South Africa during late 1988 and 1989. The rotavirus strains were analyzed by polyacrylamide gel electrophoresis of the RNA genome, and four rotavirus RNA electrophoretypes, each with a long profile, were identified. A distinct RNA profile was identified on the farms during 1988, but...

Rapid detection of group A rotavirus was performed by using ImmunoCardStat! Rotavirus (ICS-RV) (which uses immunogold-based, horizontal-flow membrane technology), two commercial enzyme immunoassays (Premier Rotaclone and TestPack Rotavirus), and electron microscopy. A total of 249 stool specimens collected from children with gastroenteritis between February and April 1997 were tested. After res...

Group A rotaviruses are major pathogens causing acute gastroenteritis in children and animals. To determine if group A rotavirus replicates and induces disease in rats, antibody-negative Lewis neonatal or adult rats were inoculated orally with tissue culture-adapted human (Wa, WI61, and HAL1166), simian (rhesus rotavirus [RRV] and SA11), bovine (WC3), lapine (ALA), or porcine (OSU) rotavirus st...

INTRODUCTION Rotavirus (RV) infection is the most common cause of gastroenteritis in children. This paper identifies the most common genotypes of rotaviruses isolated from children hospitalized with gastroenteritis and attempts to determine any relationship between infection with a certain rotavirus genotype. MATERIAL AND METHODS The investigated group consisted of 68 consecutive children wit...

A 1:1 matched case-control study of calves under 1 month of age was carried out by weekly visits to 7 dairy farms in Mashhad from May 2008 to October 2008. Fecal samples were collected from a total of 112 calves with clinical signs of diarrhea and from 112 matched animals without clinical signs of diarrhea as assessed by a scoring system. The samples were investigated for the presence of Rotavi...
