Identification of a novel astrovirus (astrovirus VA1) associated with an outbreak of acute gastroenteritis.
The etiology of a large proportion of gastrointestinal illness is unknown. In this study, random Sanger sequencing and pyrosequencing approaches were used to analyze fecal specimens from a gastroenteritis outbreak of unknown etiology in a child care center. Multiple sequences with limited identity to known astroviruses were identified. Assembly of the sequences and subsequent reverse transcript...
متن کاملAstrovirus-associated gastroenteritis in children.
In a small astrovirus-associated outbreak of gastroenteritis in a ward of a local children's hospital two out of five children with symptoms excreted astrovirus particles. No astrovirus particles were found in faeces from the remaining asymptomatic child, and no other viral or bacterial pathogens were found in any of the children. Virus excretion persisted for only a few days. Rising antibody t...
متن کاملAstrovirus associated gastroenteritis in a children's ward.
During an outbreak of gastroenteritis in a paediatric ward astroviruses were found in faeces from 17 to 27 symptomatic children and from four of 14 members of the staff with diarrhoea. No viruses were found in 10 asymptomatic children. Fourteen of the 21 astrovirus excretors were free of any recognised pathogens, but in the other seven, rotaviruses or pathogenic bacteria were also present. Sero...
متن کاملOutbreak of neonatal gastroenteritis associated with astrovirus serotype 1 at a hospital in Inner Mongolia, China.
This report describes for the first time an outbreak of acute gastroenteritis among neonates associated with human astrovirus (HAstV) serotype 1b at a maternity hospital in Inner Mongolia, China. Of 40 specimens, 28 were astrovirus positive and rotavirus, calicivirus, and adenovirus negative. Poor hygiene likely contributed to the spread and persistence of HAstV in the neonatal care room.
متن کاملPrevalence of Human Astrovirus in Patients with Acute Gastroenteritis
The prevalence of human astroviruses was tested in patients with acute gastroenteritis by using conventional duplex reverse transcription (RT)-PCR and electrophoresis. Diarrheal fecal samples were collected from 9,597 patients at local hospitals in Seoul. The prevalence of astroviruses was 1.0% (94/9,597 patients; mostly infants), and that of sapoviruses was 0.1% (14/9,597 patients). Age- and g...
