To clarify the infectious etiology of acute gastroenteritis in children less than 5 years of age, we conducted a 1-year prospective case-control study. Stools from150 children with diarrhea and 150 age-matched controls admitted in the hospital for illness involving system other than that of gastrointestinal tract were examined, and their parents were interviewed regarding concerning symptoms. S...

Human astroviruses are a major cause of pediatric gastroenteritis, especially in immunocompromised children. We conducted a retrospective study to demonstrate that diverse astrovirus genotypes can co-circulate in pediatric oncology patients. A subset of cases is associated with long-term virus shedding (range 17-183 days).

Aim: The present study aimed to detect Human bocavirus (HBoV) in stool samples from young children below 5 years complaining of acute gastroenteritis (GE) addition detection rotavirus, norovirus, and astrovirus. Methods: included 90 with GE excluded bacterial pathogens. determination the presence HBoV was performed by nested polymerase chain reaction (PCR) beside astrovirus norovirus multiplex ...

The purpose of this study was to characterize astrovirus in faecal samples collected from children with and without diarrhea in São Paulo, Brazil, grouped into two sets: EPM and HU. Detection and genotyping were carried out using reverse transcription nested polymerase chain reaction (RT-PCR) with specific primers directed towards the genome open reading frame 2 (ORF2). Results for EPM set show...

Only two complete genome sequences of MLB2 astroviruses are available, one from an Indian child with diarrhea and another from plasma of an American child. Here we report the complete MLB2 genome sequence from a Turkish child with diarrhea. This MLB2 astrovirus genome sequence shows high nucleotide identity with the American MLB2.

Although a relatively recently emerged virus, identified only in 2004 as a separate species of avian astrovirus, chicken astrovirus (CAstV) has been associated with poor growth of broiler flocks, enteritis and diarrhea and is a candidate pathogen in cases of runting stunting syndrome. More recently CAstV has been implicated in cases of two other diseases of broilers as the sole etiological agen...

Out of 1,588 faecal samples of children taken from three locations of the Central West Region of Brazil, 57 were positive for astroviruses (HAstVs) using reverse transcription-polymerase chain reaction (RT-PCR). They were genotyped by nested RT-PCR and/or genomic sequencing. HAstV-1 (42.8%), HAstV-2 (23.2%), HAstV-3 (3.6%), HAstV-4 (14.3%) and HAstVs -5, -6, -7 and -8 (1.8% each) were detected....
