| BACKGROUND: Acute gastroenteritis (AGE) is a common disorder that affects children worldwide. It is usually caused by viral agents, including rotavirus, enteric adenovirus, norovirus, and astrovirus groups. Currently, there are few reports about co-infection among these viruses, mainly in Brazil. METHODS: This is a retrospective study in which 84 rotavirus-positive samples from hospitalized patients at a teaching hospital in Southern Brazil, collected in the 2001-2010 period, were analyzed by polymerase chain reaction (PCR) and reverse transcription - polymerase chain reaction (RT-PCR), for the investigation of enteric adenovirus, astrovirus, and norovirus. RESULTS: In total, 12 of the 84 (14%) samples were positive to enteric adenovirus or norovirus.... |

| Acute gastroenteritis caused by viruses is one of the leading causes of infantile morbidity. The aim of the present study was to investigate the presence of human caliciviruses of the genera norovirus and sapovirus in children up to 3 years of age with acute gastroenteritis from low-income communities in the city of Salvador, Brazil. This study is an extension of previous work carried out to establish the profile of the most prevalent enteric pathogens present in these communities. In this report, 139 fecal samples, collected from July 2001 to January 2002 were analyzed by RT-PCR and 13 (9%) were positive for human caliciviruses. By sequencing, seven isolates were characterized as norovirus genogroup GII and one as sapovirus genotype GII/1. Sequencing of... |
