1. First report of human astrovirus MLB2 in Brazil detected in feces of children with acute gastroenteritis living in the state of Roraima, Northern Brazil
ABSTRACT Human astrovirus (HAstV) 1-8 and highly divergent HAstVMLB1−3 genotypes have been detected in children both with and without acute gastroenteritis (AGE). One hundred and seventy fecal samples from children (≤5 years old) living in the Amazon region were evaluated for the presence of HAstV1-8, HAstV MLB1−3 and HAstVVA1−3, using an usual RT-PC

2. Detection and genetic characterization of Mamastrovirus 5 from Brazilian dogs
Abstract Mamastrovirus 5 (MAstV5), belonging to the Astroviridae (AstV) family, previously known as canine astrovirus or astrovirus-like particles, has been reported in several countries to be associated with viral enteric disease in dogs since the 1980s. Astroviruses have been detected in fecal samples from a wide variety of mammals and birds that are assoc

3. Detecção de vírus entéricos em pâncreas e baço de frangos com a síndrome de nanismo e raquitismo (RSS)
Resumo: A doença entérica é um problema multifatorial em galinhas que causa alterações gastrointestinais, conversão alimentar elevada e deficiência de crescimento. Nos últimos anos, os vírus entéricos foram associados à doença entérica; casos reportados mostraram a infecção de um único vírus e também infecções concomitantes durante os sur

4. A non-enteric adenovirus A12 gastroenteritis outbreak in Rio de Janeiro, Brazil
A gastroenteritis outbreak that occurred in 2013 in a low-income community in Rio de Janeiro was investigated for the presence of enteric viruses, including species A rotavirus (RVA), norovirus (NoV), astrovirus (HAstV), bocavirus (HBoV), aichivirus (AiV), and adenovirus (HAdV). Five of nine stool samples (83%) from patients were positive for HAdV, and no ot

5. The role of human adenoviruses type 41 in acute diarrheal disease in Minas Gerais after rotavirus vaccination
Abstract Human adenovirus species F (HAdV-F) type 40 and 41 are commonly associated with acute diarrheal disease (ADD) across the world. Despite being the largest state in southeastern Brazil and having the second largest number of inhabitants, there is no information in the State of Minas Gerais regarding the role of HAdV-F in the etiology of ADD.

6. The prevalence of norovirus, astrovirus and adenovirus infections among hospitalised children with acute gastroenteritis in Porto Velho, state of Rondônia, western Brazilian Amazon
Although viruses are well-established causes of acute gastroenteritis, few data on the circulation of these pathogens in Porto Velho, state of Rondônia, Brazil, are available. Thus, faecal samples from hospitalised diarrhoeic children, under six years of age, were collected and tested for the presence of norovirus (NoV), adenovirus (AdV) and astrovirus (Ast

8. Acute gastroenteritis and enteric viruses in hospitalised children in southern Brazil: aetiology, seasonality and clinical outcomes
Viral acute gastroenteritis (AG) is a significant cause of hospitalisation in children younger than five years. Group A rotavirus (RVA) is responsible for 30% of these cases. Following the introduction of RVA immunisation in Brazil in 2006, a decreased circulation of this virus has been observed. However, AG remains an important cause of hospitalisation of p

9. Genotyping of gastroenteric viruses in hospitalised children: first report of norovirus GII.21 in Brazil
This retrospective study (April-September 2003) was designed to investigate the roles of the main viruses responsible for cases of acute infantile gastroenteritis in hospitalised children up to two years of age. The viruses were identified in 64.7% (88/136) of the cases and the detection rates of rotavirus A (RVA), norovirus (NoV) and astrovirus were 41.9% (

10. Viral acute gastroenteritis: clinical and epidemiological features of co-infected patients
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-p

12. Molecular characterization of viruses associated with gastrointestinal infection in HIV-positive patients
BACKGROUND: Diarrhea is a major cause of morbidity and mortality among HIV-infected patients worldwide. OBJECTIVE: We sought to determine the frequency of viral gastrointestinal infections among Brazilian HIV-infected patients with diarrhea. METHODS: A collection of 90 fecal specimens from HIV-infected individuals with diarrhea, previously tested for the pre
