1. Soil contamination of a public park by human and canine mastadenovirus, as well as hookworms and Toxocara spp eggs
ABSTRACT Public parks are leisure environments widely used by both, adults and children, often accompained by their pets. Soil contamination of these environments by enteric viruses and intestinal parasites occurs through these animals feces. The aim of this work was to detect Carnivore protoparvovirus 1 (CPV-1) and different species of Mastadenovirus in soi

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. Could human coronavirus OC43 have co-evolved with early humans?
Abstract This paper reports on an investigation of the role of codon usage evolution on the suggested bovine-to-human spillover of Bovine coronavirus (BCoV), an enteric/respiratory virus of cattle, resulting in the emergence of the exclusively respiratory Human coronavirus OC43 (HCoV-OC43). Analyses based on full genomes of BCoV and HCoV-OC43 and on both hum

4. Investigation of Enteric Viruses in the Feces of Neotropical Migratory Birds Captured on the Coast of the State of Pará, Brazil
ABSTRACT Migratory birds can become long-distance vectors for a wide range of microorganisms and can cause human disease, being the Brazilian coast a gateway for northern migratory birds. These animals are considered natural reservoirs of different viruses that cause important diseases, being relevant research of viral pathogens in migratory birds to epidemi

5. 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

6. Bioaccumulation of animal adenoviruses in the pink shrimp
Adenoviruses are among the most promising viral markers of fecal contamination. They are frequently found in the water, sediment and soil of regions impacted by human activity. Studies of the bioaccumulation of enteric viruses in shrimp are scarce. The cities located in the northern coast of the lake systems in Southern Brazil have high urbanization and i

7. Enteric viruses in turkey flocks: a historic review
In this review, diagnostic techniques and viral agents involved in enteric diseases affecting turkeys are described. Data from field observations and laboratory researches have been reported in turkey flocks for over 70 years, and several viruses have been identified. After a period of 30 years of inoculation experiments and neutralization studies, adequate

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. Detection of enteric viruses in activated sludge by feasible concentration methods
Human enteric viruses are responsible to cause several diseases, including gastroenteritis and hepatitis, and can be present in high amounts in sewage sludge. This study compared virus recovery efficiency of two feasible concentration methods used for detecting human adenovirus (HAdV), rotavirus species A (RV-A), norovirus genogroup II (NoV GII) and hepatiti

10. The efficiency of concentration methods used to detect enteric viruses in anaerobically digested sludge
The presence of enteric viruses in biosolids can be underestimated due to the inefficient methods (mainly molecular methods) used to recover the viruses from these matrices. Therefore, the goal of this study was to evaluate the different methods used to recover adenoviruses (AdV), rotavirus species A (RVA), norovirus genogroup II (NoV GII) and the hepatitis

11. Métodos clássicos e moleculares para avaliação da qualidade virológica de lodo de esgoto e de água de reúso: determinação da eficiência e limites de detecção. / Standard and molecular methods for surveillance of human enteric viruses in sludge and reclaimed water: efficiency and detections limits.
Os vírus entéricos humanos são encontrados no esgoto e em subprodutos dos processos de tratamento. Recentemente vem sendo recomendados como indicadores de qualidade microbiológica em normas da legislação brasileira e também nas de outros países, mas ainda com parâmetros a definir. O objetivo do estudo é a avaliação e a comparação entre métodos

12. Detection of enteric viruses in recreational waters of an urban lagoon in the city of Rio de Janeiro, Brazil
The aim of this study was to determine the occurrences of the group A rotavirus (RVA), norovirus (NoV) and human adenovirus (HAdV) in the surface waters of an urban lagoon (Rodrigo de Freitas Lagoon) in the city of Rio de Janeiro, Brazil. During one year of surveillance, water samples were obtained from the lagoon and other interconnected ecosystems (river a
