Article Synopsis
- Acute gastroenteritis (AGE) is a major health issue for children worldwide, particularly in low-income areas, and this study focused on detecting human adenovirus (HAdV) and non-polio enterovirus (NPEV) in fecal samples from affected children.
- Out of 801 tested samples, HAdV was found in 31.7% and NPEV in 10.5%, with co-detection in 5.4%, highlighting significant viral presence in cases of gastroenteritis.
- The research identified five HAdV species and three NPEV species, with a notable prevalence of HAdV-F41 and specific NPEV serotypes, indicating a diverse viral landscape in the
Viral gastroenteritis is commonly reported in dogs and involves a great diversity of enteric viruses. In this research, viral diversity was investigated in dogs with diarrhea in Northern Brazil using shotgun metagenomics. Furthermore, the presence of norovirus (NoV) was investigated in 282 stool/rectal swabs of young/adult dogs with or without diarrhea from two public kennels, based on one-step reverse transcription polymerase chain reaction (RT-PCR) for genogroup VI and VII (GVI and GVII) and real-time RT-PCR for GI, GII, and GIV.

In the present study, the CanCV was detected by PCR in 15% (22/147) of dogs from animal shelters in Belém, between 2019 and 2020. We observed an association between the CanCV infection and the presence of diarrhea in animals younger than one year of age (p > 0.

It mainly affects dogs in the first 6 months of life, and these animals are considered an important reservoir and potential transmitters of the virus to other susceptible hosts, such as humans. Among the different types of RVA, G3 is the most detected in dogs, and this genotype is also involved in infections in other animals, including humans.

- This study investigated norovirus (NoV) in recreational waters of four beaches on Mosqueiro Island, Brazil, over two years (2012-2013) using semi-nested RT-PCR techniques.
- Findings revealed that NoV was present in 37.5% of water samples, with the genogroup GI being more common than GII, and the highest detection rate occurred at Paraíso Beach during high tide.
- The research indicated a link between rainfall, tide levels, and NoV detection rates, underlining the health risks for beachgoers and the need for monitoring enteric viruses in water quality assessments.
Detection and genotyping of enteric viruses in hospitalized children with acute gastroenteritis in Belém, Brazil: Occurrence of adenovirus viremia by species F, types 40/41.

March 2019
Enteric adenovirus (AdV), sapovirus (SaV), and human astrovirus (HAstV) are important pathogens involved in the gastroenteritis etiology. In this study, a total of 219 fecal samples and sera were collected from children hospitalized for acute gastroenteritis (AGE) in two large pediatric hospitals in Belém, from March 2012 to April 2015. The samples were analyzed by polymerase chain reaction (PCR) for AdV and HAstV (astrovirus) detection, and Nested-PCR and qPCR for SaV detection.
