Article Synopsis
- The study focuses on analyzing Brazilian rotavirus strains G12P[6] and G12P[9] from 2011 to 2020 to understand genetic relationships between human and animal-origin strains using RT-PCR and sequencing techniques.
- Findings indicate that G12P[6] strains show distinct genetic clustering and are associated with African ancestry and American strains, while G12P[9] strains exhibit unique lineages found only in Brazil, suggesting local evolution.
- The results highlight a common origin for South American G12P[9] strains, supporting the idea of their introduction from Asia, with no recent reassortments from globally circulating strains.
This study aimed to investigate the frequency and genotypic diversity of human bocavirus (HBoV) in historical fecal samples collected before 2005 in Brazil and understand its natural history in patients with diarrhea. Between 1998 and 2005, 3347 samples were tested for HBoV by RT-PCR, with a detection rate of 5.8% (195/3347).

The aim of this study was to monitor rotavirus infections in household dogs and cats, determine full-genotype constellations, and obtain data on evolutionary relationships. Between 2012 and 2021, 600 fecal samples from dogs and cats (516 and 84, respectively) were collected at small animal clinics in São Paulo state, Brazil.

The aim of this study was to investigate HEV presence in free-living capybaras inhabiting urban parks in São Paulo state, Brazil. Molecular characterization of HEV positive samples was undertaken to elucidate the genetic diversity of the virus in these animals.

- Capybaras, the largest rodents in the world, are highly adaptable to urban environments in South America and can carry various zoonotic diseases.
- A study conducted in São Paulo, Brazil, aimed to check for the presence of fecal-borne viruses in capybara feces by collecting 337 samples from 2018 to 2020 and testing for multiple virus types.
- Results showed all samples tested negative for fecal-borne viruses, suggesting that they pose a minor public health risk in the studied areas, but ongoing monitoring of wildlife is vital to manage potential viral threats.
