Full genotype characterization of Brazilian canine G3P[3] strains during a 10-year survey (2012-2021) of rotavirus infection in domestic dogs and cats.

There is a dearth of information on the molecular epidemiology of rotaviruses in pets in Brazil. 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.

Surveillance and molecular characterization of human sapovirus in patients with acute gastroenteritis in Brazil, 2010 to 2017.

Background: Human sapoviruses (HuSaV) are associated with acute gastroenteritis (AGE), causing sporadic cases and outbreaks in patients worldwide. In Brazil, however, there are few reports describing the prevalence of HuSaV in patients with AGE.

Objective: Describing the diversity of HuSaV in Brazil by detecting and molecularly characterizing HuSaV among patients with AGE during an 8-year period (2010-2017).

Surveillance and molecular characterization of human adenovirus in patients with acute gastroenteritis in the era of rotavirus vaccine, Brazil, 2012-2017.

Background: In Brazil, limited data are available regarding the incidence and molecular epidemiology of Human Adenovirus (HAdV) in diarrheic disease, especially in the post rotavirus (RVA) vaccine era.

Objective: The aims of the study were to investigate the frequency of HAdV infections in patients with gastroenteritis during a 6-year period (2012-2017); conduct molecular typing of positive strains, and obtain further information on the HAdV seasonality.

Study Design: A total of 3003 fecal samples negative for both, RVA and Norovirus, were selected and tested for HAdV by PCR.
