Abstract: Porcine group A rotavirus (PoRVA) is a major cause of neonatal diarrhea in suckling and recently weaned piglets worldwide. The involvement of non-group A rotavirus in cases of neonatal diarrhea in piglets are sporadic. In Brazil there are no reports of the porcine rotavirus group C (PoRVC) as etiologic agent of the diarrhea outbreaks in piglets. The aim of this study was to describe the identification of rotavirus group C in single and in mixed infection with rotavirus groups A and B in three neonatal diarrhea… Show more

“…In this outbreak, clinical manifestations, epidemiologic feature, laboratory tests and genetic features of the agent in diarrhoeic piglets were noted. We found the crude attack rate was 61%, and RVA‐associated diarrhoea attack rate was higher (100%) among piglets than that reported (27%) in other study (Will et al, ); however, the case fatality rate (20%) was comparable to prior study (Lorenzetti et al, ).…”

“…Piglets generally recover in 1–2 weeks following infection but continue shedding the virus in faeces for up to 3 weeks (Svensmark, Askaa, Wolstrup, & Nielsen, ). Morbidity rates of RVA‐associated diarrhoea in piglets with diarrhoea range from 20% to 80% and mortality rates from 3% to 25% (Lorenzetti et al, ; Will et al, ).…”

“…However, very little is known about whole analyses of porcine RVA and genetic diversity and zoonotic potential in this country. Porcine RVAs analyzed to date have mainly exhibited G/P-genotypes of G5P (Barreiros et al, 2003;Gregori et al, 2009;Rácz et al, 2000;Tonietti et al, 2013), as well as have sporadically showed G4P[6] and G5P[23] genotypes (Lorenzetti et al, 2011(Lorenzetti et al, , 2014Tonietti et al, 2013). In this study, we performed whole-genome sequence analysis of porcine RVAs from 4 farms in Brazil.…”

“…Additionally, rotavirus has been detected by cross-reaction with the primers p289/p290 (Ludert et al 2004). Single and mixed infections with porcine rotavirus groups A, B and C are common in diarrhoeic suckling piglets and recently weaned pigs on Brazilian pig farms (Linares et al 2009;Médici et al 2011;Lorenzetti et al 2014). In this study, the 40 faecal samples positive for SaV were screened for rotavirus presence and no co-infections with these viruses were detected, likely because the faecal samples evaluated in this study were from asymptomatic animals.…”
