Prevalence of group C rotaviruses in weaning and post-weaning pigs with enteritis

Abstract: 1Diarrheic fecal specimens collected from porcine herds were screened for the presence of 2 group C rotaviruses using a reverse transcription-polymerase chain reaction assay. A total of 3 188 samples were tested and 54 were positive. When compiled these data with diagnostic 4 results on group A rotaviruses and enteric caliciviruses we found that all but 5 group C 5 rotavirus positive samples contained at least one additional virus. A subset of samples were 6 subjected to nucleotide sequencing. The selected str… Show more

“…The majority of the surveys evaluated only one pathogen, resulting in insufficient information about the frequency and severity of diarrhea caused by concomitant infections with multiple enteropathogens (Barreiros et al 2003, Linares et al 2009); however, more recently some studies have identified several different enteric agents in pig fecal samples (Martella et al 2007, Jeong et al 2009, Halaihel et al 2010, Médici et al 2011, Marthaler et al 2012. In Brazil, the association of different PoRV groups in piglet enteritis has been reported in transversal epidemiological studies carried out in distinct pig farms, not all of which were involved in a diarrhea outbreak (Médici et al 2011).…”

“…PoRVC has been described as a cause of diarrhea outbreaks in weaning and post-weaning pigs, which in some cases leads to substantial morbidity rates (Morin et al 1990, Kim et al 1999, Martella et al 2007). Single infections of PoRVC have been detected in piglets, but this PoRV group was more frequently detected in piglets in association with other PoRV groups or with other enteric viruses (Médici et al 2011, Marthaler et al 2012.…”

“…Nowadays, Rotavirus strains are classified into five main (A, B, C, D, E) and two additional tentative (F, G) serotype groups (or serogroups) on the basis of antigenic sites located on the VP6 protein (Ball, 2005;Estes and Kapikian, 2007;Matthijnssens et al, 2012;Otto et al, 2012). Strains classified into serogroup A, B or C have been found to be pathogenic for various animal species and humans; serogroup E strains have been isolated only from pigs; serogroup D, F or G strains have been isolated only from avian species (Saif and Jiang, 1994;Dhama et al, 2009;Martella et al 2007;Matthijnssens et al, 2011b). Most virulent and commonly isolated strains belong to serogroup A (GARVs); they are an important cause of acute infectious diarrhoea in children and various domestic mammalian and avian species.…”
