“…Rotaviruses are an important etiologic agent of severe diarrhea among infants and young children, as well as the young of many species of animals. For instance, the bovine rotavirus was isolated from cattle worldwide (Hayashi-Miyamoto et al, 2017;Papp et al, 2013). The human rotavirus was found in humans by Bishop et al (1979), and in the next year the porcine rotavirus was isolated from infected pigs by Woode et al (1976).…”

Porcine rotavirus (PoRV) is one of the major causes of neonatal diarrhea in swine worldwide. Multiple serotypes of PoRV have been detected in diarrhea cases of suckling and weaning pigs. To date, the prevalence and molecular characterizations of PoRV circulating in swine in Shandong province of China remains largely unknown. Two hundred and twenty-six feces samples were collected from ten farms showing diarrhea in Shandong. All the samples were tested by RT-PCR for the presence of PoRV, TGEV, or PEDV. The results showed that all farms are positive for PEDV, and 60% and 10% of the farms are positive for PoRV and TGEV respectively. PoRV was detected in 65 out of 226 (28.76%) samples collected from 1-3 months old suckling and weaning pigs, while the positive rates of the TGEV and PEDV were 2.21% and 34.96%, respectively. The present data emphasized that PoRV is an important pathogen causing diarrhea in swine in China. In addition, VP6 and VP7 genes of PoRVs were sequenced and analyzed. Phylogenetical analysis of VP6 showed that all of the five PoRVs belong to group A rotavirus, meanwhile VP7 genes belong to the G3, G5, and G9 genotypes. Moreover, G5 and G9 genotypes are the dominant genotypes. Taken together, co-infections of TGEV, PEDV, and PoRV occur in pig population in Shandong, and the multiple serotypes of PoRVs are circulating in those herds, suggesting the active surveillance and matched vaccine application.

“…RVB strains can cause sporadic or epidemic diarrhoea in humans [ 6 ] and a variety of animals, including sheep [ 7 ], goats, cows, pigs and rats [ 8 ]. In addition, RVB infections have been identified in multiple countries, including Bangladesh [ 9 ], Brazil [ 10 ], China [ 6 ], the Czech Republic [ 11 ], India [ 12 ], Japan [ 13 ], New Zealand [ 14 ], Spain [ 15 ], the USA [ 16 ] and the UK [ 17 ], by genetic and/or serological methods.…”

Rotavirus B (RVB) has been associated with enteric disease in many animal species. An RVB strain was identified in pooled intestinal samples from Alpine caprine kids (between 2 and 3 days of age) experiencing high (>90 %) morbidity, and the complete caprine RVB genome was characterized. Histology revealed villus atrophy, the samples tested positive for RVB by real-time RT-PCR and metagenomic next-generation sequencing identified only RVB and orf virus. In the VP4 gene segment, the caprine RVB strain had a higher percentage nucleotide identity to the Indian bovine RVB strains than to the Japanese bovine RVB strains, but the VP7, VP6, VP2, NSP1, NSP2 and NSP5 gene segments of the American caprine RVB strain were genetically related to the Japanese bovine RVB strains. The results indicate a lack of RVB sequences to understand reassortment or the evolutionary relationship of RVB strains from cattle and goats.

“…Their identity was found to be between around 52%À68% between human, murine, and porcine RVBs. Analysis and comparative studies were revealed for the independent evolutions of bovine RVBs (Hayashi-Miyamoto et al, 2017). In the Asia-Pacific region, a number of picornaviruses have been discovered in various hosts like bats, canines, felines, etc., in quick succession.…”
