Group A rotavirus (RVA) infections cause severe economic losses in intensively reared livestock animals, particularly in herds of swine and cattle. RVA strains are antigenically heterogeneous, and are classified in multiple G and P types defined by the two outer capsid proteins, VP7 and VP4, respectively. This study summarizes published literature on the genetic and antigenic diversity of porcine and bovine RVA strains published over the last 3 decades. The single most prevalent genotype combination among porcine RVA strains was G5P [7], whereas the predominant genotype combination among bovine RVA strains was G6P [5], although spatiotemporal differences in RVA strain distribution were observed. These data provide important baseline data on epidemiologically important RVA strains in swine and cattle and may guide the development of more effective vaccines for veterinary use. ß

Analysis of bovine rotavirus strains circulating in diarrheic dairy calves in Uberaba, Minas Gerais, Brazil, during 2008-2009

“…The rotavirus detection rate found in this study (6.8%) was similar to that (5%) observed in another study conducted in Brazil (Silva et al, 2012), but lower than the average (33.7%) determined in a recent review that included studies from five continents (Papp et al, 2013). The variations in prevalence rate may be a reflection of the differences between age, hygiene, and management conditions of animals in the studies.…”

“…Group A bovine rotavirus (BoRV-A) is considered as one of the main causes of this epidemic (Papp et al, 2013).…”

Genetic diversity in three bovine-like human G8P[14] and G10P[14] rotaviruses suggests independent interspecies transmission events

“…The detection of uncommon RVA genotypes in humans has been linked to the frequent intersections between the evolution of human and animal RVAs, as a result of numerous interspecies transmission events, sometimes accompanied by reassortment or adaptation to the new host (Degiuseppe et al, 2013;Martella et al, 2010;Weinberg et al, 2012). G6, G8 and G10 are the most common RVA G-genotypes encountered in cattle (Bányai et al, 2003;Matthijnssens et al, 2008;Papp et al, 2013). The P[14] RVA genotype has been detected sporadically in humans and is thought to be acquired through zoonotic transmission as it has been found in RVA strains from several distinct animal species, such as rabbits, cows, goats, sheep and guanaco.…”

Interspecies transmission of Rotaviruses among ruminants, dogs and humans: Current facts and remarks

“…In China, all three cases of Rotaviruses associated diarrhoea in lambs which have been reported P typing, P[5] strains (range, 37.1-50.0%) are the most prevalent in Europe, the Americas, Asia, and Australia followed by P[11] (range, 15.4-34.8%) and P[1] (2%) ; strains belonging to G1-G3, G5, and G11 and P[3], P[6], P [7], and P [14] have been also sporadically reported. A total of 20 individual G and P combinations have been described so far and three combinations, G6P[5], G6P[11], and G10P [11] are predominant (combined prevalence, 40%) in many areas worldwide (Papp et al, 2013;Doro et al, 2015). An unusual human G6P[14] Rotavirus strain was recently isolated from a child with diarrhoea in Thailand and the whole genome analysis revealed evidence for a bovine-to-human interspecies transmission and reassortment events (Tacharoenmuang et al, 2015).…”
