“…Later, PBVs have been identified in faecal specimens of humans practically worldwide [3, 6, 7, 14, 26-29, 51, 55, 56, 61, 68, 76]. PBVs were also detected in faeces of a wide variety of farm mammals, birds, wild animals and birds kept in captivity, etc., viz., pigs [2,4,16,31,34,50,56,67], calves [10,15,35,53,54,61,77,79], rabbits and guinea pigs [25,43,52,65], bats [86], red fox [8], avian such as chickens & poults [1,49,59,69,73], and other wild animals kept in captivity like Giant Anteaters [45]; giant cats like Lion, Puma, Jaguar and Geoffroy's cat [37], sea lion [84], human primates such as Orangutan, wild birds such as American Ostrich, gloomy pheasant, Chinese goose [57], goat kids and lambs [60], donkeys [57,58], foals [9,30], laboratory non-human primates such as rhesus, pigtailed macaques and cynomolgus monkeys [83] and dogs [17,23,81], rats [23,64], snakes [23] and turkeys …”

Picobirnavirus (PBV) is a small, non-enveloped, bisegmented double-stranded RNA (dsRNA) virus of vertebrate hosts. The name 'Picobirnavirus' derives from the prefix 'pico' (latin for 'small') in reference to the small virion size, plus the prefix 'bi' (latin for 'two') and the word 'RNA' to indicate the nature of the viral genome. The serendipitous discovery of PBV dates back to 1988 from Brazil, when human fecal samples collected during the acute gastroenteritis outbreaks were subjected for routine rotavirus surveillance by polyacrylamide gel electrophoresis (PAGE) and silver straining (S/S). The PAGE gels after silver staining showed a typical 'two RNA band' pattern, and it was identified as Picobirnavirus. Likewise, the feces of wild black-footed pigmy rice rats (Oryzomys nigripes) subjected for PAGE assay by the same research group in Brazil reported the presence of PBV (Pereira et al., J Gen Virol 69:2749-2754. PBVs have been detected in faeces of humans and wide range of animal species with or without diarrhoea, worldwide. The probable role of PBV as either a 'primary diarrhoeal agent' in 'immunocompetent children'; or a 'potential pathogen' in 'immunocompromised individuals' or an 'innocuous virus' in the intestine remains elusive and needs to be investigated despite the numerous reports of the presence of PBV in fecal samples of various species of domestic mammals, wild animals, birds and snakes; our current knowledge of their biology, etiology, pathogenicity or their transmission characteristics remains subtle. This review aims to analyse the veterinary and zoonotic aspects of animal Picobirnavirus infections since its discovery.

The Picobirnaviruses (PBVs) have been detected in several species of animals from different countries worldwide, including in South America. The host range of these viruses has increased in recent years; thus, in order to contribute to the knowledge in this topic we analyzed samples from captivity animals from Uruguay. We found the presence of PBVs in four species of animals, Panthera leo, Panthera onca, Puma concolor and Oncifelis geoffroyi, representing new PBV-susceptible hosts. All strains belonged to genogroup I.

“…After being reported in the year 1988 (Pereira et al, 1988b), PBVs have been detected in stools samples of several species of animals and from different countries, including rabbits (Gallimore et al, 1993;Ludert et al, 1995), dogs (Costa et al, 2004), cattle (Buzinaro et al, 2003;Malik et al, 2014;Vanpodenbosch and Wellemans, 1990), foals (Ganesh et al, 2011b), pigs (Bányai et al, 2008;Carruyo et al, 2008;Ganesh et al, 2012;Martínez et al, 2010), guinea pigs (Pereira et al, 1989), rats (Pereira et al, 1988a), monkeys (Wang et al, 2007), giant anteaters (Haga et al, 1999), orangutans, armadillos (Masachessi et al, 2007), Pantheraleo, Pantheraonca, Puma concolor, Oncifelis geoffroyi (Gillman et al, 2013), snakes (Fregolente et al, 2009), chickens (Tamehiro et al, 2003), geese, pheasants, pelicans (Masachessi et al, 2007) and humans (Gallimore et al, 1995;Ganesh et al, 2010Ganesh et al, , 2011aGiordano et al, 1998;Grohmann et al, 1993;Pereira et al, 1988b). PBVs have been detected in feces from animals with or without diarrhea (Bhattacharya et al, 2006(Bhattacharya et al, , 2007Gatti et al, 1989).…”
