“…The correlation of PBV diagnosis in feces with altered consistency (diarrheic and pasty) collected from these animals with clinical signs of the enteritis was significant (P \ 0.05) when compared with normal (control) feces [73]. Costa et al [17] also detected the virus in low- frequency in samples from dogs with gastroenteritis (3/163 vs 1.84 %).…”

“…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 …”

“…In another study, intestines from a total of 227 chickens slaughtered in Rio de Janeiro, Brazil by PAGE assay showed 30 (13.21 %) of PBVs [59]. A total of 378 fecal samples from 1 to 7 weeks old broiler chickens analyzed by PAGE assay resulted in detection of 13 (3.4 %) PBVs at Parana state, Brazil [73] and statistically significant correlation was seen between PBV shedding and altered consistency of faeces (diarrheic and pasty) with clinical signs of the enteritis [73].…”

“…In rabbits, Gallimore et al [25] detected PBV more commonly in newly weaned rabbits than in young adults. Tamehiro et al [73] detected excretion of PBV in broiler chickens 2-7 weeks old and Masachessi et al [57] detected PBV in fecal specimens obtained from asymptomatic rheas (American ostrich: Rhea americana) approximately 3 weeks old. According to the data obtained from all these studies mentioned above, the primary PBV infection could take place between the first few weeks of life in animals and birds.…”

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.

“…Since the first report in avian species by Bergeland et al (1977), it has become apparent that rotavirus infects many species of domesticated bird. In field conditions, rotavirus infections in poultry may induce subclinical manifestations, or they may be associated with enteritis, dehydration, anorexia, low weight gain, and increased mortality (McNulty, 2003;Tamehiro et al, 2003). It may also vary from a mild disease in young chickens to a more severe manifestation in 12 to 21-day-old chickens, characterized by unrest, litter ingestion; watery feces, wet litter, and severe diarrhea (Barnes, 1997).…”

Rotaviruses classified into groups A through H are important etiological agents of gastroenteritis in man and animal. In Nigeria vaccination of infants has continuously been carried out, however the disease is still a burden to the nation which remains one of the countries with the highest cases of rotavirus gastroenteritis. There are several evidence of interspecies cross transmission and reassortment among group A rotaviruses. However, few studies have focused on rotavirus in the avian species, thus the virus has only been reported in chickens from southwest Nigeria. Guinea fowls (Numidea meleagris) and Japanese quails (Coturnix corturnix japonica) serve as source of income to the rural house-hold where they are raised in backyards. A total of 100 fecal samples from Guinea fowls (50) and Japanese quails (50) from different locations in Ogun state were collected and analyzed using group A specific RT-PCR. Fecal samples were screened for rotavirus using VP7 primers. The virus was detected in pooled diarrheic fecal samples of both Guinea fowls and Japanese quails and also in non-diarrheic feces of Guinea fowls. Due to the close proximity at which different breeds of birds are raised in backyard poultry in Nigeria and the reassortment ability of the virus, there will continuously be an increase in the diversity of the virus. This is not leaving out a zoonotic transmission with subsequent contribution to vaccine failure in man. It is thus important to continually survey for the virus in man and animal. This study provides the first report of rotavirus in helmeted Guinea fowls and Japanese quails in Nigeria.

Picobirnaviruses (PBVs) are small, non-enveloped, bisegmented double-stranded RNA genomic viruses of vertebrate hosts. Since their discovery in the late 1980s in clinical specimens from outbreaks of acute gastroenteritis in children, significant efforts have been made to investigate the role of PBV in diarrheic diseases. PBV has been detected in sporadic episodes of diarrhea as sole pathogen or coinfection as well as in outbreaks of acute gastroenteritis and in immunocompromised patients with diarrhea. However, PBV is frequently detected in non-diarrheic healthy hosts, and prolonged shedding has been observed in some individuals. Of interest, similar patterns of PBV infection have also been observed in pigs and other animal hosts. The increasing amount of PBV sequence data gathered from molecular epidemiological studies has evidenced a great sequence diversity of PBVs in various hosts and environmental samples. Importantly, evidence has been found for genetic relatedness between human and animal PBV strains, suggesting extant crossing points in the ecology and evolution of heterologous PBV strains. At present, no cell culture and animal model exists for PBVs. Well-structured epidemiological studies are still the only alternative to demonstrate the potential etiological role of PBVs in acute gastroenteritis or other diseases. This review aims to analyze the public health aspects of PBV infection, especially its possible association with zoonosis.
