Identification of a bisegmented double-stranded RNA virus (picobirnavirus) in calf faeces

Veterinary Journal, 2003
To determine the incidence of rotavirus infection among dairy herds in the State of São Paulo, Brazil, 576 faecal samples obtained from calves aged 1-45 days with and without diarrhoea, reared on 63 dairy cattle farms, were analyzed. Polyacrylamide gel electrophoresis (PAGE) identified 28 samples positive for group A rotavirus, while four samples, two ...

The Picobirnavirus: an Integrated View on its Biology, Epidemiology and Pathogenic Potential

Future Virology, 2011
Picobirnaviruses (PBV) are a group of small, nonenveloped viruses with bi-segmented dsRNA genomes. The large genomic segment encodes for the capsid protein while the small segment encodes for the RNA-dependent RNA polymerase. PBV are widely distributed and have been detected in the feces of a large variety of vertebrate species, including farm and ...

Circulation of picobirnavirus in Neotropical free-ranging mammals

Veterinary Research Communications, 2023
Picobirnavirus (PBV) is a family of non-enveloped double-stranded RNA viruses with bisegmented genomes. Segment 1 encodes the capsid protein and segment 2 encodes RNA-dependent RNA polymerase. They exhibit high genomic heterogeneity and infect a wide range of vertebrate hosts, including humans. The objective of this study was to expand our knowledge of

Nomenclature proposal for picobirnavirus

Archives of Virology, 2009
Picobirnaviruses have been identified in the feces of a broad range of hosts by several international research groups. Because there is no standard nomenclature for these viruses, we propose a clear and unique name for each strain.

Genomic characterisation of the large segment of a rabbit picobirnavirus and comparison with the atypical picobirnavirus of Cryptosporidium parvum

Archives of Virology, 1999
The 2362 base pair sequence of the larger of the two double stranded RNA genome segments of a rabbit strain of picobirnavirus (PBV) has a major open reading frame (ORF) of 591 amino acids and two smaller ORFs of 55 and 155 amino acids. A clone of the segment did not hybridise with other viral bisegmented ds RNAs from faecal samples.

Molecular Detection and Characterization of Picobirnavirus in Environmental Water in Thailand

Clinical Laboratory, 2020
Enteric viruses are responsible for waterborne and foodborne infections affecting a large number of people around the world. Picobirnavirus (PBV) is a highly versatile virus, detected in a wide range of hosts and has been reported to be associated with gastroenteritis in humans and animals.Molecular screening of environmental water samples for PBV was ...

Picobirnavirus infections: viral persistence and zoonotic potential

Reviews in Medical Virology, 2012
SUMMARYPicobirnaviruses (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

Detection of Picobirnavirus in HIV-Infected Patients With Diarrhea in Argentina

Journal of Acquired Immune Deficiency Syndromes and Human Retrovirology, 1998
Diarrhea due to enteric pathogens is an important complication of advanced HIV infection. Picobirnaviruses are agents recently linked with human enteritis. In total, 197 fecal samples collected from HIV-infected and noninfected patients with and without diarrhea were investigated for the presence of rotavirus and picobirnavirus by polyacrylamide gel ...

Molecular and Phylogenetic Analysis of a Novel Turkey-Origin Picobirnavirus

Avian Diseases, 2014
A previous metagenomic analysis of the turkey gut RNA virus community identified novel enteric viruses that may play roles in poultry enteric diseases or in performance problems noted in the field. As part of the molecular characterization of these novel enteric viruses, a reverse transcriptase-PCR diagnostic assay was developed, targeting a novel ...

Detection of a picobirnavirus associated withCryptosporidium positive stools from humans

Archives of Virology, 1995
A picobirnavirus with an atypical genome profile was detected by polyacrylamide gel electrophoresis (PAGE) in 37% (20/54) of human faecal samples also containing oocysts of Cryptosporidium typical of C. parvum. This virus shares many of the characteristics of the previously described picobirnaviruses, but has a significantly smaller genome (1.75 and 1 ...
