Evidence of closely related picobirnavirus strains circulating in humans and pigs in Argentina

Journal of Infection, 2011
On the basis of the published literature, it is still difficult to draw conclusions as to whether picobirnavirus (PBV) circulation is influenced by host species restriction.To provide data regarding the genetic relatedness between porcine and human PBV strains present in Argentina as a means of defining the host range and epidemiology of these viruses ...

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

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 ...

Identification of picobirnavirus from faeces of Italian children suffering from acute diarrhea [PDF]

European Journal of Epidemiology, 1996
Polyacrylamide gel electrophoresis of nucleic acid extracted from stool samples of diarrhoeic children revealed in 3 out of 690 (0.43%) specimens two electrophoretic bands with a migration pattern characteristic of picobirnavirus ds-RNA. In none of the 92 control children were similar bands detected.

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 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 ...

Prevalence and molecular characterization of porcine Picobirnavirus in piglets of North East Region of India [PDF]

Tropical Animal Health and Production, 2016
Picobirnaviruses (PBVs) have been recognized as one of the important causal viral agents of gastroenteritis in several animal species especially in young immunocompromised hosts. In this study, we report the prevalence and molecular epidemiology of porcine PBVs from North Eastern Hilly region of India.

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 ...
