The picobirnavirus crystal structure provides functional insights into virion assembly and cell entry [PDF]

The EMBO Journal, 2009
Double-stranded (ds) RNA virus particles are organized around a central icosahedral core capsid made of 120 identical subunits. This core capsid is unable to invade cells from outside, and animal dsRNA viruses have acquired surrounding capsid layers that are used to deliver a transcriptionally active core particle across the membrane during cell entry.

Occurrence of avian reovirus and picobirnavirus in wild birds from an environmental protection area in the Brazilian Amazon [PDF]

Acta Amazonica
Wild birds have great prominence in the transmission of diseases to humans, mainly due to their ease of access to human populations, raising concerns about the potential impact of that proximity on public health.

Genogroup I picobirnavirus in diarrhoeic foals: Can the horse serve as a natural reservoir for human infection?

Veterinary Research, 2011
Picobirnaviruses (PBV) are small, non-enveloped viruses with a bisegmented double-stranded RNA genome. In this study a PBV strain, PBV/Horse/India/BG-Eq-3/2010, was identified in the faeces of a 10 month old weaned female foal with diarrhoea in January ...

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.

Re-emergence of porcine epidemic diarrhea virus in a piglet-producing farm in northwestern Germany in 2019

BMC Veterinary Research, 2020
Background Porcine epidemic diarrhea (PED) is a viral enteric disease of pigs. It affects all age classes of animals but lethality is mainly seen in suckling piglets.

Picobirnavirus detection in bovine and buffalo calves from foothills of Himalaya and Central India [PDF]

Tropical Animal Health and Production, 2011
The present study describes detection of picobirnavirus (PBV) in faecal samples from bovine and buffalo calves employing the polyacrylamide gel electrophoresis (PAGE). A total of 136 faecal samples from buffalo (n = 122) and cow calves (n = 14) exhibiting clinical signs of diarrhoea and from healthy calves were collected during 2007-2010 from ...

High detection rate and genetic diversity of picobirnavirus in a sheep flock in Brazil

Virus Research, 2018
This study reports the detection by RT-PCR and molecular characterization of partial RdRp gene of picobirnavirus (PBV) dsRNA in fecal samples (n = 100) from a meat sheep flock in southern Brazil. The analysis of the results allowed the identification of two important characteristics of PBV infection. The first was the high frequency of infection in the

Cloning of Human Picobirnavirus Genomic Segments and Development of an RT-PCR Detection Assay

Virology, 2000
Nearly full-length genomic segments 2 and a partial-length genomic segment 1 of human picobirnavirus were cloned and sequenced. The clones were derived from viruses obtained from human immunodeficiency virus (HIV)-infected patients in Atlanta, Georgia (strains 3-GA-91 and 4-GA-91) and a nonHIV-infected person from China (strain 1-CHN-97).

Simultaneous identification of DNA and RNA viruses present in pig faeces using process-controlled deep sequencing.

PLoS ONE, 2012
BackgroundAnimal faeces comprise a community of many different microorganisms including bacteria and viruses. Only scarce information is available about the diversity of viruses present in the faeces of pigs.

Molecular detection of human enteric viruses circulating among children with acute gastroenteritis in Valencia, Venezuela, before rotavirus vaccine implementation

Gut Pathogens, 2018
Background The role of rotavirus as main etiologic agent of diarrhea has been well documented worldwide, including in Venezuela. However, information about the prevalence of gastrointestinal viruses such as calicivirus, adenovirus and astrovirus is ...
