Discovery and Genomic Characterization of a Novel Bat Sapovirus with Unusual Genomic Features and Phylogenetic Position [PDF]

PLoS ONE, 2012
Sapovirus is a genus of caliciviruses that are known to cause enteric disease in humans and animals. There is considerable genetic diversity among the sapoviruses, which are classified into different genogroups based on phylogenetic analysis of the full ...

Genetic Diversity of Sapovirus in Children, Australia [PDF]

Emerging Infectious Diseases, 2006
Sapovirus was detected in 7 of 95 stool specimens from children with gastroenteritis of unknown etiology in Sydney, Australia, from August 2001 to August 2002 and from February 2004 to August 2004, by using reverse transcription–polymerase chain reaction.

Human Sapovirus in Clams, Japan [PDF]

Emerging Infectious Diseases, 2007
Human sapovirus was detected in 4 of 57 clam packages by reverse transcription–PCR and sequence analysis. This represents the first finding of sapovirus contamination in food. Closely matching sequences have been detected in stool specimens from patients

Novel Recombinant Sapovirus [PDF]

Emerging Infectious Diseases, 2004
We determined the complete genome sequences of two sapovirus strains isolated in Thailand and Japan. One of these strains represented a novel, naturally occurring recombinant sapovirus.

Novel Recombinant Sapovirus, Japan [PDF]

Emerging Infectious Diseases, 2006
To the Editor: Sapovirus is the distinct genus within the family Caliciviridae; these viruses cause sporadic cases and outbreaks of gastroenteritis in humans worldwide (1). The sapovirus genome contains 2 open reading frames (ORFs). ORF1 encodes nonstructural and capsid proteins while ORF2 encodes a small protein (2).

Intergenogroup Recombinant Sapovirus in Japan, 2007–2008 [PDF]

Emerging Infectious Diseases, 2009
We investigated the incidence of sapovirus (SaV)–associated gastroenteritis in infants and children in Japan during 2007–2008 and characterized the diversity of SaV-positive strains. SaV was detected in 19 (4%) of 477 fecal specimens.

Genetic diversity of human sapovirus across the Americas

Journal of Clinical Virology, 2018
Background: Sapoviruses are responsible for sporadic and epidemic acute gastroenteritis worldwide. Sapovirus typing protocols have a success rate as low as 43% and relatively few complete sapovirus genome sequences are available to improve current typing protocols.

Recombinant Sapovirus Gastroenteritis, Japan [PDF]

Emerging Infectious Diseases, 2007
To the Editor: Sapovirus and norovirus are causative agents of gastroenteritis in children and adults. Norovirus is the most important cause of outbreaks of gastroenteritis, whereas only a few outbreaks of sapovirus have been reported (1,2). On the basis of complete capsid gene sequences, sapovirus can be divided into 5 genogroups, among which GI, GII,

Partial Analysis of the Capsid Protein (VP1) of Human Sapovirus Isolated from Children with Diarrhoea in Rural Communities of South Africa [PDF]

Advances in Virology, 2022
Background. Viral diarrhoea is a concern in acute gastroenteritis cases among children younger than 5 years of age. Sapovirus has been noted as an emerging causative agent of acute gastroenteritis worldwide. Objective/Study Design.

Proteolytic Processing of Sapovirus ORF1 Polyprotein [PDF]

Journal of Virology, 2005
ABSTRACT The genome of Sapovirus (SaV), a causative agent of gastroenteritis in humans and swine, contains either two or three open reading frames (ORFs). Functional motifs characteristic to the 2C-like NTPase (NTPase), VPg, 3C-like protease (Pro), 3D-like RNA-dependent RNA polymerase (Pol), and capsid ...
