Emergence of intragenotype recombinant sapovirus in Japan
Infection, Genetics and Evolution, 2007 Sapovirus is an important causative agent of sporadic cases as well as of outbreaks of acute gastroenteritis in humans worldwide. A total of 603 fecal specimens collected from July 2005 to June 2006 from children with acute gastroenteritis in five localities in Japan (Maizuru, Tokyo, Sapporo, Saga, and Osaka) were screened for sapovirus by RT-PCR.

The real-time detection of sapovirus
Journal of Clinical Virology, 20061 d n the UK (Simpson et al., 2003). Sapovirus is thought to e the least common of the main viral causes of IID but it s rarely tested for in the UK. Consequently the true burden f sapovirus has yet to be determined. Sensitive diagnosis is mportant as it improves patient management and the utility of ational surveillance data.

Genetic diversity of human sapovirus across the Americas
Journal of Clinical Virology, 2018Background: 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.

Sapovirus-like particles derived from polyprotein
Virus Research, 2008We expressed full-length sapovirus genome constructs in insect cells and analyzed their products. The capsid protein was cleaved from the ORF1 polyprotein from a native-like genome construct and two full-length genome constructs with mutations in an active polymerase motif, whereas the capsid protein was not cleaved from a full-length genome construct ...

Intrahost viral evolution during chronic sapovirus infections
Journal of Clinical Virology, 2019Sapovirus is a common cause of self-limiting diarrhea. In immunocompromised individuals chronic infections occur, but are incompletely investigated.To investigate viral evolution in immunocompromised hosts during chronic sapovirus infection.From January 2010 to September 2018 stool samples of 5333 in-patients were analyzed for the presence of sapovirus

Genetic variability in the sapovirus capsid protein
Virus Genes, 2006Sapovirus (SV), which causes gastroenteritis in humans, is composed of genetically divergent viruses classified into 5 genogroups. In this study, 2.2-kb nucleotide sequences of the 3' terminus of the genome of 15 SV strains detected in Japan were determined. The 15 SV strains could be classified into four genogroups (GI, GII, GIV and GV), and in two of

Cross-reactivity among sapovirus recombinant capsid proteins
Archives of Virology, 2004Sapovirus (SaV), a member of the genus Sapovirus in the family Caliciviridae, is an agent of human and porcine gastroenteritis. SaV strains are divided into five genogroups (GI-GV) based on their capsid (VP1) sequences. Human SaV strains are noncultivable, but expression of the recombinant capsid protein (rVP1) in a baculovirus expression system ...
