Cross-reactivity among sapovirus recombinant capsid proteins

Archives of Virology, 2004
Sapovirus (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 ...

Propagating and banking genetically diverse human sapovirus strains using a human duodenal cell line: investigating antigenic differences between strains

Journal of Virology
There are four genogroups and 18 genotypes of human sapoviruses (HuSaVs) responsible for acute gastroenteritis. To comprehend their antigenic and virological differences, it is crucial to obtain viral stocks of the different strains.

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.

Biochemical characterization of Sapovirus 2C helicase and identification of pramipexole as a novel inhibitor in vitro.

Bioorganic chemistry (Print)
Sapovirus (SaV) is a major causative agent of acute gastroenteritis in both humans and animals. The virally encoded 2C helicase, which shares low homology with host helicases, represents a promising target for the development of broad-spectrum antiviral ...

Novel intragenotype recombination in sapovirus.

Clinical laboratory, 2006
Based on the genetic analysis, a novel, naturally occurring recombination between two distinct sapovirus subtypes (subtype a and subtype b) within genogroup I genotype 1 was identified. Breakpoint analysis of recombinant sapovirus showed that the recombination site was at the polymerase-capsid junction.

Novel recombinant sapovirus in Bangladesh.

Clinical laboratory, 2011
Recombination of RNA viruses plays an important part in molecular epidemiological study, virus evolution, vaccine design, and viral control programs. Sapovirus, a member of the family Caliciviridae, is one of the major causative agents of viral gastroenteritis affecting all age groups.Sapovirus capsid and polymerase regions were amplified by PCR using ...
