Detection of Sapovirus in oysters [PDF]

Microbiology and Immunology, 2010
SaV sequences which are either genetically identical or similar were detected from oysters, feces from gastroenteritis patients, and domestic wastewater samples in geographically close areas. This is the first report of the detection of SaV in oysters which meet the legal requirements for raw consumption in Japan.

Divergent Sapovirus Strains and Infection Prevalence in Wild Carnivores in the Serengeti Ecosystem: A Long-Term Study. [PDF]

PLoS ONE, 2016
The genus Sapovirus, in the family Caliciviridae, includes enteric viruses of humans and domestic animals. Information on sapovirus infection of wildlife is limited and is currently lacking for any free-ranging wildlife species in Africa.

Mutational study of sapovirus expression in insect cells [PDF]

Virology Journal, 2005
Abstract Human sapovirus (SaV), an agent of human gastroenteritis, cannot be grown in cell culture, but expression of the recombinant capsid protein (rVP1) in a baculovirus expression system results in the formation of virus-like particles (VLPs). In this study we compared the time-course expression of two different SaV rVP1 constructs.

Protective role of antibodies in enteric virus infections: Lessons from primary and secondary immune deficiencies. [PDF]

Immunol Rev
Summary Enteric viruses are the main cause of acute gastroenteritis worldwide with a significant morbidity and mortality, especially among children and aged adults. Some enteric viruses also cause disseminated infections and severe neurological manifestations such as poliomyelitis.

Distribution of Human Sapovirus Strain Genotypes over the last four Decades in Japan: a Global Perspective.

Japanese journal of infectious diseases (Print), 2023
Sapovirus (SaV) infections are a public health problem because they cause acute gastroenteritis in humans of all ages both as outbreaks and in sporadic cases. However, publicly-available SaV sequence information, especially whole genome sequences for all

Outbreak of Gastroenteritis Due to Sapovirus [PDF]

Journal of Clinical Microbiology, 2007
ABSTRACT An outbreak of gastroenteritis occurred at a kindergarten in Yokote City, Japan, between February 2006 and March 2006. Sapovirus was identified in 19 of 26 stool specimens by reverse transcription-PCR. A high viral shedding pattern was found for this strain, which was shown to be antigenically distinct from other genogroups.

Replication of Human Sapovirus in Human-Induced Pluripotent Stem Cell-Derived Intestinal Epithelial Cells

Viruses, 2023
Sapoviruses, like noroviruses, are single-stranded positive-sense RNA viruses classified in the family Caliciviridae and are recognized as a causative pathogen of diarrhea in infants and the elderly. Like human norovirus, human sapovirus (HuSaV) has long

Sapovirus in Water, Japan

Emerging Infectious Diseases, 2007
Sapoviruses are etiologic agents of human gastroenteritis. We detected sapovirus in untreated wastewater, treated wastewater, and a river in Japan. A total of 7 of 69 water samples were positive by reverse transcription-PCR. Phylogenetic analysis of the viral capsid gene grouped these strains into 4 genetic clusters.
