Activated sludge and UV-C254 for Sapovirus, Aichivirus, Astrovirus, and Adenovirus processing

International Journal of Environmental Health Research, 2023
In this study, the detection rates of four enteric viruses, Human Astrovirus (HAstVs), Aichivirus (AiVs), Human Adenovirus (HAdVs), and Sapovirus (SaVs) are carried out to assess the virological quality of the treated wastewater.

Application Research on the Triplex RT-ddPCR Assay for the Simultaneous Detection of Human Astrovirus and Sapovirus in Bivalve Shellfish.

Foodborne pathogens and disease
Human astrovirus (HAstV) and sapovirus (SaV) are significant pathogens associated with acute gastroenteritis in humans. This study established a triple reverse transcription-droplet digital polymerase chain reaction (PCR) (RT-ddPCR) assay incorporating ...

First report of coinfection and whole‐genome sequencing of norovirus and sapovirus in an acute gastroenteritis patient from Pakistan

Journal of Medical Virology, 2023
Acute gastroenteritis is one of the most common diseases in infants and children in developing countries including Pakistan. In Pakistan, rotavirus (RVA) is known to contribute significantly to pediatric diarrheal illness, but the contribution of other ...

Sapovirus-like particles derived from polyprotein

Virus Research, 2008
We 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 ...

Genotypic Analysis and Clinical Findings of Sapovirus‐Associated Acute Gastroenteritis in Mie Prefecture, Japan, 2010–2022

Journal of Medical Virology
Sapovirus (SaV) is one of the major viruses causing acute gastroenteritis. Of the 1981 fecal specimens collected through sentinel pediatric acute gastroenteritis pathogen surveillance in Mie Prefecture, Japan (2010–2022), 236 were positive for SaV ...

Norovirus and sapovirus infections after allogeneic hematopoietic stem cell transplantation: is it worth it to look for them?

Leukemia and Lymphoma, 2023
Norovirus (NoV) and Sapovirus (SaV) are potential causative agents of diarrhea after allogeneic HSCT but little is known in this population. We performed a retrospective analysis by RT-PCR of calicivirus (NoV and SaV), Human adenovirus (HAdV), rotavirus (

Intrahost viral evolution during chronic sapovirus infections

Journal of Clinical Virology, 2019
Sapovirus 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, 2006
Sapovirus (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, 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 ...

Development of a Quadruplex RT-qPCR for the Detection of Porcine Astrovirus, Porcine Sapovirus, Porcine Norovirus, and Porcine Rotavirus A

Pathogens
Porcine astrovirus (PoAstV), porcine sapovirus (PoSaV), porcine norovirus (PoNoV), and porcine rotavirus A (PoRVA) are newly discovered important porcine diarrhea viruses with a wide range of hosts and zoonotic potential, and their co-infections are ...
