Sapovirus as an Emerging Pathogen Implicated in Chronic Diarrhea in Post-Solid Organ Transplant Setting: A Brief Report

JOURNAL OF GASTROINTESTINAL INFECTIONS
Background Diarrhea is common in the post-solid organ transplant setting and can be infectious or noninfectious in origin. Among infectious causes of diarrhea norovirus and Clostridioides difficle have been implicated commonly while mycophenolate mofetil

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 ...

Investigation of removal and inactivation efficiencies of human sapovirus in drinking water treatment processes by applying an in vitro cell-culture system.

Water Research, 2023
Here, we examined the efficiencies of drinking water treatment processes for the removal and inactivation of human sapovirus (HuSaV). We applied a recently developed in vitro cell-culture system to produce purified solutions of HuSaV containing virus ...

Molecular epidemiology of human sapovirus based on the surveillance of wastewater and patients with acute gastroenteritis in Osaka, Japan.

Science of the Total Environment
Wastewater-based epidemiology has recently emerged as a promising tool for determining the prevalence of infectious diseases in a community. In the present study, human sapoviruses (HuSaVs) detected in wastewater collected weekly from January 2023 to ...

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

PreK-12 school and citywide wastewater monitoring of the enteric viruses astrovirus, rotavirus, and sapovirus.

Science of the Total Environment
Wastewater monitoring is an efficient and effective way to surveil for various pathogens in communities. This is especially beneficial in areas of high transmission, such as preK-12 schools, where infections may otherwise go unreported.

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

Epidemiology and molecular evolution of GI.1 sapovirus in the recent era

Journal of Medical Virology
Sapovirus (SaV) infection is increasing worldwide. Herein, we provided evidence of a significant increase in SaV infection in Japan during 2010–2022, primarily due to the considerable (p = 0.0003) rise of the GI.1 genotype. Furthermore, we found that all
