Sapoviruses are increasingly being recognized as pathogens associated with gastroenteritis in humans. Human sapoviruses are currently assigned to 18 genotypes (GI.1-7, GII.1-8, GIV.1, and GV.1-2) based on the sequence of the region encoding the major structural protein. In this study, we evaluated 11 polymerase chain reaction (PCR) assays using published and newly designed/modified primers and showed that four PCR assays with different primer combinations amplified all of the tested human sapovirus genotypes using either synthetic DNA or cDNA prepared from human sapovirus-positive fecal specimens. These assays can be used as improved broadly reactive screening tests or as tools for molecular characterization of human sapoviruses.

A Metagenomic Survey of Virological Hazards in Market-Ready Oysters.

Food Environ Virol

January 2025

Wageningen Food Safety Research, Akkermaalsbos 2, 6708 WB, Wageningen, the Netherlands.

Viral contamination of bivalve molluscs, such as oysters, is a well-recognized food safety risk. The aim of this study was to assess virological hazards in market-ready oysters on the Dutch market. Non-targeted metagenome analysis was first performed on norovirus spiked-in samples showing linear and sensitive detection of norovirus GI.

In the current study, the analytical sensitivity, analytical specificity, reproducibility, anti-interferences ability, and clinical performance of the QIAstat-Dx Gastrointestinal Panel (GIP) system were evaluated using pooled stool samples. Results showed that the pooled sample test detected the selected ten targets exclusively, with no cross reaction with any other targets of common enteropathogens. The analytical sensitivity of the pooled sample test on QIAstat-Dx GIP system was 10 CFU/ml for Shigella spp.

Article Synopsis
  • A study analyzed 1,625 stool samples from children with diarrhea in Japan over four years (2018-2022) to detect human astroviruses (HAstVs) and other diarrheal viruses, finding HAstV in 8.6% of samples.
  • The prevalence of HAstVs varied by year, with a notable increase to 20.1% in 2021-2022, and a significant infection rate was observed in children aged 1-3 years.
  • The study identified multiple HAstV genotypes, including outbreaks of HAstV1 and MLB2 during the COVID-19 pandemic, and noted for the first time a mixed infection of HAstV1 and MLB1.

A dual typing system establishment and global diversity analysis for sapoviruses.

BMC Genomics

November 2024

College of Life Sciences and Bioengineering, Beijing Jiaotong University, Beijing, 100044, China.

Article Synopsis
  • - The study focuses on refining the classification of sapoviruses, a diverse group of viruses causing gastroenteritis in humans and animals, by optimizing the criteria for their genogroups and genotypes due to an increase in identified sequences.
  • - Using genetic distance analysis, researchers updated the classification thresholds, expanding VP1 genogroups to thirty-four and identifying twenty-four RdRp P-groups, leading to the addition of a new genotype for human sapoviruses.
  • - The findings established a dual typing system for sapoviruses based on both VP1 and RdRp sequences, although no specific distribution pattern for human sapoviruses was detected during the analysis.

Background: While diarrhoeal disease remains a leading cause of death in children aged <5 years in low- and middle-income countries (LMICs), it also poses significant health risks for older children, underscoring the importance of our study focusing on children aged <10 years. In this systematic review, we assessed common diarrhoea aetiologies in children aged <10 years in LMICs.

Methods: We identified relevant articles in PubMed, Embase, and Web of Science using pre-defined search criteria.
