AI Article Synopsis

  • Between July 2009 and June 2011, rotavirus was found in 507 episodes of gastroenteritis in children under 3 years old in Gipuzkoa, Spain, with G-type determined in 90.3% of cases.
  • During the 2010-2011 winter epidemic, G12 rotavirus became dominant, accounting for 65% of the cases, and showed a widespread impact across both rural and urban areas.
  • The hospitalization rate for G12-infected children was significant, particularly in those under 2 years old, indicating that G12 may become a major rotavirus genotype in the future.

Article Abstract

Between July 2009 and June 2011, rotavirus was detected in 507 of 4597 episodes of acute gastroenteritis in children aged <3 years in Gipuzkoa (Basque Country, Spain), of which the G-type was determined in 458 (90·3%). During the annual seasonal epidemic of 2010-2011, the unusual G-type 12 was predominant, causing 65% (145/223) of cases of rotavirus gastroenteritis. All the G12 strains were clustered in lineage III and were preferentially associated with P-type 8. This epidemic was characterized by broad geographical distribution (rural and urban) and, over 7 months, affected both infants and children, the most frequently affected being children between 4 and 24 months. Of children with rotavirus G12, 16% required hospital admission, the admission rate in children aged <2 years being 20·7 cases/10 000 children. The sudden emergence and predominance of G12 rotaviruses documented in this winter outbreak suggest that they may soon become a major human rotavirus genotype.

Rotavirus A (RVA) is the primary enteric pathogen of humans and many other species. However, RVA interspecies transmission remains poorly understood. In this study, we conducted a comprehensive screening and genotyping analysis of RVA in 1706 wild animal samples collected from various regions within Yunnan Province, China.

Genome Characterization of Mammalian Orthoreovirus and Porcine Epidemic Diarrhea Virus Isolated from the Same Fattening Pig.

Department of Preventive Veterinary Medicine, College of Veterinary Medicine, Northwest A&F University, Yangling 712100, China.

In 2020, severe diarrhea occurred in four-month-old fattening pigs from nine farms in Shandong Province, China. Fecal samples were collected from diseased pigs and tested by PCR for the presence of mammalian orthoreovirus (MRV), porcine epidemic diarrhea virus (PEDV), porcine deltacoronavirus (PDCoV), porcine rotavirus A (PoRVA), transmissible gastroenteritis virus (TGEV), porcine kobuvirus (PKV), and pseudorabies virus (PRV). The viral RNA of MRV and PEDV was detected in the fecal samples.

Background: Rotavirus (RV) and Adenovirus (AdV) gastroenteritis affect children worldwide. The sensitivity and specificity of the AMP Rapid Test ROTA/ADENOVIRUS [AMP-RA] for the detection of RV and AdV were compared against qPCR Allplex™ GI-Virus Assay [Allplex-GI].

Methods: A cross-sectional hospital-based surveillance study was conducted using stool samples from 1,148 patients under the age of five years between July 2023 and May 2024 with gastroenteritis.

Article Synopsis
  • The study focused on the prevalence of various viruses causing acute gastroenteritis (AGE) in children under five years old in Yunnan, China.
  • Over 610 stool samples were analyzed, revealing that rotavirus (RVA) was present in nearly 29% of the cases, with G8P[8] emerging as the dominant genotype in 2022.
  • Norovirus was detected in about 12% of the samples, with GII.4 being the most common strain, while other viruses like sapovirus and human adenovirus had lower positivity rates.
  • The results indicated higher AGE incidence in male children, particularly among those aged 12-23 months, with infection rates peaking in the early months of the year, highlighting

A single residue switch mediates the broad neutralization of Rotaviruses.

Broadly neutralizing antibodies (bNAbs) could offer escape-tolerant and lasting protection against viral infections and therefore guide development of broad-spectrum vaccines. The increasing challenge posed by viral evolution and immune evasion intensifies the importance of the discovery of bNAbs and their underlying neutralization mechanism. Here, focusing on the pivotal viral protein VP4 of rotavirus (RV), we identify a potent bNAb, 7H13, exhibiting broad-spectrum neutralization across diverse RV genotypes and demonstrating strong prevention of virus infection in female mice.
