Objective: To increase the recombinant adenovirus vector mediated human rotavirus VP6 gene expression through coden optimization.
Methods: We have artificially synthesized VP6 gene of group A human rotavirus according to the human biased codon. The modified gene was transfected into 293 cells using adenovirus vector and the gene product, the respective protein was produced. The expression level of optimized gene and wild type gene was detected by Immunofluorescence (IF) and Western Blot.
Result: A remarkable increase of the expression level of optimized VP6 gene in comparison with the wild-type control.
Conclusion: The coden optimization indeed help increasing the recombinant adenovirus mediated human rotavirus gene expression, which indicated the potential application of such recombinant adenoviruses in the development of adenoviral-vectored rotavirus vaccines.

Probiotics have shown efficacy in preventing and reducing infections caused by common viruses, including rotavirus, norovirus, hepatitis, human papillomavirus (HPV), human immunodeficiency virus (HIV), and herpes simplex virus (HSV). A randomized, double-blind, placebo-controlled, three-arm parallel-group study was conducted on 56 patients with moderate COVID-19 symptoms. Patients were randomly assigned to one of the three groups: standard treatment combined with UBBC-07, standard treatment combined with Unique IS-2, or standard treatment with a placebo.

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.

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.

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
