Background: The RNA genome of hepatitis C virus (HCV) displays extensive sequence variation. In this study, serotyping and genotyping techniques were applied to assess this variability by comparing the performance of the serotyping assay with a panel of well-characterized HCV strains isolated from chronic active hepatitis (CAH) patients.
Patients And Methods: 60 serum samples from CAH patients were analyzed. All isolates were genotyped by a line probe assay and the results of genotyping and serotyping were evaluated.
Results: The overall sensitivity of the serotyping and genotyping techniques was 81.16% with a concordance of 73.3%. Type 4 was detected in 73.3% of cases and it was highly heterogeneous.
Conclusion: Type 4 HCV is the most prevalent type in Egyptian CAH patients and there is a high concordance between the results of serotyping and genotyping techniques.

Respiratory disease (RD) is a worldwide leading threat to the pig industry, but there is still limited understanding of the pathogens associated with swine RD. In this study, we conducted a nationwide genomic surveillance on identifying viruses, bacteria, and antimicrobial resistance genes (ARGs) from the lungs of pigs with RD in China. By performing metatranscriptomic sequencing combined with metagenomic sequencing, we identified 21 viral species belonging to 12 viral families.

The accessibility of genetic data will facilitate a more comprehensive delineation of FMDV phylogeny on a global scale. In this study, we investigated the FMDV strains circulating in Russia during the 2013-2014 period in geographically distant regions utilizing whole genome sequencing followed by maximum-likelihood phylogenetic reconstruction of whole genome and VP1 gene sequences.

The global incidence of serovar Schwarzengrund has risen in recent years. This serotype has been isolated from poultry, retail meat, and other food products, leading to multiple outbreaks. Alongside the increase in infections, there are growing concerns about the increasing levels of antimicrobial resistance (AMR) among Schwarzengrund strains.

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.

Purpose: Dengue virus, a major global health concern, exhibits significant genetic diversity, leading to distinct serotypes and genotypes. Dengue is the second most common disease spread by mosquitoes that infect humans, after malaria. In recent decades, there has also been a shift in the tendencies of virus transmission from urban to peri-urban and rural settings.
