Porcine epidemic diarrhea (PED), caused by porcine epidemic diarrhea virus (PEDV) infection, leads to significant economic losses in the swine industry worldwide. In our studies, we found that glycyrrhizin, the major component of licorice root extracts, could moderately inhibit PEDV infection in Vero cells, when analyzed by western blot, qRT-PCR and a plaque formation assay. We also revealed that glycyrrhizin inhibited the entry and replication of PEDV. In addition, we demonstrated that glycyrrhizin decreased the mRNA levels of proinflammatory cytokines. Since glycyrrhizin is a competitive inhibitor of high mobility group box-1 (HMGB1), we confirmed that TLR4 and RAGE (£ associated with PEDV pathogenesis during the infection in Vero cells. In summary, our studies provide a molecular basis for developing novel therapeutic methods to control PEDV infection, based on glycyrrhizin and its derivatives.

To bolster the capacity for managing potential infectious diseases in the future, it is critical to develop specific antiviral drugs that can be rapidly designed and delivered precisely. Herein, a CRISPR/Cas13d system for broad-spectrum targeting of influenza A virus (IAV) from human, avian, and swine sources is designed, incorporating Cas13d mRNA and a tandem CRISPR RNA (crRNA) specific for the highly conserved regions of viral polymerase acidic (PA), nucleoprotein (NP), and matrix (M) gene segments, respectively. Given that the virus targets cells with specific receptors but is not limited to a single organ, a Susceptible Cell Selective Delivery (SCSD) system is developed by modifying a lipid nanoparticle with a peptide mimicking the function of the hemagglutinin of influenza virus to target sialic acid receptors.

Background: Neospora caninum (Apicomplexa, Sarcocystidae) is a protozoan parasite regarded as a major cause of reproductive failure in cattle. Swine are susceptible to N. caninum infection; however, the role of these animals in the circulation, maintenance, and transmission of N.

Piglets afflicted with porcine epidemic diarrhea virus (PEDV) experience severe diarrhea and elevated death rates, leading to substantial financial losses in the pig farming sector. The objective of this study is to investigate the impact of saponins on PEDV within Vero cells by utilizing different methodologies to evaluate their anti-PEDV effect. By producing 40 saponins, we have discovered that No.

Dental anomalies are frequent in boars and pigs, and they generally affect the first premolar loci. The prevalence of these dental anomalies was investigated in a large number of populations around the world. These studies mainly focused on the influence of domestication, size, sexual dimorphism or food hardness on these anomalies.

Swine acute diarrhea syndrome coronavirus (SADS-CoV) is a novel porcine coronavirus that was recently identified in southern China in 2017. At present, there is a lack of nationwide epidemiological investigations of the newly emerged SADS-CoV. Because Vietnam is geographically adjacent to southern China, many diseases have spread from China to Vietnam.
