Glycyrrhiza polysaccharides inhibits PRRSV replication

Virology Journal, 2023
AbstractGlycyrrhiza polysaccharide (GCP) is a natural plant active polysaccharide extracted from traditional Chinese medicine licorice. In this research, we studied the antiviral activity of glycyrrhiza polysaccharide against porcine reproductive and respiratory syndrome virus (PRRSV), a virus of the Arteriviridae family, with a high rate of variation ...

Restriction fragment length polymorphism of ORF6 and ORF7 genes of porcine reproductive and respiratory syndrome virus (PRRSV) vaccine strains registered in the Czech Republic

Veterinární Medicína, 2006
Restriction fragment length polymorphism (RFLP) of open reading frames 6 and 7 was applied to comparative genetic analysis of live attenuated vaccine strains (Amervac-PRRS/A3, Porcilis PRRS, Ingelvac PRRS) of porcine reproductive and respiratory syndrome

Risk Factors and Spatial-Temporal Analysis of Porcine Reproductive and Respiratory Syndrome Seroprevalence in China Before and After African Swine Fever Outbreak

Frontiers in Veterinary Science, 2022
Porcine reproductive and respiratory syndrome (PRRS) is an infectious viral disease that causes great harm to the pig industry. PRRS virus (PRRSV), the causative agent of PRRS, is characterized by severe reproductive failure and respiratory confusion ...

Evaluation of PRRSV vaccine efficacy following infection with PRRSV 1-7-4

Journal of Swine Health and Production, 2021
Our objective was to evaluate whether porcine reproductive and respiratory syndrome virus (PRRSV) vaccination improved mortality and morbidity following experimental infection with a PRRSV restriction fragment length polymorphism 1-7-4. Results indicated that mortality and morbidity were significantly lower for vaccinated pigs as compared to ...

Differentiation of porcine reproductive and respiratory syndrome virus European vaccine strains from Czech field isolates by restriction fragment length polymorphism analysis of ORF5 gene

Veterinární Medicína, 2002
Restriction fragment length polymorphism (RFLP) analysis of open reading frame 5 was developed for typing of Czech strains of porcine reproductive and respiratory syndrome virus (PRRSV). The set of restriction enzymes Acc I, Hae II and SnaB I allowed the

The Innate Immune DNA Sensing cGAS-STING Signaling Pathway Mediates Anti-PRRSV Function

Viruses, 2021
Porcine reproductive and respiratory syndrome virus (PRRSV) modulates host innate immunity which plays a key role against PRRSV infection. As a RNA virus, PRRSV is mainly sensed by innate immune RNA receptors, whereas the role of innate immune DNA ...

Analysis of Swine Conventional Dendritic Cells, DEC205⁺CD172a^+/−CADM1⁺, from Blood and Spleen in Response to PRRSV and PEDV

Viruses, 2019
Conventional dendritic cells (cDCs) cannot be infected by porcine reproductive and respiratory syndrome virus (PRRSV) but respond to infection via cytokine production, indicating a possible role in initiation/regulation of the immune response against ...

Integration of Transcriptome and Proteome in Lymph Nodes Reveal the Different Immune Responses to PRRSV Between PRRSV-Resistant Tongcheng Pigs and PRRSV-Susceptible Large White Pigs [PDF]

Frontiers in Genetics, 2022
Porcine reproductive and respiratory syndrome (PRRS) is an infectious disease that seriously affects the swine industry worldwide. Understanding the interaction between the host immune response and PRRS virus (PRRSV) can provide insight into the PRRSV pathogenesis, as well as potential clues to control PRRSV infection.
