Abstract

Porcine reproductive and respiratory syndrome virus (PRRSV) is a devastating virus which suppresses the expression of type I and II interferons (IFNs) as well as several pro-inflammatory cytokines. Our previous study reported that saponin quil A had a potential to up-regulate the expression of type ...

Abstract

The objective of this study was to compare the efficacy of a commercial porcine reproductive and respiratory syndrome (PRRS) subunit vaccine and a prototype PRRS II subunit vaccine against a highly pathogenic PRRS virus (HP-PRRSV) in pigs. Both vaccines were administered intramuscularly in 2 doses...

Abstract

China is rich in native pig breeds, yet information regarding the susceptibility/resistance of local breeds to porcine reproductive and respiratory syndrome virus (PRRSV) infection is lacking. In the present study, an in vitro method based on assessing PRRSV replication in porcine alveolar...

Abstract

Biosecurity is defined as the set of practices carried out to prevent the introduction and spread of infectious agents in a herd. These practices are essential in swine production, especially for highly infectious agents such as porcine reproductive and respiratory syndrome virus (PRRSv). Even with ...

Abstract

PRRS is one of the main viral diseases in pig production, causing huge economic losses to the swine industry worldwide. The virus shows an intrinsic genomic instability and is able to change continuously, with the emergence of new strains, with different pathogenicity patterns. Commercially...

Abstract

Porcine reproductive and respiratory syndrome (PRRS) has caused significant economic losses to the pig industry worldwide over the last 30 years. GP4 is a minor highly glycosylated structural protein composed of 187 and 183 amino acids in types I and II porcine reproductive and respiratory syndrome ...

Abstract

The efficacy of the CA-2-MP120 vaccine, a cell culture-attenuated strain of virulent porcine reproductive and respiratory syndrome virus (PRRSV), was assessed in pigs. Despite the persistence of viremia in all vaccinated animals during the immunization period, the virus was not detected in...

Abstract

The objective of this study was to prepare transfer factor (TF) from the spleen of pig immunized with porcine reproductive and respiratory syndrome (PRRS) attenuated-live virus vaccine, then detect its immune activities and expect to provide a scientific basis for developing a new immunopotentiator ...

Abstract

Modified live vaccine (MLV) based on highly pathogenic porcine reproductive and respiratory syndrome virus (HP-PRRSV) is prone to quick reversion of virulence upon circulating in host animals. The objective of this study was to evaluate the virulence reversion potential of HP-PRRSV MLV and to...
