Actinobacillus pleuropneumoniae possesses an antiviral activity against PRRSv
A pre-infection of SJPL and PAM cells with App blocked completely PRRSV infection.

Discovered a new gene expression mechanism in porcine reproductive and respiratory syndrome
These studies demonstrate for the first time, to our knowledge, that a protein can function as a transactivator of ribosomal frameshifting.
In vitro and ex vivo analyses of co-infections with SIV and PRRSv
This study is the first to show an impact of PRRSV/SIV co-infection and superinfections in the cellular and tissue immune response at the molecular level.
Recombination of PRRS viruses may produce mosaic isolates
Analysis of ORF5 and full-length genome sequences of PRRSV isolates of genotypes 1 and 2 retrieved worldwide provides evidences supporting that recombination is a common phenomenon and may produce mosaic isolates.
Impact of PRRS vaccination timing in pigs with different maternal immunity levels
The main objective of this study was to further investigate this issue and determine if vaccination of older pigs would induce an earlier viremia and seroconversion.
Comparison of the virulence of European and North American genotypes of porcine reproductive and respiratory syndrome virus in experimentally infected pigs
This study demonstrates that type 2 PRRSV is more virulent than type 1 PRRSV in this experimental setting.
Effect of sample collection material on the detection of PRRSV in oral fluid
Cotton rope provided the best overall diagnostic performance.
An intact sialoadhesin (Sn/SIGLEC1/CD169) is not required for attachment/internalization of the porcine reproductive and respiratory syndrome virus (PRRSV)
The results demonstrate that the expression of the SIGLEC1 gene is not required for infection of pigs with PRRSV and the absence of SIGLEC1 does not contribute to the pathogenesis of acute disease.
Assessment of the economic impact of PRRS virus on United States pork producers
Despite over 25 years of experience and research, porcine reproductive and respiratory syndrome remains a costly disease of pigs in the United States.
Impact of genetic variation and geographic distribution of PRRSV on infectivity and pig growth
The PRRSV genetic variability which is determined by a local and temporal evolution at the farm level could be considered in a perspective of prevention.
Characterization of homologous and heterologous adaptive immune responses in porcine reproductive and respiratory syndrome virus infection
The present study characterized the homologous and heterologous immune response in type-I porcine reproductive and respiratory syndrome virus (PRRSV) infection.
Emergency vaccination alleviates highly pathogenic porcine reproductive and respiratory syndrome virus infection after contact exposure
These results indicated that emergency vaccination could effectively alleviate HPPRRSV infection during experimental contact exposure.
Mannan oligosaccharide modulates the immune responses in weanling pigs
Feeding mannan oligosaccharide may activate immunity against PRRSV.
Poor weaning transition ADG in is not correlated with pathological or immunological markers of enteric disease during a PRRSV outbreak
Poor tADG in pigs is not correlated with pathogens or immunological markers of enteric disease during a PRRSV.
Gilt replacement strategies used in two swine production areas in Quebec in regard to PRRSv
Replacement strategies may have weaknesses that should be addressed to facilitate PRRSV management at the herd and regional levels.
Regional PRRS control with an autogenous vaccination strategy
Regional vaccination with an autogenous killed vaccine did not effectively reduce the number of PRRSV related crises in the vaccinated farms.
