Efficacy of Type 2 PRRSV vaccine against Chinese and Vietnamese HP-PRRSV challenge in pigs

Vaccine, 2014
Porcine reproductive and respiratory syndrome virus (PRRSV) causes significant reproductive losses in the sow herd and respiratory disease in growing pigs. The virus belongs to the family Arteriviridae and there are two major genotypes. Type 1 is represented by Lelystad virus, the European prototype virus, and Type 2 is represented by the North ...

Packaged Heteroclite Subgenomic RNAs of PRRSV

2001
Porcine reproductive and respiratory syndrome virus (PRRSV) is a member of the Arteriviridae family of the Nidovirales (Meulenberg et al, 1993b; Nelsen et al., 1999). While the complete genomes of three PRRSV strains are known (Allende et al., 1999; Meulenberg et al., 1993; Nelsen et al., 1999), main questions remains to be elucidated concerning viral ...

The mRNA vaccine expressing fused structural protein of PRRSV protects piglets against PRRSV challenge

Veterinary Microbiology
The swine industry experiences substantial economic losses annually due to the porcine reproductive and respiratory syndrome virus (PRRSV). The limited protective efficacy of existing commercial vaccines against epidemic PRRSV underscores the urgent need for innovative solutions.

Commercial porcine reproductive and respiratory syndrome virus (PRRSV)‐2 modified live virus vaccine against heterologous single and dual Korean PRRSV‐1 and PRRSV‐2 challenge

Veterinary Record, 2018
This study evaluated porcine reproductive and respiratory syndrome virus (PRRSV)‐2 modified live virus (MLV) vaccine against heterologous single and dual challenge of Korean PRRSV‐1 and PRRSV‐2. Pigs were administered PRRSV‐2 MLV vaccine intramuscularly at 21 days of age and inoculated intranasally with both genotypes at 56 days of age.

Development of blocking ELISA for detection anti-PRRSV antibodies and serological investigation of PRRSV in China

International Journal of Biological Macromolecules
Porcine reproductive and respiratory syndrome virus (PRRSV) demonstrates a significantly high prevalence among swine populations. Monoclonal antibodies (mAbs) with high affinity for conserved epitopes of PRRSV can facilitate the development of a broad-spectrum detection method for this virus.

Nucleic acids encoding TGEV and PRRSV sequences for improved expression of PRRSV sequences

2011
The present invention relates to nucleic acids comprising: (a) sequences of a replication competent transmissible gastroenteritis virus (TGEV), which sequences encode a TGEV replicase under the control of expression regulatory sequences, wherein the replicase is expressed in a host cell and will initiate replication of the nucleic acid and thus ...

Comparison of 4 commercial modified-live porcine reproductive and respiratory syndrome virus (PRRSV) vaccines against heterologous Korean PRRSV-1 and PRRSV-2 challenge.

Canadian journal of veterinary research = Revue canadienne de recherche veterinaire, 2019
The efficacy of 4 commercial porcine reproductive and respiratory syndrome virus (PRRSV) modified-live vaccines (MLV), against PRRSV-1 and PRRSV-2 was evaluated and compared in growing pigs. Two of the vaccines were based on PRRSV-1 and two on PRRSV-2. There were no significant differences between each of the two PRRSV-1 MLV vaccines and the two PRRSV ...
