Immunity to PRRSV: Double-edged sword

Veterinary Microbiology, 1997
The immune system is a double-edged sword for porcine reproductive and respiratory syndrome virus (PRRSV) infection. On one edge PRRSV has a predilection for immune cells and the disease manifestations can be linked directly to changes in the immune system.

Development of a novel duplex crystal digital PCR for the detection of PRRSV–1 and PRRSV–2

Frontiers in Cellular and Infection Microbiology
Background Porcine reproductive and respiratory syndrome (PRRS) is a widely prevalent disease of reproductive failure of pregnant pigs and respiratory syndromes in pigs of different ages, especially in piglets.

Use of Three Air Samplers for the Detection of PRRSV-1 under Experimental and Field Conditions

, 2018
Airborne transmission of porcine reproductive and respiratory syndrome virus (PRRSV) has been known for a long time. Most experiments were performed using PRRSV-2 strains and fairly little information is available on the airborne spread of PRRSV-1.

Impact of a killed PRRSV vaccine on sow longevity in a PRRSV infected swine herd

Journal of Applied Animal Research, 2012
In porcine reproductive and respiratory syndrome virus (PRRSV)-infected farms, there is an increase in the female culling rate, mainly due to reproductive problems and culling of young females. This has significant economic importance, as the low female culling rate is an important management factor.

Two nanobody-based immunoassays to differentiate antibodies against genotype 1 and 2 porcine reproductive and respiratory syndrome virus

Animal Diseases
Porcine reproductive and respiratory syndrome virus (PRRSV) infection causes significant economic loss to the global pig industry. Genotype 1 and 2 PRRSV (PRRSV-1 and -2) infections have been reported in China, Europe and America. For accurate prevention,

Micro-dissecting the pathogenesis and immune response of PRRSV infection paves the way for more efficient PRRSV vaccines

, 2012
Porcine reproductive and respiratory syndrome virus (PRRSV) is the most important infectious pathogen in pigs worldwide nowadays. Due to its genetic drift and increasing power to escape from immunity, PRRSV becomes more and more difficult to control ...
