articles about PRRS in Abstracts

PRRS virus persistence in processing fluids was not affected by the sow parity effect in most of the breeding herds studied.

For this trial, dry disinfectant was the most efficacious in reducing the viral RNA on both boots and subsequent surfaces.

This study demonstrated the presence of multiple PRRSV lineages, sub-lineages, and variants in swine herds and its potential association with swine reproductive performance under field conditions.

Viral pathogens of pigs can survive in representative volumes of feed and feed ingredients during long-distance commercial transport across the continental United States.

Sequencing results suggest that this represents the emergence of a new variant within Lineage 1C distinct from what has been previously circulating.

Selection for antibody response to PRRSV can increase litter size in purebred and commercial sows.

An evaluation and comparison of which specimen type: testicles, tails or udder wipes had the highest sensitivity at determining the litter PRRSv status compared to serum.

A study on the heterologous protection between Japanese Type 1 and Type 2 PRRSV isolates.

The methods derived from this study open up avenues to further investigate airborne transmission and risk of virus introduction into farms contributing to the control of diseases in swine.

A compound was identified that blocks the interaction between PRRSV and CD163, a macrophage-specific membrane scavenger receptor, potentially preventing infection.

Sampling technique validated to monitor PRRSV-2 using serosanguinous exudate or processing fluids (PFs) from tissues obtained during tail docking and castration provides a general framework to interpret PRRSV-2 surveillance program results more accurately.

The aim of this work was to compare the profile and time-course of humoral and cell-mediated immunity in stable and unstable herds, respectively.

Processing fluids (PF) constitute a useful sample to detect PRRSV infections at processing. Current practice to bleed 30 pigs could be underestimating PRRSV prevalence in the herd.

In a PRRSV-endemic setting involving bacterial co-infections, an ABF production strategy may leave pigs at considerable risk of exposure to severe clinical disease.

Under current biosecurity practices, a substantial risk exists for the spread of PRRS virus due to truck sharing.

The efficacy of the attenuated PRRSV-1 vaccine in 1-day-old pigs seropositive to PRRSV prior to a PRRSV-1 challenge was demonstrated by improvement of clinical, virological and immunological variables.
