Is the right strategy to get a farm stable, that is, control clinical signs reducing the economic impact of the disease; or should a farm adopt strategies to go “negative”? As for other questions in the epidemiological field, our answer is “it depends”.

One of the challenges when conducting a disease elimination project is to ensure that the pathogen has in deed been eliminated from the herd.

One of the greatest long-term potentials for genomic selection is to identify specific genes or genomic regions with a significant impact on pig health and to aid selection for disease resistance and/or disease tolerance.

In general terms, immunization through vaccination is the easiest and safest way to stabilize a herd.

PRRSV by itself may induce mild-to-severe respiratory disease but rarely results in mortality.

Resolving the basis of viral and host variation will require identification and characterization of key B- and T-cell epitopes conserved among diverse PRRSV, and of the molecular and structural details of key effector antibodies, T-cell antigen receptors, and MHC molecules that mediate broad, cross-protective immunity.
