PRRS virus elimination: How to prove herd negativity?
One of the challenges when conducting a disease elimination project is to ensure that the pathogen has in deed been eliminated from the herd.
Genomics and pig health
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.
Ohio State researcher develops innovative vaccine for profit-draining swine virus
The new vaccine is also enclosed in biodegradable nanoparticles, which improves its efficacy and its absorption by a pig's immune system.
Vaccination against PRRSV: a practical approach
In general terms, immunization through vaccination is the easiest and safest way to stabilize a herd.
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.
PRRSV: Interaction with other respiratory pathogens
PRRSV by itself may induce mild-to-severe respiratory disease but rarely results in mortality.
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.
PRRS Immunology
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.
New Zealand: Supreme Court blocks imports of consumer-ready cuts of raw pork
The Supreme Court has issued an order blocking imports of consumer-ready cuts of raw pork until it hears an appeal from the Pork Industry Board.
Clinical case: PRRSV and PCV2 interaction in a farm
One month after the beginning of the outbreak of reproductive failure in sows, acute respiratory disorder and diarrhoea that was non-responsive to antibiotics started in weaned pigs aged 6-8 weeks...
India: PRRS affects pigs in Mizoram
Samples of dead and sick pigs were sent to the ICAR Research Complex where it was found that some of the pigs were infected with PRRS.
More articles on PRRS
We resume the section on PRRS (a disease that entails costs of 664 million dollars per year) with new authors and subjects, or updating subjects that we have already dealt with.
The cost of PRRS to pork producers
The total cost of productivity losses to US producers is estimated at US$664 million annually but productivity losses are shifting from the growing pig herd to the sow herd.
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.
