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.

Characterization of homologous and heterologous adaptive immune responses in porcine reproductive and respiratory syndrome virus infection
The present study characterized the homologous and heterologous immune response in type-I porcine reproductive and respiratory syndrome virus (PRRSV) infection.

NewsA new methodology to produce a vaccine for foot-and-mouth disease
The vaccine is all synthetic, made up of tiny protein shells designed to trigger optimum immune response.
United States donates one million doses of Classical Swine Fever vaccine to Guatemala
On March 19, APHIS donated the vaccines based on a request for assistance from the Guatemalan Chief Veterinary Officer, Dr. Humberto Maldonado, to help Guatemala control the spread of CSF there.
Protective effect of the maternally derived porcine circovirus type 2 (PCV2)-specific cellular immune response in piglets by dam vaccination against PCV2 challenge
Maternally derived adaptive cellular immune responses play a critical role in protecting newborn piglets challenging PCV2 at 3 weeks of age.
Emergency vaccination alleviates highly pathogenic porcine reproductive and respiratory syndrome virus infection after contact exposure
These results indicated that emergency vaccination could effectively alleviate HPPRRSV infection during experimental contact exposure.
Preventing disease: One billion pigs vaccinated with Ingelvac CircoFLEX®
Veterinarians and farmers across the globe have reached the landmark of protecting one billion pigs from the potentially devastating effects of Porcine Circovirus Disease (PCVD) using Ingelvac CircoFLEX®
New edema vaccine licensed in Switzerland
Ecoporc Shiga induces a high level of immunity against shigatoxin, produced by E coli bacteria which cause edema.
Effect of sow and piglet porcine circovirus type 2 (PCV2) vaccination on piglet mortality, viraemia, antibody titre and production parameters
PCV2 vaccination was able to overcome this interference since the ADWG was improved.
It’s not too late to get a flu vaccination
As flu season swings into full gear, producers and those who work with pigs are reminded that it’s not too late to get a seasonal flu vaccination.
Harrisvaccines to develop FMD vaccine
The U.S. Department of Homeland Security has awarded Harrisvaccines a $1 million-plus contract to develop a vaccine for foot-and-mouth disease, one of the world’s most economically devastating animal diseases.
Effect of the viraemia due to the porcine circovirus type 2 (PCV2) on production parameters
The most effective way of avoiding the production losses associated with the PCV2 consists in avoiding the appearance of the viraemia by inducing a passive or an active immunity that minimizes the circulation of the virus in the farm.
Oral immunization of weaned piglets with tobacco seeds expressing antigenic proteins of VTEC
Oral administration of recombinant tobacco seeds expressing antigenic proteins against VTEC strains can induce an increase of mucosal antibodies.
Regional PRRS control with an autogenous vaccination strategy
Regional vaccination with an autogenous killed vaccine did not effectively reduce the number of PRRSV related crises in the vaccinated farms.
Dynamics of influenza transmission in vaccinated and non-vaccinated pig populations
The objective of this study was to determine transmission parameters for an H1N1 influenza virus in vaccinated and non-vaccinated populations of pigs and assess the effect of vaccination on influenza transmission.
Estimation of time-dependent infectiousness of pigs infected by the PRRSV
The evolution of infectiousness was mainly correlated with the course of viral genome load in blood.
