Optimal routes of administration
How to administer drugs in order to optimize the speed of action, the efficiency and the financial cost.
Update on the importance of porcine circovirus type 2 (PCV2) subclinical infection
Might be there is a little doubt nowadays on the beneficial clinical and economic effects of PCV2 vaccination in subclinical infections in piglets, but… which is the role that sows play in the whole picture?
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.
Effect of influenza vaccination on influenza bioaerosol generation
In this study, influenza virus detection in pigs and air samples was reduced through vaccination.
Porcine circovirus type 2 (PCV2) infection decreases the efficacy of an attenuated classical swine fever virus (CSFV) vaccine
The aim of this study was to investigate whether PCV2 infection affects the efficacy of the LPC vaccine.
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.
Mycoplasma hyorhinis - not just a commensal
Although a commensal, M. hyorhinis may cause serious systemic disease through mechanisms that are not fully understood.
Vaccination of sows reduces the prevalence of PCV-2 viraemia in their piglets under field conditions
Under the study conditions, dam vaccination reduced PCV-2 viraemia in the offspring with colostrum access.
Novel cell line identifies all Foot-and-Mouth virus serotypes
The new cells detect the FMD virus in field samples that come directly from naturally infected animals faster than existing cell lines currently used for diagnostics.
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.
