Improving Swine Health: Enhancing Humoral and Cell-Mediated Immunity Using Novel Polymer Adjuvants
November 2, 2008By Michael Wannameuhler
As commodity markets fluctuate and producer profit margins diminish, economic loss due to infectious disease become even more important to the survivability of operations. Vaccination continues to be...

The Comparative T-cell Repertoire Response in PRRSV, SIV and PCV2 Infected Piglets
October 13, 2008By John Butler
Viral infection exposes the host immune system to epitopes that are normally recognized by T cells and which leads to both cytotoxic responses against virus-infected cells and to B cells that make...

Development of a simple on-site diagnostic test to detect PRRSV acute infection in boar studs
October 8, 2008By Claudia Munoz-Zanai
Because PRRSV can be transmitted through artificial insemination with semen from infected animals, boar studs are constantly being monitored for the presence of PRRSV. Current monitoring protocols...

Enhanced virulence and treatment of multiple antibiotic resistant Salmonella choleraesuis in swine
October 3, 2008By Dr. Steve Carlson|Michael Kimber
Previous studies revealed that protozoa (amoebae) can augment the virulence (ability to cause disease) of certain Salmonella strains that are resistant to multiple antibiotics. This phenomenon has...

B Cell Repertoire Diversification and Class Switch in PRRS
September 26, 2008By John Butler
Successful PRRSV vaccines and vaccination strategies are best employed when the host’s immune response to the pathogen is understood. Since it was generally known that PRRSV caused non-virus...

Effects of high and low virulent PCV2 on activated PBMC populations
August 26, 2008By Dr. Eileen Thacker
Porcine circovirus type 2 (PCV2) associated diseases (PCVAD) have been an important cause of mortality and economic loss to the swine industry. The importance of virulence between different virus...

Development of a live attenuated vaccine against swine influenza by reverse genetics
July 17, 2008By Yan Zhou
Influenza A virus causes significant morbidity in swine, resulting in a substantial economic burden. Vaccination is the primary method for the prevention of influenza disease. Live virus vaccines...

Investigations on breed-dependent differences in susceptibility to PCV2
July 11, 2008By Tanja Opriessnig
Anecdotal information from producers and veterinarians in the field suggests that there are differences in susceptibility to porcine circovirus type 2 associated disease (PCVAD). Some producers have...

Identification of a putative viral co-factor different from PCV2, in animals with PMWS.
July 11, 2008By Israrul Ansari
During the last two years, the availability of effective vaccines against PCV2 and their extensive successful use under field conditions to control PMWS have allowed to convincingly demonstrate that...
