Head-to-head comparison of the level of protection and duration of immunity induced by different commercial and an autogenous PCV2 vaccine
January 30, 2009By Tanja Opriessnig
The study objectives were to compare the duration of immunity of commercially available, one and two dose, killed porcine circovirus type 2 (PCV2) vaccines. Sixty, 3.5-week-old pigs were randomly...

Determination of the amount of PCV2 needed for intrauterine transmission and assessment of effect of PCV2 exposure (natural and vaccine) prior to insemination
January 30, 2009By Tanja Opriessnig
Porcine circovirus type 2 (PCV2) is associated with reproductive failure in pregnant female pigs; however, the role of PCV2 in semen has not been elucidated. To determine the significance of semen in...
Swine Health - PRRS
Identification of protective epitopes toward developing a vaccine providing broad cross-protection against various PRRS viruses
December 15, 2008By Won-Il Kim
Enormous genetic and antigenic variation impedes effective control and prevention of PRRS. Since PRRS virus vaccination is shown to be effective only against homologous or closely related viruses,...

Inactivation of PRRSV using ultraviolet light
November 11, 2008By Jeffrey Zimmerman
The objective of this study was to calculate the inactivation of PRRSV by dose of UV254 in a “static” (i.e., virus-in-liquid solution) system. This study is the first step in...

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...

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...

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...
Pork Safety - Pre-Harvest
Identifying genes associated with Salmonella shedding to increase pork safety through improved genetic resistance
August 1, 2008By Christopher Tuggle
The long-term goals of this project are to use genomics tools to identify genetic variants associated with decreased Salmonella shedding on farms; and to use these variants to select for animals that...

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...

Genome sequencing of Haemophilus parasuis for improved swine health
July 8, 2008By Gregory Phillips
Although H. parasuis remains a concern to producers in the United States, it remains a challenging microorganism to study and thus control. For example, since H. parasuis is...
