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...

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...

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...

The role of boar semen in porcine circovirus type 2 (PCV2) transmission: Validation of diagnostic tools and determination of infectivity of PCV2 positive semen samples
June 25, 2008By Patrick Halbur
Within the past 3 years, North American has seen a marked increase in porcine circovirus type 2 (PCV2) associated disease (PCVAD). The rapid spread of PCVAD has raised important questions about...

Understanding if porcine circovirus type 2 strain differences explain the recent Canadian outbreak
June 25, 2008By Patrick Halbur
In 2004, a marked increase in the incidence and severity of porcine circovirus associated disease (PCVAD) was observed in eastern Canada. The severe outbreaks of PCVAD in Canada, followed by similar...

Characterizing level of PCV type 2 virus in serum and expression of PMWS in different populations of pigs
May 19, 2008By Rodger Johnson
Selection for resistance to PCV2 virus is possible. It can be accomplished by serially scoring pigs for symptoms of PCVAD from 60 to 125 d of age, weighing pigs at these ages, and measuring serum...
