Some breed-to-wean farms that have been vaccinated for porcine circovirus (PCV) have experienced breakdowns in their control of the virus. Clayton Johnson, DVM,...
DISCOVERIES, Issue 5: Fostera® Gold PCV MH, the inactivated vaccine from Zoetis developed to provide the broadest protection available against porcine circovirus type...
DISCOVERIES, Issue 21: A recent analysis of porcine circovirus type 2 (PCV2) genetic sequences shows that up to 25% of field strains are recombinants of diverse...
Effective PCV2 control relies on vaccination of healthy pigs before they become infected. This goal cannot be accomplished in unstable herds whose sows give birth to...
Porcine circovirus type 2 is the principal etiological agent of porcine circovirus associated disease (PCVAD), which can cost producers an estimated $3 to $4 per pig.
DISCOVERIES, Issue 6: When PCV2 first became a problem in US swine herds, scientists looked at taking the immunogenic capsid gene from PCV2 and cloning it into the...
PCV3 was first reported in 2016, but appears to have been present in swine populations decades prior to that time. PCV3 strains are similar to one another but are very...
A clinical outbreak of porcine circovirus type 2 (PCV2) occurred this past winter in otherwise healthy, well-vaccinated herds, Clayton Johnson, DVM, of Carthage...
Understanding the pathogen status of a sow herd helps determine the prevention, control and treatment options to protect piglets as they grow. For PCV2 there is no...
Clinical disease due to porcine circovirus type 2 (PCV2) has been dramatically reduced thanks to vaccination, but concern remains about the persistence of PCV2...
DISCOVERIES, Issue 16: Pigs in a study that received two doses of Fostera® Gold PCV MH, the new Zoetis vaccine for PCV2 and M. hyo, had numerically fewer reactions,...
DISCOVERIES, Issue 7: Compelling scientific evidence indicating the need for an updated porcine circovirus type 2 (PCV2) vaccine was the driving force behind the...
DISCOVERIES, Issue 8: Fostera® Gold PCV MH is the only USDA-licensed vaccine that protects pigs against porcine circovirus (PCV) type 2a, PCV2b and M. hyo for at least...
Genetic sequencing demonstrates that porcine circovirus type 3 (PCV3) is significantly different from PCV2, but otherwise little is known about the virus.
What is “cell-mediated immunity” and how does it affect vaccine performance? Are two PCV2 genotypes necessarily better than one? And what does a monster from Greek...
DISCOVERIES, Issue 4: Swine disease specialists speculated that a PCV2 vaccine containing two genotypes — PCV2a and PCV2b — would significantly improve the...
Anyone involved in raising pigs is aware of PCV2, but new on the scene is porcine circovirus type 3 (PCV3). Although the two viruses are both circular DNA viruses in...
DISCOVERIES, Issue 3: A large, commercial field trial conducted with Fostera® Gold PCV MH showed it was also effective against PCV2d, the most prevalent genotype of...
DISCOVERIES, Issue 1: Pigs vaccinated with Fostera® PCV MH were equally protected against porcine circovirus (PCV) type 2d as well as Mycoplasma hyopneumoniae (M. hyo)...
TOOLBOX, Issue 8: Rick Swalla, DVM, recently talked with editors of Pig Health Today about the pork industry’s first vaccine to include two genotypes of porcine...
The US pork industry’s first vaccine to include two genotypes of porcine circovirus type 2 (PCV2) — 2a and 2b — was announced on the first day of the American...
Three porcine circovirus (PCV) vaccines compared in a recent study equally protected pigs against PCV type 2d and Mycoplasma hyopneumoniae, but there were some...
Colostrum may be the best sample to test for determining whether porcine circovirus type 2 (PCV2) is present in sow herds, according to researchers at Iowa State...
The emergence of novel porcine circovirus-3 (PCV3) in US pig herds requires closer research into whether the disease is commonly circulating in the country’s hog...
