National reduction in PCV2 prevalence following introduction of vaccination
Since the introduction of PCV2 vaccines in 2006, viral presence and viral loads have greatly decreased, and a genotypic shift dominated by PCV2b has occurred.
Comparative efficacy of concurrent administration of a PCV2 vaccine plus a PRRSV in pigs challenged with both viruses
Under the conditions of this study, it makes no difference to protection whether PCV2 and PRRSV vaccines are administered concurrently. Concurrent vaccination is efficacious for controlling co-infection with PCV2 and PRRSV.
Transdermal devices in PRRSV immunization (1/2)
NFID administered swine vaccines can use half to a tenth of the dose required for intramuscular vaccines because of the higher antigen dispersion and contact with the antigen presenting cells found in skin.
The challenge of Porcine Circovirus type 2 (PCV2) intra-specific taxonomic classification
All available vaccines in the European and North-American market are based on PCV2a genotype, while the most prevalent ones are PCV2b and PCV2d ones. Although significant level of cross-protection among these three genotypes has been demonstrated, it would be interesting to assess if vaccine efficiency would be equivalent in front of all these different genotypes.
Heterologous challenge in the presence of maternally-derived antibodies results in vaccine-associated enhanced respiratory disease in weaned piglets
Our data indicates that although high titers of vaccine-derived MDA reduced homologous virus infection, transmission, and disease, MDA alone was sufficient to induce vaccine associated enhanced respiratory disease upon heterologous infection.
How PCV2 vaccines work
Despite not having a consistent post-vaccination serological reaction, vaccinated animals behave differently from unvaccinated animals under field conditions.The article explains why vaccines offer protection.
Live attenuated African swine fever viruses as ideal tools to dissect the mechanisms involved in viral pathogenesis and immune protection
The findings will be of utility for a better understanding of ASFV pathogenesis and for the rational designing of safe and efficient vaccines against this virus.
Post-weaning E. coli immunity
In practice, and to have active-acquired antibodies ready at weaning, piglets should be immunised 10 days to 2 weeks before weaning.
Effect of vaccination against PRRSV on virus shedding
Effect of modified-live porcine reproductive and respiratory syndrome virus vaccine on the shedding of wild-type virus from an infected population of growing pigs.
European Union: Progress on two proposals considered as a package on "Animal medicines"
The Presidency reported to the Agriculture and Fisheries Council on the progress achieved during the second half of 2015 on two proposals considered as a package on 'Animal medicines'.
Use of a live attenuated Salmonella enterica serovar Typhimurium vaccine
These findings indicate that vaccination with an attenuated S. Typhimurium strain reduces S. enterica shedding, but the reduction is not consistent and the vaccine strain may persist in tissues.
Efficacy of a live attenuated vaccine in classical swine fever virus postnatally persistently infected pigs
To our knowledge, this is the first report demonstrating the absence of a response to vaccination in CSFV persistently infected pigs.
Stochastic model of PRRSV control strategies on a swine farm in the United States
After 24 years of experience we still don't have a control plan agreed upon and accepted by all our technical community. Why?
Oral vaccine platform based on the yeast Saccharomyces cerevisiae to combat PCV2
The results presented here demonstrate a possible use for recombinant S. cerevisiae expressing viral proteins as an oral vaccine against PCV2.
Efficacy of combined vaccination against Mycoplasma hyopneumoniae and porcine reproductive and respiratory syndrome virus in dually infected pigs
In conclusion, combined vaccination against both Mhp and PRRSV efficiently pooled the efficacy of each single PRRSV and Mhp vaccination and could be an interesting tool to control PRDC in European swine production.
