Importance of sequential order of coinfection by PRRSV and PCV2
This article proves that, at least "in vitro" order matters. In PRRSV/PCV2 mixed infections, the consequences are worse when PRRSV infection occurs before or concurrently to PCV2 infection, than when the sequence is reversed.
Seroprevalence of selected swine viral pathogens
The high seroprevalences found supports the feeling you get in the field that PCV2, PRRSV, and SIV are very widespread viruses in our farms.
The influence on performance in fattening pigs of L. intracellularis and PCV2 infections as measured in feces by Q-PCR
Vaccines and PCV2 evolution
Distinct PCV2 variants are circulating in commercial pig farms. How the vaccine induced immunity may affect PCV2 evolution?
PCV2 vaccination reduces antibiotic consumption in swine production
The benefit on antibiotic use is particularly clear when herds are multicontaminated by pathogenic virus and bacteria, allowing also to maintain animal welfare and operational productivity, but a good immunity against PCV2 is effective also in high health status herds.
The presence of six potentially pathogenic viruses in pigs suffering from post-weaning multisystemic wasting syndrome
DTH: A new option for checking the compliance of the vaccination against PCV2
It is a test that allows the verification of the carrying out and/or the quality of the vaccination in cases such as the entrance of piglets for their fattening.
Multiple routes of porcine circovirus type 2 transmission to piglets in the presence of maternal immunity
Effect of PCV2 vaccination on PCV2-viremic piglets after experimental PCV2 challenge
Vaccination failures in the control of PCV disease
The first cause of PCV vaccine failure is the purchase and use of generic vaccine of low quality and titre, but the exact cause of the failures can occur in various forms.
Influence of age on the effectiveness of PCV2 vaccination in piglets with high levels of maternally derived antibodies
Global gene expression profiling of myeloid immune cell subsets in response to in vitro challenge with PCV2b
Clinical case: Reproductive disorders in a newly established herd
The veterinarian is called from a new established herd in Brittany because some clinical signs appear on gilts from the two first deliveries introduced in the farm.
Novel PCV2 variants also known as mutant PCV2: Are current vaccines protective?
During 2012 PCV2 variants or mutants (mPCV2) appeared in the USA and were frequently associated with PCV-associated diseases. The possibility of lack of cross-protection of commercial vaccines against mPCV2 is now of major concern.
