Effects of Porcine Circovirus Type 2 (PCV2) Maternal Antibodies on Experimental Infection of Piglets with PCV2 [PDF]

Clinical and Vaccine Immunology, 2005
ABSTRACTTo determine the effects of porcine circovirus type 2 (PCV2) maternal antibodies on and response to experimental PCV2 infection, 24 piglets were divided into four groups on the basis of the enzyme-linked immunosorbent assay titers of PCV2 maternal antibodies: group A (n= 6; sample/positive [S/P] ratio, <0.2), group B (n= 5;S/Pratio, >0.2 ...

Genetic characterization and phylogenetic analysis of porcine circovirus type 2 (PCV2) in Serbia

Archives of Virology, 2011
Porcine circovirus type 2 (PCV2) is the main causative agent of postweaning multisystemic wasting syndrome (PMWS). To characterize and determine the genetic diversity of PCV2 in the porcine population of Serbia, nucleotide and deduced amino acid sequences of the open reading frame 2 (ORF2) of PCV2 collected from the tissues of pigs that either had died

Porcine Lawsonia intracellularis Ileitis in Italy and Its Association with Porcine Circovirus Type 2 (PCV2) Infection. [PDF]

Animals (Basel), 2023
The objective of this study was to employ a diagnostic algorithm, which involves detecting positive farms by stool PCR followed by PCR and histology/immunohistochemistry on ileum samples, for diagnosing Lawsonia intracellularis proliferative enteritis in Northern Italy.

The Evaluation of a Porcine Circovirus Type 2 (PCV2) Intradermal Vaccine Against a PCV2 Field Strain. [PDF]

Vaccines (Basel)
Background/Objectives: Porcine circovirus type 2 (PCV2) has a major impact on swine productivity. Vaccines are used to aid in control and mitigate production losses. We investigated the protection provided by an intradermal PCV2 vaccine against a field strain in Taiwan. Methods: We conducted a safety and efficacy study.

Porcine circovirus type 2 (PCV2) genotyping in Austrian pigs in the years 2002 to 2017. [PDF]

BMC Vet Res, 2020
Abstract Background Eight different PCV2 genotypes with varying prevalence and clinical impact have been described so far. PCV2 infection is still widespread among the vaccinated population and several experimental studies have clearly demonstrated that there is no induction of a 100% cross-protective immunity between ...

Genetic analysis of porcine circovirus type 2 (PCV2) in Queensland, Australia [PDF]

Australian Veterinary Journal, 2020
ObjectiveTo determine the current porcine circovirus type 2 (PCV2) genotypes circulating in pigs in Queensland (QLD).MethodsThe PCV2 infection status of pigs was determined by real‐time PCR testing of 210 lymph nodes and 30 serum samples derived from 45 QLD farms.

Sensitive detection systems for infectious agents in xenotransplantation*

Xenotransplantation, EarlyView., 2020
Abstract Xenotransplantation of pig cells, tissues, or organs may be associated with transmission of porcine microorganisms, first of all of viruses, to the transplant recipient, potentially inducing a disease (zoonosis). I would like to define detection systems as the complex of sample generation, sample preparation, sample origin, time of sampling ...

Comparative Safety and Efficacy of Commercial Porcine Vaccines Against <i>Mycoplasma hyopneumoniae</i> and Porcine Circovirus Type 2 (PCV2). [PDF]

Animals (Basel)
Mycoplasma hyopneumoniae (Mhyo) and porcine circovirus type 2 (PCV2) infections cause enormous economic losses in the swine production sector. Vaccination remains the most effective strategy against the complex clinical entities caused by these pathogens.
