Genetic analysis of porcine circovirus type 2 in China

Archives of Virology, 2017
Porcine circovirus type 2 (PCV2) is the cause of postweaning multisystemic wasting syndrome (PMWS), which encompasses several distinct symptoms in pigs. PCV2 infection and clinical incidence of PMWS have increased in recent years, possibly due to shifts in viral populations and mutations.

Replication and transmission of porcine circovirus type 2 in mice

Acta Veterinaria Hungarica, 2008
Little information is known about infection, replication and transmission of porcine circovirus type 2 (PCV2) in species other than swine. Two sets of animal experiments were carried out to investigate the susceptibility of mice to PCV2 and to study their possible role in maintaining and transmitting the virus.

Immunologic Features of Porcine Circovirus Type 2 Infection

Viral Immunology, 2002
Clinical expression of porcine circovirus 2 (PCV-2) infection in swine may result in two distinct high mortality disease syndromes. In North America, postweaning multisystemic wasting syndrome (PMWS), while still sporadic in incidence, predominates. In Europe and elsewhere, both PMWS and a second syndrome, porcine dermatitis and nephropathy syndrome ...

Recombination of two porcine circovirus type 2 strains

Archives of Virology, 2009
Pigs can be concurrently infected with different PCV2 strains. In this study, a cell-culture-adapted PCV2 strain, originating from a PMWS-affected pig, was purified by limiting dilution. Three different strains were obtained, and one of them was a perfect mosaic of the other two, with recombination breakpoints in ORF1 and ORF2.

Proteomic analysis of porcine alveolar macrophages infected with porcine circovirus type 2

Journal of Proteomics, 2012
Post-weaning multi-systemic wasting syndrome (PMWS), which is primarily caused by porcine circovirus type 2 (PCV2), is an emerging swine immunosuppressive disease. To characterize the interaction between target immune cells and PCV2, the differential proteomes of porcine alveolar macrophages, with and without PCV2 infection, were analyzed at different ...

Does porcine circovirus type 3 (PCV3) interfere with porcine circovirus type 2 (PCV2) vaccine efficacy?

Transboundary and Emerging Diseases, 2019
PCV2 is globally spread pathogen involved in a number of diseases (PCVD). Commonly used vaccines against PCV2 are proved to be highly efficacious. The role of recently discovered PCV3 for pig health and interference with PCV2 remains unknown. The study performed on serum samples from seven farms vaccinated against PCV2 and four non-vaccinated showed ...

Genetic characterization of porcine circovirus type 2 in Republic of Korea

Research in Veterinary Science, 2008
Porcine circovirus type 2 (PCV2) is a major causative agent of postweaning multisystemic wasting syndrome (PMWS). Sequence and phylogenetic analyses based on the ORF2 capsid protein gene fragment showed that field isolate in Republic of Korea (ROK), PCV2 YJK 0703, was closely related with the PCV2 Fh18 isolate.

T Lymphocyte Epitope Mapping of Porcine Circovirus Type 2

Viral Immunology, 2007
Immunoreactive T lymphocyte epitopes within the ORF1, ORF2, and ORF 3 products of porcine circovirus type 2 (PCV2) were mapped. For this, overlapping linear 20-mer peptides were synthesized and tested for their ability to induce T lymphocyte proliferation in porcine peripheral blood mononuclear cells (PBMCs) isolated from experimentally PCV2-infected ...

Development of haemagglutination assay for titration of porcine circovirus type 2

Analytical Biochemistry, 2020
Porcine circovirus type 2 (PCV2) was one of the most economically important viral pathogens in all the swine-producing countries and often resulted in tremendous economic losses for the swine industry. As PCV2 could not cause cytopathogenic effects while propagated in infected cells, many complicated experiments should be performed to titrate its virus

Susceptibility of pig embryos to porcine circovirus type 2 infection

Theriogenology, 2004
The aim of the present study was to determine if porcine circovirus type 2 (PCV2) is able to infect embryonic cells of in vivo produced porcine embryos with and without zona pellucida (ZP). ZP-intact and ZP-free morulae (6-day post-insemination) and early blastocysts (7-day post-insemination), and hatched blastocysts (8-day post-insemination) were ...
