Porcine Circovirus Type 2 (PCV2): Pathogenesis and Interaction with the Immune System

Annual Review of Animal Biosciences, 2013
Porcine circovirus type 2 (PCV2) is the primary causative agent of porcine circovirus–associated disease (PCVAD). The virus preferentially targets the lymphoid tissues, which leads to lymphoid depletion and immunosuppression in pigs. The disease is exacerbated by immunostimulation or concurrent infections with other pathogens.

Differential Effects of Porcine Circovirus Type 2 (PCV2) Vaccination on PCV2 Genotypes at Japanese Pig Farms

Journal of Veterinary Medical Science, 2010
Infection of pigs with porcine circovirus type 2 (PCV2) causes a variety of disorders collectively referred to as porcine circovirus associated diseases (PCVADs). PCV2 isolates can be classified into two major types: PCV2a and PCV2b. In the present study, effects of vaccination on antibody titers in sera, PCV2 viremia, and shedding of PCV2 in feces ...

Porcine circovirus type 2 (PCV2) infections: Clinical signs, pathology and laboratory diagnosis

Virus Research, 2012
Clinical signs and pathological features are still the corner-stones to suspect and diagnose overt disease associated with PCV2 infection. The clinico-pathological scope of this viral infection has been expanded over time. From the initial description of postweaning multisystemic wasting syndrome, some enteric, respiratory and reproductive disorders ...

Detection of porcine Circovirus type 2 (PCV2) variants PCV2-1 and PCV2-2 in Brazilian pig population

Research in Veterinary Science, 2009
In the present study whole genome of six Brazilian isolates of PCV2 were sequenced, analyzed and compared with 35 other sequences (24 from other countries and 17 from Brazil). The phylogenetic analysis showed that mostly Brazilian variants of PCV2 were grouped as PCV2-1.

Origin of porcine circovirus type 2 (PCV2) from swine affected by PCV2‐associated diseases in Croatia

Veterinary Record, 2014
Porcine circovirus type 2 (PCV2) causes some of the most significant economic losses in pig production. Several multisystemic syndromes have been attributed to PCV2 infection, which are known as PCV2‐associated diseases (PCVDs). This study investigated the origin and evolution of PCV2 sequences in domestic pigs and wild boars affected by PCVDs in ...

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 ...

Effect of porcine circovirus type 2 (PCV2) vaccination on porcine reproductive and respiratory syndrome virus (PRRSV) and PCV2 coinfection

Veterinary Microbiology, 2008
The objectives were to determine if PCV2 vaccination is effective in reducing disease and lesions associated with PRRSV and PCV2 coinfection and if there is a difference between intradermal (ID) and intramuscular (IM) route of PCV2 vaccination. Seventy-four, 21-day-old pigs were randomly allocated into one of six groups.

Porcine circovirus type 2 (PCV2) vaccination reduces PCV2 in a PCV2 and Salmonella enterica serovar Choleraesuis coinfection model

Veterinary Microbiology, 2013
We previously reported that prior porcine circovirus type 2 (PCV2) infection potentiates the severity of clinical signs, lung lesions, and fecal shedding and tissue dissemination of Salmonella enterica serovar Choleraesuis in infected pigs. Here, we evaluated whether PCV2 vaccination is effective in reducing fecal shedding and tissue dissemination of S.

Shedding and infection dynamics of porcine circovirus type 2 (PCV2) after experimental infection

Veterinary Microbiology, 2011
The objective of this study was to determine the amount and infectivity of porcine circovirus type 2 (PCV2) shed in nasal, oral and fecal secretions following experimental infection. Fecal, oral and nasal swabs and blood were collected at regular intervals until 69 days post-inoculation (DPI) from five PCV2-experimentally inoculated pigs (Trial 1).

Shedding and infection dynamics of porcine circovirus type 2 (PCV2) after natural exposure

Veterinary Microbiology, 2011
The objective of this study was to determine the amount of porcine circovirus type 2 (PCV2) shed in nasal, oral and fecal secretions over time following natural PCV2 infection. Fecal, oral and nasal swabs and blood were collected at regular intervals starting at 28 days post-farrowing (DPF) until 209 DPF from four pigs naturally infected with PCV2 ...
