Modification of PCV-2 virulence by substitution of the genogroup motif of the capsid protein [PDF]

Veterinary Research, 2011
Porcine circovirus type 2 (PCV-2) is the causal agent of the post-weaning multisystemic wasting syndrome (PMWS). PCV-2 are small single-stranded circular DNA viruses clustered into two main genogroups: PCV-2a and PCV-2b. Each genogroup present a specific

Detection and genotyping of Porcine circovirus 2 (PCV‐2) and detection of Porcine circovirus 3 (PCV‐3) in sera from fattening pigs of different European countries [PDF]

Transboundary and Emerging Diseases, 2020
PCV-2 is considered one of the most economically important viral agents in swine worldwide. Recently, PCV-3 has been found in pigs affected by different disorders and in healthy animals.

Porcine circovirus 2 (PCV-2) genetic variability under natural infection scenario reveals a complex network of viral quasispecies [PDF]

Scientific Reports, 2018
Porcine circovirus 2 (PCV-2) is a virus characterized by a high evolutionary rate, promoting the potential emergence of different genotypes and strains. Despite the likely relevance in the emergence of new PCV-2 variants, the subtle evolutionary patterns

A Methodology for Porcine Circovirus 2 (PCV-2) Quantification Based on Gold Nanoparticles. [PDF]

Materials (Basel), 2020
The aim of the current study is to introduce a methodology aimed at producing a biosensor that uses gold nanoparticles (AuNPs) to detect porcine circovirus 2 (PCV-2). This biosensor was based on AuNPs, which were modified with self-assembled monolayers (SAMs) and antibodies.

Frequency of PCV-2 viremia in nursery piglets from a Spanish swine integration system in 2020 and 2022 considering PRRSV infection status [PDF]

Porcine Health Management
Background Porcine circovirus 2 (PCV-2) poses a significant economic threat for the swine industry, causing a range of diseases collectively referred to as porcine circovirus diseases (PCVDs).

Assessment of sow herd frequency of PCV-2 using placental umbilical cord serum and serology in 18 breeding farms in Brazil [PDF]

Frontiers in Veterinary Science
Porcine circovirus type 2 (PCV-2) is the agent of one of the most important diseases in the swine industry. Although it has been controlled through vaccination, viremic piglets at birth may represent a risk by reducing vaccination efficacy.

Erste diagnostizierte PCV-2-bedingte „SMEDI-Fälle“ in der Schweiz [PDF]

Tierärztliche Praxis Ausgabe G: Großtiere / Nutztiere, 2011
Der Ausdruck SMEDI (Stillbirth, Mummification, Embryonic Death, Infertility) ist seit langem als Krankheitsbegriff für Fruchtbarkeitsstörungen beim Schwein auch im deutschen Sprachraum weit verbreitet. Als wesentliche Ursachen hierfür werden Virusinfektionen,insbesondere das porzine Parvovirus (PPV) und porzine Enteroviren (20) genannt.

Comparison of Three Enzyme-Linked Immunosorbent Assays to Detect Porcine Circovirus-2 (PCV-2)—Specific Antibodies after Vaccination or Inoculation of Pigs with Distinct PCV-1 or PCV-2 Isolates [PDF]

Journal of Veterinary Diagnostic Investigation, 2008
Porcine circovirus-2 (PCV-2) serology is frequently used to determine PCV-2 status and optimal timing of PCV-2 vaccination in the field. The objectives of the current study are to determine the diagnostic accuracy of 3 currently available commercial anti-immunoglobulin G (IgG) PCV-2 enzyme-linked immunosorbent assays (ELISAs) and to compare the ability

Descriptive analyses of maternally-derived antibody levels against porcine circovirus 2 (PCV-2) in 3- and 21-day-old piglets from farms of four European countries using different vaccination protocols in sows [PDF]

Porcine Health Management, 2022
Background Up to now, information on the levels of maternally-derived antibodies (MDA) against PCV-2 in suckling piglets born to sows vaccinated with different strategies is scarce in the literature. In the present observational study, the PCV-2-specific

A Shift in Porcine Circovirus 3 (PCV‐3) History Paradigm: Phylodynamic Analyses Reveal an Ancient Origin and Prolonged Undetected Circulation in the Worldwide Swine Population

Advanced Science, 2019
The identification of a new circovirus (Porcine circovirus 3, PCV‐3) has raised a remarkable concern because of some analogies with Porcine circovirus 2 (PCV‐2).
