Porcine Circovirus 2 Genotypes, Immunity and Vaccines: Multiple Genotypes but One Single Serotype
(MDPI, 2020-12-14)
Identified for the first time in the 1990s, Porcine circovirus 2 (PCV-2) should not be considered an emerging virus anymore. Nevertheless, many aspects of its biology and epidemiology are still ...
Revisiting the taxonomical classification of Porcine Circovirus type 2 (PCV2): still a real challenge
(BMC, 2015-08-28)
Background: PCV2 has emerged as one of the most devastating viral infections of swine farming, causing a relevant economic impact due to direct losses and control strategies expenses. Epidemiological ...
Comprehensive Analysis of Codon Usage Patterns in Chinese Porcine Circoviruses Based on Their Major Protein-Coding Sequences
(MDPI, 2022-01-03)
Porcine circoviruses (PCVs) are distributed in swine herds worldwide and represent a threat to the health of domestic pigs and the profits of the swine industry. Currently, four PCV species, including ...
Porcine circovirus 2 (PCV2) population study in experimentally infected pigs developing PCV2-systemic disease or a subclinical infection
(Nature Research, 2020-10-20)
Porcine circovirus 2 (PCV2) is a single stranded DNA virus with one of the highest mutation rates among DNA viruses. This ability allows it to generate a cloud of mutants constantly providing new ...
Porcine circovirus 2 (PCV-2) genotype update and proposal of a new genotyping methodology
(Public Library of Science, 2018-12-06)
Porcine circovirus 2 (PCV-2) is one of the most widespread viral infections of swine, causing a remarkable economic impact because of direct losses and indirect costs for its control. As other ssDNA ...
Porcine circovirus 3 (PCV-3) as a causal agent of disease in swine and a proposal of PCV-3 associated disease case definition
(Wiley, 2021-06-29)
Porcine circovirus 3 (PCV-3) was discovered in 2015 using next-generation sequencing (NGS) methods. Since then, the virus has been detected worldwide in pigs displaying several clinical-pathological ...
Genotyping of Porcine Circovirus 2 (PCV-2) in Vaccinated Pigs Suffering from PCV-2-Systemic Disease between 2009 and 2020 in Spain
(MDPI, 2021-08-12)
Vaccination against porcine circovirus 2 (PCV-2) is a common practice all over the world. Vaccines can prevent PCV-2-systemic disease (PCV-2-SD) outbreaks but not PCV-2 infection, which can be detectable ...
Porcine circovirus 3 (PCV-3) variability: Is it in the virus or in the classifcation criteria?
(BMC, 2023-02-09)
The continuous discovery of new viruses during the last decades has increased the need for new classification approaches and rules. Currently, the International Committee on Taxonomy of Viruses classifies ...
Current knowledge on Porcine circovirus 3 (PCV-3): A novel virus with a yet unknown impact on the swine industry
(Frontiers Media, 2018-12-12)
Porcine circovirus 3 (PCV-3) is a recently described virus belonging to the family Circoviridae. It represents the third member of genus Circovirus able to infect swine, together with PCV-1, considered ...
Lack of Porcine circovirus 4 Genome Detection in Pig Samples from Italy and Spain
(MDPI, 2020-05-31)
The genus Circovirus includes several species and mostly causes asymptomatic infections. Porcine circovirus 2 (PCV-2) and, with increasing evidence, Porcine circovirus 3 (PCV-3), have been associated ...
