Porcine circovirus 3 (PCV-3) variability: Is it in the virus or in the classification criteria? [PDF]

Virol J, 2023
AbstractThe 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 viruses up to the species level.

A case report of porcine circovirus 3 (PCV3) reproductive disease in Iberian semi-outdoor reared sows. [PDF]

Porcine Health Manag
Background Porcine circovirus 3 (PCV3) is a recently discovered swine pathogen associated with reproductive disease. To date, clinical problems linked to PCV3 have been described in intensive rearing pig farms.

Detection of Porcine Circovirus 3 in Wildlife Species in Spain. [PDF]

Pathogens, 2020
Porcine circovirus 3 (PCV-3) is the third member of the family Circoviridae, genus Circovirus, able to infect swine. A high prevalence of viral DNA has been recorded in wild boars. Recently, PCV-3 DNA was identified in Italian wild ruminants. Based on these previous results, this study assessed the frequency of PCV-3 DNA detection in free-ranging ...

Host immune response to infection with porcine circoviruses

Animal Diseases, 2021
Porcine circovirus type 2 (PCV2), which serves as a major causative agent of PCV2-associated diseases and causes severe loss to the pig industry worldwide, can dysregulate the immune response and induce immunosuppression in PCV2-infected pigs. Similar to

Evolution and Genetic Diversity of Porcine Circovirus 3 in China. [PDF]

Viruses, 2019
The identification of a new circovirus (Porcine Circovirus 3, PCV3) has raised concern because its impact on swine health is not fully known. In Fujian Province in eastern China, even its circulating status and genetic characteristics are unclear. Here, we tested 127 tissue samples from swine from Fujian Province that presented respiratory symptoms ...

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 ...

The Prevalence and Genetic Diversity of Porcine Circoviruses (PCVs) during 2017–2023 in Guangdong Province, China

Animals, 2023
Porcine circovirus disease poses a significant threat to the pig farming industry. Globally, four genotypes of porcine circovirus are circulating, with porcine circovirus type 2 and 3 (PCV2 and PCV3) being most strongly associated with clinical ...

Novel Circovirus in Blood from Intravenous Drug Users, Yunnan, China

Emerging Infectious Diseases, 2023
We identified a novel circovirus (human-associated circovirus 2 [HuCV2]) from the blood of 2 intravenous drug users in China who were infected with HIV-1, hepatitis C virus, or both. HuCV2 is most closely related to porcine circovirus 3.
