Investigating the Presence and Genetic Variability of Porcine Circovirus Types 2 and 3 in Live Markets in Border Cities of Northeast China

Transboundary and Emerging Diseases, Volume 2025, Issue 1, 2025.
Bordering cities and farms serve as potential hotspots for the transboundary spread of animal infectious agents. This study aimed to investigate the presence and genetic variability of porcine circovirus types 2 (PCV2) and 3 (PCV3) in live markets across six border cities (Dandong, Ji’an, Hunchun, Mishan, Fuyuan, and Heihe) in northeast China.

Australian porcine circoviruses [PDF]

, 2006
Two types of porcine circovirus (PCV) exist, referred to as PCV1 and PCV2. PCV2 has been associated with disease syndromes in pigs, including that designated postweaning multisystemic wasting syndrome (PMWS), which has been identified in all regions of ...

Comparative Pathogenicity of PCV2, PCV3, and PCV4 in Piglets: Insights Into Clinical, Pathological, and Immunological Features

Transboundary and Emerging Diseases, Volume 2025, Issue 1, 2025.
Porcine circoviruses (PCVs) have been a significant concern in swine health, with PCV2 being a well‐established pathogen. However, the newly discovered PCV3 and PCV4 have emerged, and their impact on piglets remains less understood. Understanding their pathogenicity is crucial for effective porcine health management.

Retrospective Study Reveals Decades of PCV4 Circulation in Spain

Transboundary and Emerging Diseases, Volume 2025, Issue 1, 2025.
Porcine circovirus 4 (PCV4) was first identified in China in 2019 and retrospectively traced back to 2008. However, unlike other circoviruses, its distribution appeared to be largely confined to Asian countries until recent reports from Spain and the United States.

Abscessos dentários periapicais em leitões com síndrome multissistêmica do definhamento Dental periapical abscesses in piglets affected by postweaning multisystemic wasting syndrome PMWS

Pesquisa Veterinária Brasileira, 2008
Duzentos e oitenta leitões, entre 40 e 70 dias de idade, afetados pela sindrome multissistêmica do definhamento (SMD) foram examinados após eutanásia para pesquisa de lesões dentárias. Pelo menos um abscesso periapical foi observado em 58 leitões (20,7%),

Postweaning Multisystemic Wasting Syndrome (PMWS) Surveillance Study

, 2005
PMWS is characterized by a clinical history of wasting or poor performance in weaned pigs and by severe lymphoid depletion and histiocytic replacement of follicles in lymphoid tissues. The detection of porcine circovirus type 2 (PCV2) antigen or nucleic acids within characteristic microscopic lesions is required for the diagnosis of PMWS.

A panoramic view of the virosphere in three wastewater treatment plants by integrating viral‐like particle‐concentrated and traditional non‐concentrated metagenomic approaches

iMeta, Volume 3, Issue 3, June 2024.
Our comparative analysis unveiled the distinct advantages of two methods in capturing the complexity of viral communities and their functions in wastewater treatment plants. The non‐concentrated (NC) metagenomic approach identified a higher number of viral contigs, though it had a lower yield of high‐quality contigs.
