Article Synopsis
- Porcine circovirus 3 (PCV3) is a newly identified pathogen linked to reproductive issues in pigs, notably in intensive farming setups.
- A case study from a semi-outdoor Iberian sow farm highlighted significant reproductive disease symptoms, including a rise in mummified fetuses and stillborn piglets primarily among gilts, while multiparous sows remained unaffected.
- Investigations confirmed the presence of PCV3 through tissue analysis, displaying specific lesions such as lymphohistiocytic myocarditis, marking the first documented incidence of PCV3 reproductive disease in this farming system.
Article Synopsis
- - Porcine dermatitis and nephropathy syndrome (PDNS) is a serious condition affecting pigs, mainly linked to porcine circovirus 2 (PCV-2) and potentially associated with other strains (PCV-3 and PCV-4).
- - A study analyzed 102 PDNS cases through various methods like PCR and immunohistochemistry to investigate the presence of different porcine circoviruses.
- - Results showed that all PDNS cases tested positive for PCV-2, with a subset also showing PCV-3, while no link was found between PDNS and PCV-1 or PCV-4, reinforcing the idea that PCV-2 is likely the primary cause of PDNS
Article Synopsis
- * Key issues include difficulties in collecting and accessing reliable data, as well as the need for standardized information to enhance decision-making effectiveness.
- * A user-friendly and adaptable data tool is seen as essential for veterinarians, particularly independent practitioners, to monitor health conditions, visualize disease prevalence, and receive timely alerts for better disease management.
Porcine circovirus 3 (PCV-3) has emerged as a significant pathogen affecting global swine populations, yet its epidemiology and clinical implications remain incompletely understood. This retrospective study aimed to investigate the prevalence and histopathological features of PCV-3 infection in pigs from Switzerland, focusing on archival cases of suckling and weaner piglets presenting with suggestive lesions. An in-house qPCR assay was developed for detecting PCV-3 in frozen and formalin-fixed paraffin-embedded tissues, enhancing the national diagnostic capabilities.

The potential occurrence of PCV-3 in abortions from Swiss pig herds has not been investigated so far. Thus, we conducted a retrospective study on pig aborted cases submitted to our laboratory in the University of Bern during the last 10 years with the main aim of investigating the possible presence of PCV-3 in foetal and/or placental tissue.
