Investigating the Genetic Evolution of PCV2 and PCV3 across Six Swine Herds in China from 2020 to 2021

Chenchen Cui et al.

Summary: This study investigated the prevalence, molecular evolution, and coinfection of PCV2 and PCV3 in China through sample collection from six large-scale swine herds. The dominant genotypes of PCV2 and PCV3 varied across different regions, with PCV2d being the predominant genotype. The prevalence of PCV3 in China showed wide variation, and no dominant genotype was identified. The findings of this study provide important insights for the diagnosis, prevention, and control of PCV2 and PCV3 in China.

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

Giovanni Franzo et al.

Summary: The continuous discovery of new viruses has led to the need for new classification approaches. Currently, viruses are classified up to the species level, but lower level categorization is often necessary for epidemiological investigations. However, there is a lack of consensus and reproducibility in the criteria proposed by different research groups.

Molecular characterization of porcine circovirus-2 and-3 in pigs in Tanzania

Jelly S. Chang'a et al.

Summary: This study screened samples from 124 pigs in Tanzania collected between 2018 and 2022 for the presence of PCV-2 and PCV-3. Two genotypes of PCV-2 (a and d) were identified, while limited genetic heterogeneity was observed among PCV-3. This research provides important data on pathogens in Tanzanian pigs and is useful for veterinary authorities involved in porcine disease management.

Novel constructs and 1-step chromatography protocols for the production of Porcine Circovirus 2d (PCV2d) and Circovirus 3 (PCV3) subunit vaccine candidates

Amber R. Peswani et al.

Summary: This study presents a new production workflow for an updated and cost-effective PCV2d vaccine candidate, showing high yields of purified PCV2d-based antigen from E. coli fermentation systems and a chimeric PCV2d-PCV3 capsid construct. The recombinant protein effectively induced capsid-specific and PCV2d-neutralizing antibodies in immunized animals, suggesting significant potential as a new vaccine candidate that can be easily manufactured at commercial scale.

Identification of porcine circovirus-3 in Mozambique

Iolanda Vieira Anahory et al.

Summary: The study identified PCV-3 for the first time in Mozambique and Africa, and also revealed the first evidence of co-infection of PCV-3 and ASF virus. This finding should serve as a starting point for further investigations into the presence and impact of PCV-3 in Africa.

Current Understanding of the Pathogenesis of Porcine Circovirus 3

Chaitawat Sirisereewan et al.

Summary: Circoviruses are circular, single-stranded DNA viruses that belong to the family Circoviridae and genus Circovirus. Among them, porcine circoviruses (PCVs) are associated with various clinical symptoms and have limited understanding of their pathogenesis. Recent experimental infection studies provide valuable insights into PCV3 and its pathogenesis, addressing conflicting results and filling knowledge gaps.

Summary: As pig production increases in Africa, it is crucial to identify the pathogens circulating in the swine population to evaluate pig welfare and implement targeted control measures. A study in Nigeria found that 45% of pigs tested positive for two or more pathogens.

Porcine circovirus genotypes and their copathogens in pigs with respiratory disease in southern provinces of Vietnam

Phat Xuan Dinh et al.

Summary: This study investigated the genetic diversity of porcine circovirus type 2 (PCV2) and its coinfecting pathogens in pigs with respiratory disease in Vietnam. The predominant genotype of PCV2 was identified to be PCV2d in southern provinces of Vietnam. The study also provided a comprehensive overview of the coinfecting pathogens associated with PCV2 in young pigs with respiratory disease.

Pathogenicity and immune response against porcine circovirus type 3 infection in caesarean- derived, colostrum- deprived pigs

Gun Temeeyasen et al.

Summary: This study investigated the immunopathogenesis of PCV3 in CD/CD pigs and found that PCV3 can induce a prolonged viremia and mild multisystemic inflammatory response in infected pigs, with sustained viremia detectable for 42 days, induction of IgG humoral response, and viral shedding in nasal secretions. Further research is needed to understand the potential co-factors necessary for the manifestation and severity of clinical disease.

Porcine Circovirus 3 Detection in Aborted Fetuses and Stillborn Piglets from Swine Reproductive Failure Cases

Viviane Saporiti et al.

Summary: PCV-3 was detected in 33.9% of reproductive failure cases, with 16 cases where it was the sole pathogen found. It was found in mild histopathologic lesions in multiple tissues, emphasizing its potential role as a causative agent in swine reproductive failure.

Identification and whole-genome characterization of a novel Porcine Circovirus 3 subtype b strain from swine populations in Vietnam

Ngoc Hai Nguyen et al.

Summary: Porcine circovirus 3 (PCV3) is a novel circovirus identified in pigs suffering from various syndromes in Vietnam. A strain of PCV3 from southern Vietnam was found to have unique mutated sites and high sequence identity with other reference sequences. The public release of sequence data from this study will aid in further understanding the molecular characteristics and genetic diversity of PCV3.

Genetic Diversity of Porcine Circovirus Subtypes from Aborted Sow Fetuses in Vietnam

Ngoc Hai Nguyen et al.

Summary: PCV3 from aborted fetuses in Vietnam showed high sequence identity with reference PCV3 sequences, but with distinct mutations in Rep and Cap proteins. These strains were classified into two subtypes based on genetic variations. This study enhances the understanding of molecular characteristics and genetic diversity of PCV3 in Vietnam.

Viviane Saporiti et al.

Summary: PCV-3 was discovered in 2015 and has been detected worldwide in pigs with various outcomes. While many studies suggest PCV-3 as a potential pathogen, strong evidence of its causality is still lacking, requiring further research to establish clear connections.

PCV3 in Thailand: Molecular epidemiology and relationship with PCV2

Wansika Visuthsak et al.

Summary: The study found that there was no direct relationship between PCV3 and PCVAD-related clinical signs in Thai pigs, indicating that both viruses may originate from the same reservoir and have been circulating in Thailand for many years. Additionally, the viral load of PCV2 was found to be influenced by clinical signs.

Summary: PCV3 is a newly discovered virus detected in swine populations worldwide, with uncertain pathogenicity. There are at least six different lineages of PCV3 circulating in North and South American countries. Further studies are needed to determine the role of PCV3 in different clinical syndromes and its epidemiology in swine herds in the Americas.
