5.1% of 257 pig samples from Guangxi Province, China, tested positive for the novel porcine circovirus type 4 (PCV4) between 2015 and 2019. The study by researchers from Wenzhou University found 69.2% of PCV4-positive samples were coinfected with PCV2 or PCV3 and identified cross-protective immunogenicity potential between PCV2 and PCV4. This first seroprevalence and genetic investigation of PCV4 provides insights into the epidemiology and pathogenesis of this virus.
Use Cases
- Analyzing PCV4 prevalence and co-infection rates based on sample testing results.
- Studying genomic similarity and phylogenetic relationships based on nucleotide sequence alignments.
- Investigating cross-protective immunogenicity based on homologous antigen and receptor binding sites in Cap proteins.
Strengths
- Includes a specific sample size of 257 and a clear positive rate of 5.1%.
- Provides a defined temporal coverage from 2015 to 2019 and geographic focus on Guangxi Province, China.
- Contains detailed genetic analysis results, including nucleotide similarity percentages and homology findings.
Limitations
- Column-level documentation is absent; field semantics must be inferred after download.
- Row count is unknown, which may limit suitability assessment.
- Data may reflect geographic bias inherent to a single-province study.
