This is our Friday rubric: every week a new Science Page from the Bob Morrison’s Swine Health Monitoring Project. The previous editions of the science page are available on our website.
- Two novel HP-PRRSV variants (XJ17-5 and JSTZ1712-12) that have the new genetic feature of 150-amino-acid deletion in nsp2 were identified.
- Even though XJ17-5 and JSTZ1712-12 isolates share high genomic homology, they had distinct pathogenicity for piglets.
- Fragment comparisons identified 34 amino acid differences between the two isolates which might be related to distinct virulence.
