This week, the MSHMP team assessed differences in ORF5 sequences compared to VR2332 based on the type of farm, the sequence was collected at.
Key points
- Breeding herd sequences differ 8%-16% while in other herd types they differ 1%-15% from VR2332 at the ORF5 level.
- The larger nucleotide identity (%) range compared to VR2332 in growing pigs suggests a higher viral diversity within this group.
