Podcast: Conversations around African Swine Fever

Happy holidays everyone! The swine group at the University of Minnesota wishes you the most wonderful time, surrounded by friends and family.

Podcasts are a perfect way to get caught up with new swine information! We are presenting you the latest episode from “At The Meeting… Honoring Dr. Bob Morrison” in collaboration with SwineCast.

The latest episode of At the meeting… sees our hosts and their invited speaker talk about African Swine Fever: what is the current situation?

Characterization of Broadly Neutralizing Antibodies to PRRSV

This week, Dr. Jordan Young from the late Dr. Murtaugh‘s lab shares his latest research project regarding the immune response against PRRS.

Key point

PRRSV antibodies were determined to be broadly binding, but only homologously neutralizing, suggesting a polyclonal response, involving multiple PRRSV specific antibodies might be necessary for PRRSV neutralization.
This means that vaccinations aiming to protect from infection likely need to involve exposure to multiple strains of PRRSV to induce a broad protective immunity, rather than relying on single-strain vaccines.

Best of Leman 2019 #2: J. Nerem and J. Schwartz – Investigating silent estrus in gilts

Our second selection from the past Leman conference is actually two presentations from practitioners regarding silent estrus in gilts. Dr. Joel Nerem works in Pipestone Veterinary Services and Dr. Jake Schwartz is with Swine Vet Center. Both share their experience dealing with this issue.

PRRSv ORF5 difference from VR2332 by herd type

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.

Survival analysis of two Mycoplasma hyopneumoniae eradication methods

In this new article published in the Preventative Veterinary Medicine journal, Dr. Paul Yeske from Swine Vet Center in collaboration with Dr. Maria Pieters from the University of Minnesota share a survival analysis of two different eradication methods for Mycoplasma hyopneumoniae in farrow-to-wean farms.
