Effect of Single Dose of Antimicrobial Administration at Birth on Fecal Microbiota Development and Prevalence of Antimicrobial Resistance Genes in Piglets

It is the end of the year and to celebrate, here is one of the favorite Science Pages of the year, from Dr. Lowe’s team at the University of Illinois.

Keypoints

  • Early life antimicrobial prophylaxis had no effect on individual weight gain, or mortality but it was associated with minor shifts in the composition of fecal microbiota and noticeable changes in the abundance of selected Antimicrobial Resistant Genes
  • The shifts in fecal microbiota structure caused by perinatal antimicrobial intervention are modest and limited to particular groups of microbial taxa
  • Early life PPG and TUL intervention could promote the selection of Anrimicrobial Resistant Genes in herds

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 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.

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

This is a favorite on the blog. Once a month, we are sharing with you a presentation given at the Allen D. Leman swine conference, on topics that the swine group found interesting, innovative or that lead to great discussions.

We can find all of the presentations selected from the previous years’ conferences on the blog here.

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.
