Best of Leman 2021: Liz Wagstrom – Novel AMR patterns in Salmonella

This is our most popular series 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.

You can find all of the presentations selected from previous conferences on the blog here.

This month we learn about novel antimicrobial resistance patterns in Salmonella from Dr. Liz Wagstrom (National Pork Producers Council).

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

This week’s Science Page presents the results of a project done by Zeineldin et al. from Dr. Jim Lowe’s program 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
