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.


  • 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
