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

Influence of pig gut microbiota on Mycoplasma hyopneumoniae susceptibility

In this open-access article from the MycoLab, Dr. Maria Pieters’ team explores the influence of pigs’ gut microbiome in modulating their susceptibility to Mycoplasma hyopneumoniae.

Piglet gut microbiota: a potential determinant for M. hyopneumoniae susceptibility

This week, we are sharing a report by the MycoLab regarding piglet microbiota and its potential influence of M.hyopneumoniae susceptibility.

Key points

  • Early life gut microbiota could be a potential determinant in modulating susceptibility to chronic respiratory diseases such as enzootic pneumonia in pigs.
  • Increased abundance of short‐chain fatty acid producing bacteria in piglet gut was associated with decreased M. hyopneumoniae respiratory lesions.  
  • Understanding the function and composition of a ‘healthy’ pig gut microbiota would aid to successfully implement novel disease control strategies.

Explore Lawsonia and the Swine Gut Microbiome: a podcast

In this episode of At the Meeting honoring Dr. Bob Morrison, the group discusses the swine gut microbiome and what is considered a good or bad microbiome.

Microbiome studies in swine systems: Challenges and opportunities(Part 2)

This week we are sharing part 2 of Dr. Gomez’s report on microbiome studies in swine. You may read part 1 over here if you missed last week.

Key points

  • Due to the nature of microbiome it cannot be studied separated from other relevant information and should be studied together with metabolomics, genomics, immunity and nutrition.
  • Development of models at different levels are needed to evaluate the effect on microbiome of different strategies and to evaluate the impact of microbiome changes on the pig gut health.
