Effect of Killed PRRSV Vaccine on Gut Microbiota Diversity in Pigs

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.

Researchers Fangfeng Yuan, Jaishree Sharma, Som G. Nanjappa, Christopher A. Gaulke, and Ying Fang from the University of Illinois at Urbana Champaign present information on the impact of killed PRRSV vaccine on the gut microbiome in today’s Science Page.

Relationships among Microbial Communities in Pigs

Today, we are sharing a recent article published in the journal Microorganisms by Dr. Valeris-Chacin and the MycoLab. The publication, available in open access, focuses on the relationships among fecal, air, oral, and tracheal microbial communities in pigs.

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.
