Dr. Ilya Slizovskiy receives new USDA-FSIS fellowship

Dr. Ilya Slizovskiy, PhD student in the Noyes lab, is the first recipient of a new fellowship created by the Food Safety Inspection Service, FSIS.  This competitive fellowship is committed to data-driven and science-based approaches applied to all aspects of FSIS public health mission. Slizovskiy’s project focuses on new techniques to detect antimicrobial resistances and foodborne pathogens.

Antimicrobial resistance in swine respiratory bacterial pathogens in the USA

On this Monday morning, we would like to share with you this article published in Research in Veterinary Science by PhD-candidate Shivdeep Hayer advised by Dr. Julio Alvarez. The peer-reviewed publication is a summary of antimicrobial resistances (AMR) in swine respiratory isolates between 2006 and 2016.

Highlights

  • AMR data for bacterial swine pathogens associated with Swine Respiratory Disease Complex are lacking
  • AMR data on swine bacterial pathogens collected over 11 years in the U.S.A was analyzed for changes in AMR prevalence
  • AMR in S. suis and P. multocida isolates mostly remained low
  • There were statistically significant changes in AMR in A. suis and H. parasuis
  • Use of surrogate breakpoints can lead to different AMR estimates for certain bacteria

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

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.

Best of Leman 2018 series #6: M. Costa – Guts and bugs: understanding colitis to fight AMR

Our sixth presentation is by Dr. Matheus Costa, our newest colleague in the swine group, about his work on colitis and antimicrobial resistance when he was working at the University of Saskatchewan.
