Salmonella: How can we fight ‘smart’ bacteria?

Salmonella is an older pathogen, well-known in the swine industry. However, clinical signs of salmonellosis are still seen on the farm, sometimes despite the use of vaccines. Dr. Matheus Costa and graduate student Mariana Meneguzzi explain why this might be due to the great variety of Salmonella found in pigs in an article for the National Hog Farmer.

Frequency and destination of live exports of breeding-stock pigs from the United States

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.

This week, the MSHMP team in association with SHIC is a mirror of a previous report about the import of breeding stock and focuses on the export of these animals.

Monitoring and updating the value of productivity losses due to PRRSv

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.

This week, we are sharing a report from Drs. Holtkamp and Linhares in association with the MSHMP team, regarding the updated cost of PRRS for the US industry.

Keypoints

  • Productivity in breeding herds affected by PRRSV relative to unaffected herds has improved since 2010, suggesting producers and veterinarians have made progress in controlling PRRSV.
  • Combined effect of these changes resulted in a net reduction in the value of productivity losses due to PRRSV of $138 million, a 20.8% reduction compared to the $664 million per year estimated in 2010.

A roadmap to Food Animal Careers at the UMN CVM

Today we are sharing a publication in the Journal of Veterinary Medical Education from Dr. Perle Boyer (Zhitnitskiy) presenting a new online tool for students enrolled at the University of Minnesota, College of Veterinary Medicine to choose selective course tailored to their career path.

How does giving tulathromycin at birth impact the fecal microbiota?

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.

This week’s Science Page presents the second part of a project done by Zeineldin et al. from Dr. Jim Lowe’s program at the University of Illinois. The first part is available here.

Keypoints

  • Fluctuations in antimicrobial resistance genes (ARGs) associated with the developing gastrointestinal microbiota have not been elucidated
  • The swine fecal microbiota and their accompanying ARGs were diverse and established soon after birth
  • Results indicate that the perinatal TUL metaphylaxis has no measurable beneficial or detriment impacts on fecal microbiota structure and abundance of ARGs in pre-weaned piglets
