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

Energy, amino acid, and phosphorus digestibility and energy prediction of thermally processed food waste sources for swine

This week, the swine nutrition team at the University of Minnesota is presenting their latest publication on food waste and its nutritional value.

Key Points

The digestibility of energy and nutrients of fish waste, supermarket waste, and vegetable waste was investigated.
Both fish and supermarket waste were excellent sources of digestible energy, metabolizable energy, and digestible amino acids
These food waste sources could be used to partially replace corn and soybean meal in swine diets to reduce environmental impact

Graduate student spotlight: Dr. Alyssa Betlach

Recently, Dr. Alyssa Betlach was featured as a Farm Journal’s PORK’s Up & Coming Leaders. Betlach is currently pursuing her PhD with Dr. Maria Pieters on Mycoplasma hyopneumoniae while working as an associate swine veterinarian with Swine Vet Center in St. Peter, MN.

Come see us in Atlanta at the 2020 AASV meeting!

This week-end is the 51st annual meeting of the American Association of Swine Veterinarians in Atlanta, GA. Numerous DVM students, graduate students, and faculty members from the University of Minnesota are presenting their latest research findings. Here is a summary table of presenters, topics, date and time. We are looking forward to seeing you there.

Senecavirus A continues to be present in the United States swine herd

This week, Dr. Guilherme Preis, graduate student at the University of Minnesota with Drs. Corzo and Vannucci is sharing an update on the prevalence of Senecavirus A in the United States.

Key Points

Senecavirus A continues to present in the US at low levels.
Sow herds are more likely to test positive than growing pig herds.
SVA positive herds tend to have a large number of positive samples.
