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.

- 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
M. hyopneumoniae causes one of the swine industry’s most devastating diseases—a chronic, infectious pneumonia that can cause respiratory distress and lung lesions in pigs. It can also severely slow pig growth. In order for producers and veterinarians to best measure the success of their disease control and elimination efforts, they need to be able to detect the pathogen in live pigs. However, many diagnostic tools can be unreliable. Dr. Maria Pieters’ lab at the University of Minnesota College of Veterinary Medicine recently led a study to decipher the reliability of two tools, laryngeal swabs and deep tracheal catheters, in detecting the pathogen.

This recent open-access publication in Frontiers expends beyond the realm of swine production and raises the question raising animals without using antibiotics. Dr. Singer from the University of Minnesota in collaboration with multiple other institutions surveyed US producers and veterinarians to gather their thoughts on the topic.

Aerosol transmission of Porcine Reproductive and Respiratory Syndrome virus is a major issue hog producers have had to deal with for several decades now. It encouraged the development of air filtration systems in farrow-to-wean farms as well as the isolation of high-value genetic lines in remote areas. This new publication, a collaboration between Dr. Arruda at the Ohio State University and Drs. Corzo and Torremorell from the University of Minnesota is a review of our knowledge of how PRRS is transmitted via aerosol.

In this new article published in the Preventative Veterinary Medicine journal, Dr. Paul Yeske from Swine Vet Center in collaboration with Dr. Maria Pieters from the University of Minnesota share a survival analysis of two different eradication methods for Mycoplasma hyopneumoniae in farrow-to-wean farms.
