Dr. Matt Sturos, diagnostic pathologist at the University of Minnesota, Veterinary Diagnostic Laboratory will be presenting the latest information on Senecavirus A in swine, tomorrow at 4pm in a learning session organized by the Minnesota Veterinary Medical Association (MVMA). Participants can join in person at the MVMA conference room or online via WebEX.
The Allen D. Leman swine conference is only six months away! Our team is preparing an exciting conference program for you this year and we will update you regularly on the speakers and topics that will be covered during this great event bringing science-driven solutions to the complex challenges facing the swine industry. We already shared with you that the recipient of this year’s Science in Practice award is Dr. Bob Thompson.
We are glad to announce that our first key note speaker for the conference will be Gary Louis, Executive Vice President of Seaboard Foods LLC where he is in charge of the live operations. We are delighted that he has accepted our invitation to share his tremendous experience and his vision of the swine production.
More information about the Allen D. Leman swine conference can be found here.
The UMN CVM students did a fantastic job at the 2017 American Association of Swine Veterinarians (AASV) meeting this past weekend. Four students presented their projects as an oral presentation. Zhen Yang, Alyssa Anderson, Hunter Baldry and Chris Deegan were all recognized by a jury for their hard work and commitment to the swine industry.
Taylor Homann, Donna Drebes, and Kevin Gustafson all got the opportunity to present their work as poster presentations.
Lastly, two out of the three awards given by Boehringer Ingelheim to advance the research on swine respiratory pathogens were given to Dr. Marie Culhane and Dr. Carlos Vilalta for their project on swine influenza and Porcine Reproductive and Respiratory Syndrome virus (PRRSV) respectively.
The swine group was well represented at the 2017 MVMA meeting. Ms. Alyssa Anderson and Dr. Karine Ludwig Takeuti both gave a presentation on diagnostic tools to detect Mycoplasma hyopneumoniae infections. Drs. Jorge Garrido Mantilla and Fabian Chamba Pardo shared the latest update on swine influenza. Dr. Amy Kinsley explained how the structure of a swine farm can influence disease persistence. Dr. Talita Resende shared the advantages of a fairly recent diagnostic technique: in situ hybridization. Congratulations to Ms. Alyssa Anderson who also received a $5,000 Food Animal Scholarship from the MVM Foundation!
Next week-end will start the 48th American Association of Swine Veterinarians (AASV) meeting in Denver, CO. As usual, numerous UMN-CVM faculty and graduate students will be attending and presenting the results of their latest research. We hare looking forward to seeing you there!

Dr. Fernando Leite, a PhD student under the supervision of Dr. Richard Isaacson, won the Lynn Jones Memorial Award for the best oral presentation at the 97th Conference of Research Workers in Animal Diseases (CRWAD). His talk entitled “Lawsonia intracellularis vaccination decreases Salmonella enterica serovar Typhimurium shedding in co-infected pigs” presented the results of the work he did in collaboration with Drs. Gebhart, Singer, and Isaacson at the University of Minnesota.
Please join us in congratulating Fernando for his award!
Abstract: Salmonella enterica serovar Typhimurium and Lawsonia intracellularis are two of the most prevalent intestinal pathogens of swine. S. Typhimurium causes diarrhea but also results in subclinical persistent colonization of pigs and can lead to food borne illnesses. S. enterica is responsible for over 1 million cases of food borne illness per year in the United States. L. intracellularis infection has been found as a risk factor for increased S. Typhimurium shedding in swine. The objective of this study was to investigate if vaccination against L. intracellularis could lead to decreased S. Typhimurium shedding. To test this hypothesis, groups of nine pigs were either challenged with S. Typhimurium, S. Typhimurium and L. intracellularis, S. Typhimurium and vaccinated against L. intracellularis, or S. Typhimurium L. intracellularis and vaccinated against L. intracellularis. A non-infected control group served as a negative control. Fecal shedding of S. Typhimurium was monitored using an enrichment most probable number method two days after infection and weekly thereafter until animals reached the age of 14 weeks. The co-challenged vaccinated group had a tendency of shedding the least S. Typhimurium and at one-week post infection is when the greatest differences among groups was observed and the vaccinated co-challenged group shed significantly less Salmonella (p>0.05) than the group co-infected without vaccination and the group challenged with Salmonella alone. These differences were of 1.63 and 2.12 Log10 organisms per gram of feces, respectively. The instestinal microbiome of these animals is being investigated to understand how it may have impacted Salmonella shedding levels in the different treatments. These results indicate that vaccination against L. intracellularis may aid in the control of S. Typhimurium in herds co-infected with L. intracellularis.
Tuesday marked the end of the 2016 Allen D. Leman conference held in St. Paul, MN. The conference gathered more than 850 professionals and veterinarians from the swine industry for 4 days of conferences and exchanges on the latest science-driven solutions.
Among the highlights from this conference, we would like to congratulate Dr. Deb Murray from New Fashion Pork for receiving the Science in Practice Award. The Pijoan lecture was given by Dr. Peter Davies from the University of Minnesota whereas Dr. Paul Ruen from Fairmont Veterinary Clinic presented the Hanson lecture. Dr. Joe Connor was recognized as the Breakfast Conversation Honoree this year. Lastly, our Distinguished Lecturer, Dr. Alison Van Eenennaam challenged the audience on Genetically Modified Organisms (GMOs).
If you attended the conference, you may have received an email with a link to a survey. Please, consider taking a few minutes to answer it as we very much value your input and feedback.
Thank you and see you next year, September 16−19, for another amazing edition of the Allen D. Leman conference!
