Veterinary students: Are you shadowing a swine practitioner this summer or have you been involved in an interesting clinical case investigation? Did you work on your veterinary skills by designing a differential diagnosis list or working on a treatment plan? Did you investigate a problem by analyzing production records? Share your work at the Allen D. Leman Swine Conference to win the Morrison Swine Innovator Prize!
The Allen D. Leman Swine Conference is organizing a session for veterinary students to demonstrate their problem-solving skills through the presentation of a case or experience where students challenged their clinical training and problem-solving capabilities necessary for day-to-day practice. Creativity and originality in the support and delivery are encouraged. The session will take place on Sunday at the Allen D. Leman Swine Conference and will include presentations from pre-selected veterinary students. Invited students will also be part of a dedicated workshop to enhance their leadership and communication skills, networking opportunities, and will receive a $1,000 stipend, free admission to the Leman Swine Conference, a copy of the Diseases of Swine book (10th edition), and of course the winner of the Morrison Swine Innovator Prize will receive a substantial monetary prize.
Attending the Leman Conference is a great opportunity for veterinary students who want to network with industry leaders. Submissions to enter in the selection to present at the DVM student session at the Leman Conference should be uploaded at z.umn.edu/MSIP by August 15th at the end of the day.
If you have any questions, please contact Dr. Perle Boyer at firstname.lastname@example.org. For more information about the Morrison Swine Innovator Prize visit z.umn.edu/MSIP.
Help us bring the IPVS back to the United States by supporting “Minneapolis 2022.” The last time the IPVS was held in the US was 2002, and before that, 1976. It’s time to bring it back!
We are thrilled to present the “Minneapolis 2022” bid at IPVS in China in June and working together with producers, veterinarians, academia and allied industry to make “Minneapolis 2022” the best IPVS ever! If you are attending IPVS China, please spread the word, join us at the booth and, of course, vote for “Minneapolis 2022” at the general meeting.
This week marks the first anniversary of the loss of Dr. Bob Morrison. Dr. Morrison was killed in a tragic car accident in the Czech Republic in May 2, 2017.
In that same accident, we also lost Pam Wetzell and Deb Spronk, spouses of our dear friends Dr. Gordon Spronk and Dr. Tom Wetzell. We remember them in many ways especially for their kindness and love of life.
Bob was a mentor, teacher, colleague, friend and inspirational leader to many of us.
We remember Bob for his kindness, integrity, fertile mind, dedication to his students, peers and the swine industry, and for his passion to instill in others to do work that matters.
Bob is dearly missed and continues to be an inspiration to many of us.
The UMN CVM students did a fantastic job at the 2018 American Association of Swine Veterinarians (AASV) meeting last week. Zhen Yang presented an update on his research regarding PCV3 and got the second place in the student oral competition.
Taylor Homann received a prize for her poster presentation. Marjorie Schleper was awarded one of the 10 student scholarships given by Merck Animal Health. Hunter Baldry was recognized for the most downloaded podcast: her interview of Dr. Clayton Johnson.
Lastly, Dr. Juan Sanhueza received one award given by Boehringer Ingelheim to advance the research on swine respiratory pathogens for his project: “Evaluation of parity as a delaying factor to reach PRRSv stability in sow farms”. Dr. Perle Boyer received a research grant from the AASV Foundation to develop Day 1 competencies for swine veterinary graduates.
In this study conducted by Dr. Sun during her PhD under the direction of Dr. Peter Davies, 66 swine veterinarians were sampled via nasal swabs every month for 18 months. Swabs were first cultured to detect Staphylococcus aureus and to determine the strains susceptibility (or resistance) to methicillin, and then were characterized by spa typing and MultiLocus Sequence typing (MLST).

S. aureus monthly prevalence ranged from 58% to 82% and MRSA ranged between 6% and 15%. Those results were higher than the ones for the US population. 52% of the swine veterinarians were classified as persistent carriers, meaning that their samples came back positive for S.aureus at least 80% of the time, 47% were intermittent carriers. 21% of the veterinarians were true persistent carriers meaning that the same spa type of S.aureus was recovered each time the sample was positive.
Whole genome sequencing showed that strains isolated at the beginning and at the end of the study were similar genetically. Comparing spa types, 83% of all isolates belonged to a type also present in swine.
People working with pigs are at elevated risk of harboring methicillin resistant S. aureus (MRSA) in their nose, which is attributable to occupational exposure to animals harboring livestock adapted S. aureus. To obtain insight into the biological nature of occupationally related nasal culture positivity, we conducted a longitudinal study of 66 swine veterinarians in the USA.
The study cohort resided in 15 US states and worked predominantly with swine. Monthly for 18 months, participants self-collected nasal swabs and completed a survey to report recent exposure to pigs and other animals; the occurrence of work related injuries; and any relevant health events such as skin and soft tissue infections or confirmed staphylococcal infections. Nasal swabs were cultured using selective methods to determine the presence of MRSA and methicillin susceptible S. aureus (MSSA), and isolates were characterized by spa typing and MLST.
Prevalences of S. aureus (64%, monthly range from 58 to 82%) and MRSA (9.5%; monthly range from 6 to15%) were higher than reported for the US population (30% and 1.5% respectively). Predominant spa types were t034 (ST398, 37%), t002 (ST5, 17%) and t337 (ST9/ST398 13%), a distribution similar to that found in a concurrent study in pigs in the USA. Veterinarians were classified into three groups: Persistent carriers (PC, 52%), Intermittent carriers (IC, 47%) and Non-carriers (NC, 1%). Persistent carriage of a single spa type was observed in 14 (21%) of participants, and paired (first and last) isolates from PC subjects had minor genetic differences. Swabs from PC veterinarians carried higher numbers of S. aureus. Among IC veterinarians, culture positivity was significantly associated with recent contact with pigs.
Exposure to pigs did not lead to prolonged colonization in most subjects, and the higher numbers of S. aureus in PC subjects suggests that unknown host factors may determine the likelihood of prolonged colonization by S. aureus of livestock origin. Exposure to S. aureus and persistent colonization of swine veterinarians was common but rarely associated with S. aureus disease.
We are trying to give you a daily update on the situation regarding the auto accident that happened in Prague on Tuesday and lead to Dr. Morrison’s passing.
As of today, Jeanie Morrison, Dr. Morrison’s wife, is no longer in a life-threatening condition said the doctors in charge of her recovery. We do not have any further information but the Morrison family is in the process of creating a online information page to provide updates on Jeanie’s situation. We will add the link here when it is available.
