Antimicrobial resistance is an expression that everyone in swine production has heard at least once but what does it really mean? How are you as a producer or veterinarian affected?
In this column for the National Hog Farmer, Dr. Carles Vilalta explains that beyond the definition of a bacterium that is not affected by an antimicrobial, there are two different approaches to think about resistance:
One is determined by the Minimal Inhibitory Concentration or MIC, which records the minimum medicine concentration required to stop the growth of the bacteria.
The other focuses on the presence of genes enabling the bacterium to counteract the effect of the antimicrobial.
These genes are usually present in a sub-population of bacteria called mutants. The video below created by Harvard Medical School shows how these mutants can develop, adapt, and survive the highest antimicrobial concentrations. (video length < 2min)
This week, the Science Page honors Dr. Robert Morrison, the founder and leader of the Swine Health Monitoring Project.
Bob’s unique talent for creating relationships that advanced the swine industry culminated in the creation of the Swine Health Monitoring Project (SHMP), one of the initiatives that Bob carried with pride. […] As it evolved, the SHMP changed names several times but many in the industry simply refer to it as “Bob’s project”. For that reason, and to give the just recognition he deserves, we have decided to renam the project to “Dr. Bob Morrison’s SHMP” (MSHMP).
A lot of you are asking for news and updates of the situation in Prague, or how you can help. Everything is now centralized in a Caring Bridge web page for Jeanie. We are keeping the Morrison, Spronk, and Wetzell families in our thoughts and wish Jeanie a full and quick recovery.
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.
The University of Minnesota College of Veterinary Medicine is mourning the death of Dr. Robert Morrison, a faculty member in its Department of Veterinary Population Medicine. Dr. Morrison, his wife and several companions were involved in an auto accident north of Prague in the Czech Republic. They were traveling prior to attending a swine health management conference in Prague. “Dr. Morrison was an international leader in the swine industry,” says Dr. Trevor Ames, dean of the college. “This is a tragic loss for the strong team of students and faculty that Bob helped us build. Our thoughts and prayers are with the Morrison family.”
Dr. Morrison was hired by the University of Minnesota in 1986 and recently launched the Swine Health Monitoring Project, which provides weekly reports on the health status of over 50% of the U.S. sow herds. Dr. Morrison also coordinated two internationally-respected swine health management conferences: the St. Paul, MN-based Allen D. Leman Swine Conference and the Leman China Conference in Nanjing, China. The conferences are named for UM professor Dr. Al Leman, who served as Dr. Morrison’s graduate advisor.
