Construction Site Prep for new ADRDL begins!

Contractors provided the first tangible evidence of the new ADRDL construction project this past week, with site preparation and the removal of buildings to the north of the existing building.  The photo above shows site preparation (the old isolation building is to the left).   

Access to the east side of the ADRDL (receiving office and necropsy room unloading dock) remains intact, but the parking lot to the north and east of the ADRDL previously used by staff and faculty has been fenced off and permanently closed. 

In the weeks to come, contractors will work on relocating utilities utilized by the north outbuildings, continue structure removal, and perform selective site preparation work as weather permits. 

The photos below depict the view from the top of the existing ADRDL looking north, both before and after the removal of the old loafing shed.

Histology Lab at SDSU's ADRDL: Playing a Crucial Role in Animal Disease Diagnostics

It’s unlikely that most livestock producers or pet owners could easily define the term “histopathology.”  But the histopathology section within the South Dakota Animal Disease Research and Diagnostic Laboratory plays a key role in the diagnosis of animal diseases—not only in animals that have died (as a part of the necropsy), but in animals that are still alive as well (biopsy submissions).

This process begins with the submission of animal tissues, whether from a post-mortem examination in the field or a surgical biopsy from a live animal, in 10% neutral buffered... (Continue reading here)

Livestock Pathogens Surviving in Imported Feedstuffs: New Publication

Several SDSU ADRDL collaborators co-wrote a new publication describing research into the survival of important viral pathogens of livestock in animal feed ingredients imported daily into the United States. 

Drs. Fernando Bauermann, Jane Christopher-Hennings, Eric Nelson, and Diego Diel, along with SDSU scientists Aaron Singrey, Travis Clement, and Craig Long parcticipated in the work, led by Dr. Scott Dee, Pipestone Applied Research.  Collaborators from Kansas State University, Universidade Federal de Pelotas (Brazil), Lincoln Memorial University, and Iowa State University, also contributed. 

Eleven viruses of significance to global livestock production were examined, including Foot and Mouth Disease Virus (FMDV), Classical Swine Fever Virus (CSFV), African Swine Fever Virus (ASFV), and Porcine Reproductive and Respiratory Syndrome Virus (PRRSV). 

Virus survival in typical feed ingredients was evaluated using models that simulated the transport times and environmental conditions of Trans-Pacific or Trans-Atlantic shipments.  The researchers found that several important viral pathogens were able to maintain infectivity during transport, while others did not.  The research builds upon previous work that demonstrated the survivability of Porcine Epidemic Diarrhea Virus under similar conditions. 

The work provides further evidence of the risk of transport of livestock pathogens in feed, both domestically and globally.  See the full paper here for details on the specific viruses and feedstuffs evaluated.

Service, Therapy, and Assistance Animals Discussed at South Dakota One Health Seminar

More than 80 interested individuals attended the most recent "South Dakota One Health" seminar, held March 8 at the USD Health Science Center in Sioux Falls. Attendees heard speakers on six different topics ranging from the policies governing service, therapy, and assistance dogs to the benefits and risks of using animals for therapeutic purposes in healthcare settings such as hospitals, nursing homes, and assisted living centers. 

In addition to speakers, the meeting also featured several therapy and service dogs, in addition to Toby the therapy horse, pictured below with his handler, Shirlene Hvinden from New Ulm, MN. (Photo credit: Eric Dalseide, USD)

Presentations from the meeting will be available soon at

South Dakota One Health meetings are held twice yearly and represent a collaboration among SDSU Extension, USD Sanford Medical School, the South Dakota Department of Health, the South Dakota Animal Industry Board, and South Dakota Area Health Education Coalitions.
