We are committed to provide continuous diagnostic services for our clients while providing safety for our staff and Faculty during the ever-changing COVID 19 issues. Currently, the laboratory is continuing to tests samples, but due to some split shifts and to help ensure the fastest turnaround times for molecular diagnostic testing, please drop off high priority samples prior to 9AM. If you have specific questions concerning molecular diagnostics testing, call Travis at 605/688-5645.
For any diagnostic sample drop offs, please use our drive up window on the west side of the building or the necropsy drive up bay. If you have any comments or questions, please contact the laboratory at 605/688-5171. Thank you for your consideration and patience.
Dr. Tamer Sharafeldin Joins ADRDL as New Pathologist; Brings Poultry Expertise
Dr. Tamer Sharafeldin is the ADRDL's new pathologist, beginning his work at SDSU on June 1. Dr. Sharafeldin received his professional pathology training and his PhD at the University of Minnesota. While his work will include all the routine casework coming through the diagnostic lab, Dr. Sharafeldin brings a particular expertise in poultry diseases to SDSU. He has wide experience with a variety of poultry production systems including turkey and layer production as well as game birds in Minnesota and Pennsylvania. He is one of the pioneers who studied the pathogenesis and the immune response of turkey arthritis/tenosynovitis reovirus. He has a nationally recognized turkey reovirus research program that received research grants to study and develop turkey reovirus vaccines.
Tamer is working with colleagues at SDSU to expand poultry diagnostics in support of turkey and layer production systems in the upper Midwest. "The ADRDL has an already-strong reputation for diagnostics development. By submitting poultry cases to SDSU you're not only benefiting from diagnostic service from an experienced avian pathologist, but you're also helping support the development of more diagnostics here at SDSU."
Contact Dr. Sharafeldin with questions at 605-688-5171.

Approach to COVID-19 Similar to Battling Swine Pathogens
One of the most important things to understand is the concept of herd immunity. Individual animals can become immune by recovering from an earlier infection or through vaccination. Some animals cannot become immune due to their age, stress (weaning, environmental conditions), co-infections and for this group herd immunity is a crucial method of protection.
Once a certain threshold of the population is immune, herd immunity gradually eliminates a disease from a population. The term "herd immunity" implies that it must have been developed in livestock but actually it was a term first developed in the 1930s to describe a phenomena observed after a significant number of children had become infected and immune to measles, the number of new infections temporarily decreased, including among susceptible children. It was soon realized...

We will be moved into the new addition of the SD Animal Disease Research & Diagnostic Laboratory (ADRDL) on Monday, December 9th. For dropping off diagnostic samples, please use the west entrance off of Medary (see map above). In addition, there is a night drop off on the west side of the new addition and both an enclosed and open truck area for drop offs and a drive up window for receiving smaller specimens. If you have any questions on the new areas for drop offs, please contact the laboratory at 605/688-5171. Thank you for your support and business!
Dr. Ben Hause Brings His Expertise to SDSU
A veteran of the livestock vaccine and virology world has joined the SDSU Veterinary and Biomedical Science Department and ADRDL as assistant professor and section head for virology. Dr. Ben Hause joined the department in late March, coming from Cambridge Technologies in Worthington, MN.
Dr. Hause's expertise lies in detecting emerging and neglected cattle and swine viruses, working with veterinarians and livestock producers to investigate the impact of these infections on production. Additionally, his research interests will focus on vaccine development for cattle and swine - engineering novel products and engaging with industry partners to bring them to the market.
Prior to his work at Cambridge, Ben held positions at Kansas State University and Newport Labs. A native of Northfield, MN, he completed degrees in chemistry and biology from the University of Minnesota-Morris and the University of Minnesota. Dr. Hause completed his PhD work under Dr. Feng Li at South Dakota State University. Among his many achievements has been an instrumental role in discovering Influenza D virus, and characterizing it in livestock species.
The ADRDL's Bovine Respiratory Disease PCR panels have proven to be popular tools in determining the presence of these pathogens in individuals and herds involved in BRD outbreaks. Veterinarians who are used to interpreting and using results of bacterial culture for these pathogens face some key differences when PCR panel results are used instead...
The outbreak of African Swine Fever in China and other countries has swine producers and veterinarians on edge about the possibility of an incursion into the US swine herd. Since early detection is critical to efforts to contain such a disease, the USDA is partnering with the swine industry, states, and veterinary diagnostic labs on an ASF surveillance effort.
Testing for ASF will focus on high-risk animals, which includes sick pig submissions to veterinary diagnostic laboratories. Diagnostic submissions of pigs with certain clinical or post-mortem signs are eligible; both ASF and Classical Swine Fever tests will be performed at the same time. Negative results will be reported to the submitter, and there is no cost to the client for this test; charges are paid by the USDA.
With the onset of "calf scours season," we asked some questions of Dr. Angela Pillatzki, DVM, MS, DACVP, ADRDL pathologist and section leader for the clinical pathology section; and Julie Colby, principal microbiologist in the section, about one of the lab's more common diagnostic requests: cryptosporidiosis.
Q. What is the preferred sample for cryptosporidiosis detection, and what is the best way to submit the sample to the lab?
A. Fecal material in a sealed plastic bag or plastic container (e.g. pill vial). Whatever container is used should have a good seal so it will not leak during transport. Keeping the sample cool during transport and submitting samples in a timely manner are always good ideas.
Q. Are there any conditions that would make a sample unsuitable for crypto testing?
A. Overall, fecal samples are pretty stable for the crypto testing we perform. Paying attention to...
Prompt and Accurate Veterinary Diagnostic Services
The South Dakota Animal Disease Research and Diagnostic Laboratory (ADRDL) has served the citizens of the state and region with timely and accurate veterinary diagnostic services since 1887. A dedicated and experienced staff performs a full range of diagnostic testing services that arm veterinarians and health officials with the information they need to protect and improve animal and therefore, human health.
The staff of the ADRDL are nationally recognized for their skill in diagnosing key diseases of cattle, pigs, and other livestock. Additionally, the ADRDL supports veterinarians and caretakers of horses and companion animals, plays a vital role in identifying zoonotic diseases such as rabies, and helps to keep our food supply safe by testing food products for bacteria that may cause food-borne illness.
The ADRDL is American Association of Veterinary Laboratory Diagnosticians(AAVLD) accredited. In addition, the lab is an integral member of the USDA National Animal Health Laboratory Network (NAHLN), a network of diagnostic laboratories across the US that help detect nationally significant animal diseases such as influenza and Foot & Mouth Disease. Expertise in detecting agents of food-borne illness is important in the ADRDL's role as a regional laboratory for the Food Emergency Response Network(FERN). Participation by the ADRDL in the FDA Veterinary Laboratory Investigation Response Network (Vet-LIRN) (hotlink this name to the link below… https://www.fda.gov/AnimalVeterinary/ScienceResearch/ucm247334.htm helps to document, investigate, and diagnose animal feed or drug related illnesses. These efforts can contribute to overall food safety as animal feed events could signal potential issues in human food. The ADRDL also contributes to the FDA Genome Trakr.
NOTE: Starting April 1st, as per the AAVLD Accreditation requirements, full diagnostic laboratory reports will be sent labeled as "preliminary", indicating some results are still pending, or "final", where no test results are pending. Previously, for some cases, only the newest results were sent via e-mail or fax.
Thank you for your understanding of this requirement. If you have any questions or comments, please feel free to contact the laboratory.
