Zoonotic disease experts and food animal producers who welcome the public to view their animals learned from each other at the most recent "South Dakota One Health" seminar, held June 21 at the USD Health Science Center in Sioux Falls. Public animal exhibits provide excellent learning opportunities for children and others to learn about animal agriculture, but also have been associated with severe illnesses such as E. coli O157:H7 and cryptosporidiosis that can be passed from healthy-appearing animals to people.
For their final course project, students in the Veterinary and Biomedical Sciences Department's VET 403 course, titled Animal Diseases and their Control, have the somewhat daunting task of examining a local livestock operation's animal disease prevention practices.
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).

Viral diseases are always at the top of the list of important diseases affecting livestock, wildlife, and companion animal species. A talented and experienced group of virologists at SDSU’s Animal Disease Research and Diagnostic Laboratory supports daily diagnostic investigations for a wide range of viral diseases.

Clinical problems due to Senecavirus A (SVA), formerly known as Seneca Valley Virus, have quickly expanded from sporadic oddities in far-flung groups of pigs to well-established infections throughout the pig-producing world. The virus is implicated in outbreaks of vesicular (blister-like) sores on snouts and feet of growing pigs, as well as increased mortality in baby pigs.
A large crowd was on hand Thursday, August 31, to celebrate the groundbreaking for the new South Dakota Animal Disease Research building project. The ceremony took place in front of the current ADRDL building and featured South Dakota Governor Dennis Daugaard, SDSU President Barry Dunn, South Dakota State Veterinarian Dustin Oedekoven, and ADRDL Director Jane Christopher-Hennings as speakers.
Tularemia cases affecting animals as well as people arise every year in South Dakota. At the SDSU ADRDL, from 2010 to date (see chart), the disease has been diagnosed in animals 16 times: in 14 cats, one wild rabbit, and one wild prairie dog. These animal cases have come from all corners of the state. While tularemia is often thought of as a spring and summer disease due to the involvement of ticks in its transmission, animal cases have been diagnosed in October, November, and December.
The two (to date) 2017 cases include:
