NVDC diagnosticians contribute to understanding of bovine pinkeye

Matt Hille and Dustin Loy look over a culture of Moraxella bovis in the Veterinary Diagnostic Center lab.

Research notes, reference materials, reports — such are the items to be found in the East Campus office of Dustin Loy, a professor in the University of Nebraska–Lincoln’s School of Veterinary Medicine and Biomedical Sciences. But Loy’s office also features an unusual drawing, a scientific one from deep in the university’s history. Continue reading


Price changes effective July 1, 2023

Dear Nebraska Veterinary Diagnostic Center Clients,

We truly appreciate your diagnostic business and make every effort to provide you with timely, accurate and affordable services. From time to time, as supply and operational costs increase, we are forced to increase what we charge for diagnostic and research services. Over the past two years our costs have increased significantly. As a result, we will be implementing a 10% fee increase for many of our diagnostic tests starting July 1, 2023.

We wanted to provide you with ample notice to adjust your pricing accordingly. If you have any questions or require further information, please reach out and contact us.

Thank you for your continued support and business.

Loy named NVDC director

March 8, 2023—Dr. Dustin Loy has been selected and has accepted the position of director of the Nebraska Veterinary Diagnostic Center, effectively immediately. Loy succeeds Bruce Brodersen, who spent more than 30 years on the UNL faculty and had led the center since 2019.

Dr. Loy grew up on a small beef operation in central Iowa. He received his BS in animal science, DVM in food animal medicine, and PhD in veterinary microbiology from Iowa State University. He is a diplomate of the American College of Veterinary Microbiologists with specialties in bacteriology, virology and immunology.

Prior to coming to the University of Nebraska-Lincoln he worked at a biotech startup developing RNA-based vaccines for animals. Currently he is a professor, veterinary diagnostic microbiologist and faculty supervisor for the bacteriology and molecular diagnostic laboratories in the NVDC. His research focuses on the application of genomics, MALDI-TOF mass spectrometry, infrared spectrometry (FT-IR), and PCR to pathogens, with a focus on bovine diseases and antimicrobial resistance, where he has contributed to more than 50 publications, several books and patents and numerous grants.

Dr. Loy is an instructor in both the veterinary science undergraduate curriculum and the Professional Program in Veterinary Medicine.

Dr. Loy has served in leadership and committee roles through the American Association of Veterinary Laboratory Diagnosticians, the American College of Veterinary Microbiologists, the Nebraska Veterinary Medical Association, and the Lincoln-Lancaster Board of Health.

Congratulations to Dustin, and thanks to the Search Advisory Committee, faculty and staff of the NVDC for their efforts throughout the selection process.

HPAI in cats

February 24, 2023—Although the recent highly pathogenic avian influenza virus, H5N1, affects mainly birds, it been reported to infect a variety mammal species. Recently, we have encountered cases of domestic cats becoming infected. The case report linked below describes the findings from two domestic cats that were infected with the virus.

Fee to cover 'Stat' testing

November 2, 2022—The Nebraska Veterinary Diagnostic Center will begin charging an additional $25 fee for cases in which “Stat” testing is requested. We are doing this as a method to recoup expenses incurred when specific testing is requested outside of our normal testing schedule. These expenses are due to extra time, reagents, and labware needed to perform tests outside of our normal workflow. Please plan ahead to allow plenty of time for testing when scheduling sample collections.

Update on avian influenza

March 17, 2022—The first case of avian influenza in Nebraska was identified in Lancaster County on March 4, 2022, in a wild goose. It has now been identified in nearly all corners of the state and is spreading. We have seen cases involving domestic poultry as well as wild waterfowl. To date, there have been no cases in commercial production facilities.

The strain that we are seeing has been identified as the Eurasian lineage goose/Guangdong H5 clade There have been no reports of human infection. Reported clinical signs in chickens include sudden reduction in water consumption, reduced egg production, diarrhea, respiratory distress, and sudden and significant increase in mortality. We have also been told of CNS signs in wild waterfowl. Mortality rates can be as high as 100% in chickens. If you are observing these signs in your birds, you should contact the State Veterinarian’s office at 402-471-2351 or the USDA at 866-536-7593. If you see wild birds with suspicious signs, contact your local Nebraska Game and Parks Commission Conservation Officer

The Nebraska Veterinary Diagnostic Center (NVDC) is a Level 1 laboratory in the National Animal Health Laboratory Network (NAHLN) and has been activated to respond to this outbreak. When there is a suspected case, samples are tested here at the NVDC for rapid turnaround. Non-negative test results reported at the NVDC are actionable as deemed by the NAHLN, and samples are sent to the National Veterinary Services Laboratory in Ames, IA, for follow-up confirmation and characterization of the isolate.

If you have further questions, call the numbers above or contact the NVDC at 402-472-1434.

EZ-Ship program available now

February 11, 2022—The EZ-Ship program is available again. For details on using EZ-Ship, please visit the Shipping page of our website. Thank you for your patience as we resolved the issues.

Accession and histology fees to increase Feb. 1, 2022

Beginning Feb. 1, 2022, the NVDC tests catalog will reflect new prices for some items in our fee schedule. These prices apply to samples received on or after that date.

As always, we make every effort to keep fees low for our clients; however, over time modest increases are necessary. This is the first time in many years these fees have been adjusted.

We appreciate you and your business. If you have any questions, please don't hesitate to contact us.

Reduced disposal fee for cattle and pigs

November 11, 2021—Last year, we were notified by the rendering company that picked up our cattle and pigs that they would no longer service the NVDC. Because of that, we had to raise our disposal fee to a level that was prohibitive for you to bring carcasses to us. After working with the renderer, I’m happy to say they have agreed to once again to pick up carcasses. The disposal fee for cattle and pigs will revert back to what it was previously.

The past increase in fees seriously reduced our caseload for necropsies. Part of our mission is disease surveillance and discovery of emerging diseases. Without us performing these postmortem exams we are not fulfilling our mission. I hope this update about fees will help you convince your clients to take advantage of our services.
