Executive Directors Message | |
|
Greetings, veterinary diagnosticians! I hope that 2025 has been treating you well so far. I know you are all busy at this time of year, the winter season traditionally being the peak of many morbidity and mortality investigations. The laboratory results you are diligently producing every day provide veterinarians, food animal producers, pet owners, wildlife managers, and state/federal animal health officials with the precise diagnostic data they need to keep our animal populations healthy. Your work has an impact on human health as well since humans are just one of many animal species that share microbes with the rest. Your work with food animals is directly related to food security… You are part of the national and international effort to feed the world healthy, wholesome food and animal-derived protein. I truly hope you feel a pride in being a part of this meaningful work, and I hope you feel appreciated. Thank you for your hard efforts.
The National Animal Health Laboratory Network (NAHLN) has been very busy battling the highly pathogenic avian influenza (HPAI) virus in poultry and dairy cattle. The NAHLN is an effective state/federal partnership, and AAVLD is proud to represent the accredited state laboratories in this effort. HPAI has been a frustrating problem since 2022, but once again, a major disease outbreak has demonstrated the importance and absolute necessity of working together through the NAHLN. Thank you, leaders and veterinary diagnosticians, for your great ongoing efforts to control this disease.
Since the last newsletter, we have a new President and a new Secretary of Agriculture. Your AAVLD leaders have already been working with Washington leaders to inform them of the complex work that you do, the importance of the State/Federal partnership, and the NAHLN. I believe President Trump and Secretary Rollins will readily recognize the role our labs play relative to national food security and public health. Next month, AAVLD and USAHA leaders will meet in DC with key agency leaders to discuss the ongoing coordination of the battle to maintain healthy animal and human populations.
Sincerely,
David H. Zeman, DVM PhD, DACVP
AAVLD Executive Director

US House Leaders Tour ISU VDL | |
|
The Chair of the US House Agriculture Committee, the Honorable G.T. Thompson, and Representative Randy Feenstra recently toured the new Iowa State University Veterinary Diagnostic Laboratory. Hosted by Executive Director Pat Halbur, Director Rodger Main, and CVM Dean Dan Grooms of ISU.
The House leaders were impressed and in a follow up story in the Des Moines Register expressed their support for the mission of the ISU VDL: “In the farm bill we passed out of the Agriculture Committee with bipartisan support last May, we acknowledged the importance of foreign animal disease prevention and response by fully funding the three-legged stool: the laboratory network, the National Animal Disease Preparedness and Response Program, and the National Animal Vaccine and Veterinary Countermeasures Bank. The three-legged stool of animal health supports on-farm biosecurity efforts, vaccine stockpiles, diagnostic test kits, emergency response, and farm education initiatives on foreign animal disease prevention and mitigation. Coordination among local, state and federal partners; farmers and ranchers; our university systems; and other pertinent stakeholders is vital to keeping animal diseases out of our country and responding to emergencies in an effective and efficient manner.” Full article here:

Dr. Jianqiang Zhang, professor of veterinary diagnostic and production animal medicine, has been named the Lora and Russ Talbot Endowed Professor in Veterinary Medicine.
The endowed faculty position is one of three named professorships that the Talbots have established in the College of Veterinary Medicine. Dr. Rachel Allbaugh, professor of veterinary clinical sciences, and Dr. Heather Greenlee, professor of biomedical sciences, are the other two Talbot Endowed Professors.
A faculty member in the College of Veterinary Medicine since 2012, Zhang earned his PhD in molecular virology from the University of Kentucky. He also received a MD degree from the Beijing Medical University School of Public Health.
Zhang is internationally renowned for his role in building Iowa State’s Veterinary Diagnostic Laboratory’s virology and molecular diagnostic services unit for food animal diseases into what many consider to be the best in the world. He has an exemplary record of presentation and publication of his work through scientific abstracts and proceedings papers and national and international meetings and in high-quality peer-reviewed journals.
Because of his productivity and reputation in diagnostic medicine and infectious disease research, Zhang has been invited to serve on the organizing committees of several major national and international scientific meetings.
His research interests include the development and validation of diagnostic assays for viruses of veterinary significance; genetic classification, pathogenicity, and cross protection of PRRSV; molecular epidemiology, pathogenicity, immune responses, and vaccine development of swine enteric coronaviruses; as well as the characterization of other viruses, such as porcine sapovirus, porcine rotaviruses, and avian metapneumovirus.

Bacillary hemoglobinuria in beef cattle infected with Fascioloides magna in Missouri, Ierardi et al.
Abstract. Bacillary hemoglobinuria (BH) is an infectious disease, mostly affecting cattle, caused by Clostridium haemolyticum (C. novyi type D), with acute hepatic necrosis and intravascular hemolysis. Cattle are typically predisposed to BH by liver injury caused by Fasciola hepatica, although cases have been reported in cattle without evidence of this parasite. Here we describe a cluster of 14 BH cases from 7 counties in north-central to central Missouri submitted to a veterinary diagnostic laboratory between December 2020 and April 2023. Postmortem examination in all cases revealed hemoglobinuria and acute hepatic necrosis with large numbers of gram-positive bacilli with terminal-to-subterminal spores. Flukes, fluke ova, and/or fluke pigment consistent with Fascioloides magna were identified in 12 of 14 cases. Sequences of the nuclear ribosomal internal transcribed spacer 1 (ITS1) from one fluke had 100% identity to F. magna. More

JVDI call for submissions for “Special issue on racehorse diseases, injuries, welfare, and safety” | |
|
Racehorse welfare and safety is a vital component of the racing industry, with ever-increasing scrutiny and expectations from both the general public and the racing community. Since 2009, catastrophic musculoskeletal injuries sustained during Thoroughbred racing have decreased by over 40%, with continued room for improvement. The postmortem examination provides invaluable information not only in cases of catastrophic musculoskeletal injury but also in the event of exercise-associated sudden death or deaths due to medical causes.
We are inviting submissions to a JVDI special issue on racehorse diseases, injuries, welfare, and safety to be guest edited by Dr. Laura Kennedy, University of Kentucky; Dr. Francisco Uzal, University of California–Davis; Dr. Julie Engiles, University of Pennsylvania; and Dr. Sue Stover, University of California–Davis.
If you are interested, please submit an abstract of up to 250 words describing your proposed topic by March 31, 2025. Full research papers, case series, brief reports, and reviews of a focused topic will be considered, as will single-animal case reports if they are novel and include a review of the literature on the focused topic of the report. For abstracts on topics considered suitable for the special issue, authors will be notified by April 15, 2025, and full submissions will be expected by September 1, 2025. Submitted manuscripts will proceed through the usual JVDI peer-review and editorial process, with publication expected in the winter of 2025–2026. Page charges of $75/printed page will apply—there is no color page charge for online-only publications.
Please submit your abstract to guest editor Dr. Laura Kennedy, drlaurakennedy@uky.edu
