Laboratory Diagnosticians' News Matters
AAVLD Executive Director's Message
David Henry Zeman, DVM, PhD, DACVP
2022 Hybrid Annual Meeting On Track
Submit Abstracts Now!!
Greetings fellow veterinary diagnosticians! I hope all is going well and that you are enjoying the fresh air of spring. We were excited to launch our call for abstracts on April 1st for the 2022 annual meeting in Minneapolis. Last year we had over 170 scientific presentations and several symposia for our attendees. This will be our second year of offering both live on-site attendance as well as virtual on-demand attendance.  We have discovered that our membership appreciates both options. We understand that someone must stay home and take care of the laboratory, however, now those staying at home can still participate in a great continuing education experience from the convenience of their laptop. On-site attendees can also view recordings of every scientific presentation at their convenience during the meeting or after they come home. No longer do attendees have to make tough decisions about which presentation they have to attend if they are occurring concurrently. 

So, if you are a mentor or advising professor of a diagnostician trainee, please work with them and encourage a scientific submission for a live presentation, recorded presentation or poster. Also encourage them to apply for various trainee awards including travel awards, and outstanding presentation awards. They are all listed in pertinent documents on our annual meeting website page; applicants apply as they submit their abstracts through our ScholarOne system.

If you are a Committee Chair, spring and summer are great times to meet with your committees and discuss issues for your discipline and prepare for final deliberation and action at the annual meeting. 

Lastly, we are very proud of the response put forth by many of our AAVLD laboratories relative to the avian influenza outbreak occurring across the country. It has been a challenging time for the poultry industry, but I hear much appreciation regarding the laboratory response to testing needs, which continues as farms recover and begin restocking their barns.  The NAHLN partnership between state and federal laboratories has once again proven to be a vital infrastructure for food producers and consumers. Thank you all for your dedicated efforts!

Most sincerely,

David H. Zeman, DVM, PhD, DACVP

Executive Director, AAVLD
Call for Abstracts and Award Applications:
65th Annual AAVLD Meeting
October 6-12, 2022, Minneapolis, Minnesota
Submission opened April 1st & closes May 31st
It is with hard to believe the annual meeting is just a little more than 6 months away. It was great to see many of you in-person in Denver last year and we are planning a similar hybrid format for the annual meeting this year in Minneapolis. All presenters, whether planning to attend in-person or remotely, will submit an electronic recording of their presentation that can be viewed by remote participants. As an added value, these presentations will be available for viewing on-demand by all meeting attendees until December 1st so there is no need to worry if you want to see two presentations that are scheduled at the same time.

The theme for the plenary session is “Technological Advances in Veterinary Diagnostics: What’s Here and What’s on the Horizon?” This session will include talks by experienced scientists in the fields of digital pathology, microbiology, toxicology, and bioinformatics. Please watch for more information on our plenary speakers and meeting details in upcoming newsletters and on our meeting website at aavld.org. 

We count on you to further enrich the scientific program through the submission of your abstracts on cutting-edge diagnostic science. According to meeting feedback surveys, the quality of presentations in the Scientific Oral and Poster Sessions is the single most important reason for attending the AAVLD Annual Meeting. There are few other venues where veterinary laboratory scientists can present and share information across so many disciplines and learn from experts in other peer laboratories. Now is the time to start preparing your abstracts as the submission portal opened on April 1st.

Please visit the meeting website at aavld.org and review the many travel and presentation awards that you, your students, or staff may wish to apply for. If applicable, please also consider submitting a manuscript or brief communication based upon your oral or poster presentation to the Journal of Veterinary Diagnostic Investigation (JVDI), the official journal of the AAVLD.

For decades veterinarians have had an arsenal of safe and effective drugs for which to rely upon to manage common parasites in pets and agricultural animals.

But over the years, many parasitic species have developed varying levels of resistance to many of those drugs, creating challenges for veterinarians, including those like Dr. Laura Williams who has dedicated her career to the field of parasitology.

Williams, a licensed veterinarian at the Washington Animal Disease Diagnostic Laboratory at Washington State University, is one of fewer than 50 veterinarians in the United States board certified in parasitology by the American College of Veterinary Microbiologists (ACVM) and the only one in Washington. At WADDL, she serves as section head of the parasitology laboratory, a full-service diagnostic laboratory offering testing for the detection of parasitic infections in domestic and wild animals. Williams consults with the public, producers, and veterinarians in the identification, treatment, and control of parasites.
“The concern in parasitology is the resistance to medications – there are only a limited number of antiparasitics that we have available on the market,” Williams said. “I can’t speak about what is going to be available in the future, but it has been about 30 years since big classes have been released into the market, so there’s a lot of concern about once resistance develops in parasites like hookworms in dogs and cats or strongyles in horses and cattle, what do we do then? That’s why we have to figure it out before we get there.”

With resistance a growing concern, Williams is encouraging more sustainable solutions to parasite control and management, which means moving away from drugs as the sole management strategy. For large animal producers, many of these methods revolve around stocking density and maintaining a clean environment for livestock.

“Stocking density is by far the biggest contributor to too many parasites in animals,” she said. “Having too many animals in the same pasture just perpetuates the lifecycles of these parasites, and the animals can get overrun pretty easily. If you can spread out animals more and you can clean up poop from the pasture, that is probably going to make the biggest difference in controlling parasites.”

In addition to assisting with management practices and parasite control, Williams is also an expert at identifying parasites. 

“As a pathologist and diagnostician, my job is to diagnose disease in animals. That interest extends to the identification of parasites too, whether they are sent to us from a live animal or we find them on a post-mortem exam,” Williams said. “It is nice that WADDL has the tools I need to be able to do that identification and ultimately help people control these issues in their animals.”

Williams earned a Doctor of Veterinary Medicine from WSU in 2013 and stayed at the university for a combined pathology residency and doctoral program, which she completed in 2018. She became board certified in pathology in 2019.

After earning her doctorate, she remained at WSU as clinical instructor, teaching a parasitology course to veterinary students. The course fueled her interest in the field and she took a more active role in the parasitology section at WADDL. In September of 2021, she became ACVM board certified in parasitology.

The Arizona Veterinary Diagnostic Laboratory (AZVDL) is proud to announce
Dr. Yan Zhang as the new Director beginning May 16!
Dr. Zhang comes to Arizona after 24 years of diagnostic laboratory work including, since 2002, the Veterinary Virologist/Section Head of Virology, Avian Serology, and Molecular Diagnostics, Next Generation Sequencing, Animal Disease Diagnostic Laboratory, Ohio Department of Agriculture, Reynoldsburg, Ohio.

JVDI goes green: online-only publication for AAVLD members as of January 2022
Grant Maxie, DVM, PhD, DACVP
  •  As of our January 2022 issue, JVDI joins the evolution of scholarly journal publishing by going online-only for AAVLD members – for full details, see our November 2021 editorial.

  • 84% of respondents to our 2021-member communications survey were in favor of online-only publication of the Journal.

  • Environmental benefits include: no consumption of ink and paper; no mailing wrappers (which resolves the issue of plastic versus paper); no mail deliveries; and no waste, recyclable or not, generated.

  • These changes will also lead to some cost savings for AAVLD, allowing us to keep membership dues as low as possible.

  • The transition to electronic publishing is happening worldwide and fits with the rest of our fully electronic publication process—from submission, through reviewing, revising, editing, proofing, and compiling.

  • The AAVLD office will send members an email notification of the Table of Contents of each bi-monthly issue of JVDI. Full articles are embargoed and accessible only to subscribers (including AAVLD members and libraries) for 12 mo following publication; members will sign-in to the AAVLD website to access full articles.

  • Effective November 2021, a full-issue, cover-to-cover PDF of the Journal will be available to all subscribers. As with a magazine or newspaper, the PDF can be scrolled through, or a topic selected and found by a word search.

JVDI in Focus
JVDI in Focus
Our May focus is an article in JVDI’s May issue, in the Special Section on equine gastrointestinal diseases in horses: “Gastrointestinal biopsy in the horse: overview of collection, interpretation, and applications” by Jesse M. Hostetter, Francisco A. Uzal.
Abstract. Evaluation of gastrointestinal (GI) biopsies is a multistep process that includes reviewing an appropriate history, determining sample quality, and evaluating histologic sections. Selected diagnostic parameters that, in combination with intestinal histopathology, can be useful to localize disease to the intestinal tract in the horse include hypoproteinemia and hypoalbuminemia, ultrasound evidence of increased thickness of the small intestinal wall, and alterations in glucose or D-xylose absorption tests. Biopsies may be acquired either endoscopically, or via laparoscopy or standing flank incisional approaches. GI sections should be evaluated using a systematic approach that includes both architectural changes and inflammatory cell infiltrates. Although strategies have been developed for assessment of GI biopsies from the dog and cat, a standardized approach to interpretation of the equine GI biopsy has yet to be developed. GI biopsies pose several challenges to the pathologist, especially for endoscopic biopsies in which the quality of the specimen and its orientation may vary greatly. Architectural changes are arguably the most critical changes to evaluate. In a horse with chronic GI inflammation, such as occurs in idiopathic inflammatory bowel disease (IBD), the cell types encountered frequently are macrophages, eosinophils, lymphocytes, and plasma cells. Increased numbers of these cell types are categorized loosely as mild, moderate, and severe. Specific forms of idiopathic IBD have been further classified by this infiltrate as granulomatous enteritis, eosinophilic enteritis, and lymphoplasmacytic enteritis; there is limited information on microscopic changes with each. Unfortunately, microscopic GI lesions are usually nonspecific, and determination of etiology requires further investigation.
Figures 1–6. Equine gastrointestinal biopsies. Figure 1. Gastric endoscopic biopsy showing only mucosa sectioned tangentially. H&E. Figure 2. Colon surgical biopsy, including full thickness of the colonic wall. H&E. Figure 3. Duodenal surgical biopsy. This biopsy is mostly free of artifact and well oriented, so that numerous villus-crypt units with associated lamina propria can be evaluated. H&E. Figure 4. Gastric endoscopic biopsy that includes only the superficial aspect of the mucosa with artifactually detached mucosal epithelium. H&E. Figure 5. Duodenal endoscopic biopsy with severe crushing artifact. H&E. Figure 6. Duodenal biopsy with muscularis and serosa, but missing mucosa and submucosa. H&E.
