The Purdue Veterinary Medicine community is saddened to learn that a distinguished alumna, Dr. Mary Anna Thrall, of Barnesville, Colorado, passed away Sunday, July 14, 2024. She was 80 years old.

Born in Montreal, Canada, Dr. Thrall was raised in Patoka, Indiana, and knew as early as age six that she wanted to be a veterinarian. She obtained her undergraduate degree from the University of Evansville and then enrolled in the Purdue University College of Veterinary Medicine where she earned her DVM degree in 1970.

Dr. Thrall served as a small animal practitioner for four years before completing a residency in clinical pathology at Colorado State University. She then joined the Department of Pathology faculty in the CSU College of Veterinary Medicine and Biomedical Sciences and served there for 32 years, helping to train more than 40 veterinary clinical pathologists.

Then, in 2010, Dr. Thrall accepted a full-time position as professor of veterinary clinical pathology at the Ross University School of Veterinary Medicine on St. Kitts and continued actively teaching until just a few weeks ago. She also served as head of the Department of Biomedical Sciences at Ross University for three years. She is remembered for her passion for teaching and the way she cared for her students.

During her long career, Dr. Thrall also was involved in continuing education for veterinarians and pathologists and provided more than 300 scientific presentations and continuing education programs. She authored or co-authored numerous scientific publications, abstracts, proceedings, and book chapters, and was the primary author of the clinical pathology textbook, “Veterinary Hematology and Clinical Chemistry.”

A diplomate of the American College of Veterinary Pathologists (ACVP) in Clinical Pathology, Dr. Thrall served as president of both the ACVP and the American Society for Veterinary Clinical Pathology (ASVCP). In 2008, she received the ASVCP Lifetime Achievement Award. Dr. Thrall also was presented with the National Pfizer (Zoetis) AAVMC Distinguished Teaching Award in 2013, and in 2005 was honored as a Purdue University College of Veterinary Medicine Distinguished Alumna. Additionally she was a recipient of the Association for Women Veterinarians Distinguished Service Award and was named a “Pillar of Pathology” by the ACVP.

At one point, Dr. Thall married a fellow Purdue Veterinary Medicine graduate, Dr. Donald Thrall, who was a year ahead of her in veterinary school and earned his DVM degree in 1969. Though they divorced in the 70s, they rekindled their love over the past few years, and Dr. Donald Thrall was there for her until the very end.

Dr. Mary Anna Thrall also enjoyed the companionship of multiple pets, including four dogs and two cats. Her favorite activity was gardening and she maintained two beautiful gardens – one in Barnesville, and the other in St Kitts.

A private burial and Celebration of Life in Barnesville is planned August 3. Dr. Thrall will be remembered as a wonderful mother and teacher who taught people to be the best version of themselves, to think critically, to have fun, and to not be held back by anything or anyone who gets in the way of their dreams and goals.

Beautiful Spring Lilies Pose Serious Danger to Cats

Spring weather heralds the arrival of the beautiful blooms of true lilies (Lilium sp.) and daylilies (Hemerocallis sp.). Unfortunately, many cats have been poisoned by these lovely plants. The poisoning is so severe and the possible consequences so dire (even death) that in 2021, the FDA issued this warning: “Lilies in the “true lily” and “daylily” families are very dangerous for cats. The entire lily plant is toxic: the stem, leaves, flowers, pollen, and even the water in a vase. Eating just a small amount of a leaf or flower petal, licking a few pollen grains off its fur while grooming, or drinking the water from the vase can cause your cat to develop fatal kidney failure in less than 3 days. The toxin, which only affects cats, has not been identified. Dogs that eat lilies may have minor stomach upset but they don’t develop kidney failure.”

Through study abroad opportunities, Purdue’s Veterinary Technology Distance Learning program is helping students think globally

Promoting animal health is a value that transcends cultures and unites the world. That’s why there are veterinary professionals practicing in nearly every country around the globe. But access to high-quality, affordable veterinary care is far from universal — in many nations, particularly developing nations, access to veterinarians is inconsistent, and affordability is a concern all over the world. To confidently address these issues, veterinary professionals must be able to think globally. That’s why Purdue Veterinary Medicine encourages students to study abroad, including those in the Veterinary Technology Distance Learning Program (VTDL). “Study abroad enriches our online curriculum by bringing classroom concepts to life in a global, real-world context,” said Addison Sheldon, the college’s director of global engagement. The VTDL program offers students the option to study abroad in Guatemala, Japan and Zimbabwe by partnering with local universities and organizations.

Ruby’s Road to Recovery

When Ruby first came to the Purdue University Veterinary Hospital, she was just nine months old, and her injuries were more complex than when they first appeared. Ruby is a toy poodle and over a month earlier, while playing, she jumped off a couch and fractured both of her front legs. Despite several weeks of treatment with splints and casts, her legs were not healing properly. She had surgery performed on both her front legs and received a bone graft to help speed up the healing process. With meticulous surgical aftercare and a planned series of rechecks, Ruby began her journey to recovery.
