Summary:
The August 2025 edition of the Prairie Diagnostic Perspective reflects both change and continued advancement at Prairie Diagnostic Services (PDS).
Farewell to Leslie Read
After many years of dedicated service, PDS celebrates the retirement of Leslie Read, affectionately known as “the Voice of PDS.” Leslie’s warmth, professionalism, and commitment to client service made her a beloved figure for both clients and staff. PDS extends its gratitude and best wishes as she embarks on her next chapter.
Welcome to Janelle Hren
PDS welcomes Janelle Hren as the new Voice of PDS. Bringing extensive experience in the veterinary services industry and a strong dedication to client care, Janelle is expected to continue the tradition of exceptional service that Leslie helped establish.
Case Feature: Suspected Clitoral Adenocarcinoma in a Dog
Authored by Dr. Lilani Munasinghe and Parneet Jandi, this case describes the cytologic evaluation of a large vaginal mass in a nine-year-old Bullmastiff, diagnosed as a presumptive clitoral adenocarcinoma—a rare neoplasm in dogs. The lesion exhibited epithelial clusters with neuroendocrine-like features, and while metastasis is common in such tumors, no follow-up data were available.
Laboratory and Biosafety Updates
PDS reminds clients of protocols for suspect anthrax submissions, including correct labeling, notification procedures, and adherence to biosafety regulations. The Clinical Pathology Laboratory also clarified that it cannot process Risk Group 3 (RG3) pathogens, such as Blastomyces spp., until negative screening results are confirmed—aligning with practices at other reference labs.
New Diagnostic Tests
A major announcement details a broad expansion of diagnostic capabilities, including new PCR assays and sequencing for avian, porcine, bovine, and environmental pathogens. Newly available tests include:
- Atypical Porcine Pestivirus PCR (APPV)
- Avian Adenovirus Genotyping
- Cache Valley Virus PCR
- Porcine Astrovirus, Sapelovirus, and Teschovirus PCRs as well as NIRS feed analysis and new necropsy service options. Several older ELISA-based respiratory panels and Strychnine testing were discontinued or redirected to external labs.
Guidelines and Best Practices
The issue concludes with a useful clarification on veterinary terminology:
- “Sudden death” describes animals that die unexpectedly and appear healthy prior to death—often requiring urgent investigation for infectious, toxic, or metabolic causes.
- “Found dead” refers to animals discovered deceased with unknown timing or prior illness, where post-mortem analysis provides primary diagnostic insight.
This distinction helps veterinarians communicate clinical context accurately and prioritize appropriate diagnostic approaches.
