We presented at the Canada West Swine Health Intelligence Network (CWSHIN) Knowledge Exchange Meeting on several less common swine viruses, including Porcine Astrovirus 3, Porcine Astrovirus 4, Porcine Parainfluenza Virus, Atypical Porcine Pestivirus, Porcine Sapelovirus, and Porcine Teschovirus. The presentation reviewed their clinical presentations, pathology, pathogenesis, and diagnostic approaches. PCR assays for these viruses are available at PDS.

Sickle Cells… in a Deer?

We spotted red blood cells in a deer that looked like sickle cells under the microscope.

Is it disease? Normal for the species/breed? Or just an artifact?

Blood smears can surprise you — but don’t worry, we’ve got you covered!

We attended the Beef and Forage Forum, where we presented a couple of research ideas to Saskatchewan beef producers and members of the research community. Diagnostic research is one of our mandates, and innovation is one of our core values. 🐮

A powerful example of BovReproSeq, a PDS-designed sequencing panel that detects 17 common pathogens associated with bovine reproductive failure (and more):

A cow herd was experiencing a high number of open cows and abortions. The producer was unable to collect fetuses or placentas, and the only available specimen was vaginal discharge. The veterinarian was uncertain which tests to request. We recommended BovReproSeq, which detected a significant amount of Campylobacter fetus venerealis (Cfv)—a clinically important finding.

Without BovReproSeq, detection of Cfv would likely have been missed or significantly delayed.

Ever wonder what our Histology lab does to have a little fun and brighten their days?😁🔬

A pronghorn with cavitary lesions within the lung lobes containing myriads of fungal hyphae. The fungal morphology is consistent with Aspergillus spp., characterized by parallel-walled, septate hyphae with dichotomous branching. This lesion resembles pulmonary aspergilloma, in which fungal colonies proliferate within pulmonary cavities with minimal tissue invasion. The cavitary spaces likely represent sequelae of chronic bronchitis with bronchiectasis, chronic abscessation, or remote pulmonary infarction. The intrabronchial pigment is most consistent with hemorrhage secondary to fungal infection.

Liver from a 1-week-old foal.
A routine H&E stain (purple/pink image); eagle-eyed viewers may already spot the cause of this foal’s rapid decline and death. Hepatocytes bordering areas of necrosis contain numerous thin, intracellular organisms arranged in characteristic “haystacks.” Often, as in this case, a silver stain (Warthin-Faulkner) is required to fully appreciate the abundance of organisms present (orange/brown image).

When Cells Invite Guests: Uncommon Urinary Finding

Spotted in a recent dog urine sample; intact neutrophils sitting inside epithelial cells, a phenomenon called emperipolesis.

First described nearly a century ago, emperipolesis occurs when one cell enters another, wanders around, and may leave without causing damage. Fascinating? Absolutely.

Just another reminder that every slide has a story if we take the time to look closely.

The results of the BovReproSeq study were presented at the annual conference of the Western Canadian Association of Bovine Practitioners.

In this study, the diagnostic success rate in abortion cases was 77% when a complete diagnostic package was used, including necropsy, histopathology, BovReproSeq, bacterial culture, mineral panel, and vitamin testing.

We greatly appreciate the funding from Saskatchewan Ministry of Agriculture, Beef Cattle Research Council and Saskatchewan Cattlemen's Association.
