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.

Mystery Crystals in a Kitty
This 1-year-old cat came in lethargic with diarrhea, and the lab results raised eyebrows—Heinz bodies plus strange bow-tie-shaped urine crystals. Still investigating possible exposures and keeping a close eye. Some cases don’t give easy answers! 🐱🔬

Our 5-year-old patient had tummy troubles, a look under the microscope revealed the culprit: Enterococcus faecium bacteria forming tiny chains in the bile. Science to the rescue! 🦠🔬

Did You Know? Greyhounds Have Unique Blood Cells!
Greyhounds and other sighthounds often have grey eosinophils, which look clear under the microscope because their granules don’t stain like usual.
Good news: This is completely normal for these breeds! Just another special trait that makes sighthounds so unique.
