CL Davis Diagnostic Exercises

The main goal of these Diagnostic Exercises is to provide interesting cases, focusing on the gross pathological lesions and associated histopathologic or cytologic findings. This material can be of great use for veterinary students, in-training pathologists, and ACVP diplomates alike.

There will be one contribution per month of the year; anyone may contribute. To do so, please contact Dr. Vinicius Carreira at to identify a convenient date for your submission and to receive templates to be used. Spots will be filled out on a first-come first-served basis.

Tissue from a sheep.

Morphologic diagnosis: Multiple esophageal sarcocysts

Cause: Sarcocystic gigantea

Comment: Finally! An appropriately named protozoan.. it IS gigantic! But now some really boring protozoologists want to call it Sarcocystis ovifelis...:(

(I miss the original name, Balbania gigantea..)

New today in Noah from the AFIP Archive.

Material from the stomach of a horse.

Name the agent: Taxus sp.

This was a case of mine from the early 1990's. A draft horse pulling a caisson during a funeral collapsed and died without warning. Autopsy was performed within two hours, and aside from minimal flaccidity of the heart muscle and fluid in the pericardial sac, the cadaver was pristine. This material was removed from the stomach and between the teeth of the horse) and the cause of death was established.

Yew bushes are a very common ornamental shrub in cemeteries, but the leaves of the all Taxus species are extremely toxic (with less than a handful enough to kill a horse). Taxine is a potent inhibitor of calcium channels within the myocardium and also impairs electrical conduction.

While yew does not appear to be very tasty to horses, this horse was likely halted near a bush, and being bored with the proceedings, nibbled enough to result in its own demise. The horse did not receive its own funeral, but the bushes were removed from alongside all of the carriageways to prevent further problems.
