Protothecosis in a dog

A case of a disseminated algal infection is reported in a young rough-coated collie dog with progressive neurologic deficits, blindness, and hemorrhagic diarrhea. Prototheca zopfii organisms were cultured from feces, urine, and blood. At necropsy, granulomas containing typical organisms were identified within the proximal colon, heart, kidneys, and eyes.     

Hypocalcemia in a dog

A case of hypocalcemia was presented with a concurrent hyperphosphatemia. Normal renal function tests excluded primary renal insufficiency. The diet was thought to contain a normal ratio of calcium and phosphorus and, therefore, nutritional secondary hyperparathyroidism was not considered. The radiographs showed normal bone density and the dog was not lame. Concentrations of immunoreactive parathyroid hormone were measured in an attempt to classify the etiology. The dog was successfully managed with calcium supplementation and vitamin D(3) or oral calcium alone.
