Paraneoplastic hypercalcemia in a canine patient with a mandibular salivary carcinoma.

Objective: To describe a novel presentation of paraneoplastic hypercalcemia caused by a canine salivary carcinoma.

Animal: A 6-year-old intact male Husky with hypercalcemia and a spontaneous salivary carcinoma, stage III.

Clinical Presentation, Progression, And Procedures: The dog presented with polyuria, polydipsia, and hypercalcemia.

Isolation of Aureimonas altamirensis, a Brucella canis-like bacterium, from an edematous canine testicle.

Microbiological and histological analysis of a sample from a swollen testicle of a 2-year-old Border Collie dog revealed a mixed infection of the fungus Blastomyces dermatitidis and the Gram-negative bacterium Aureimonas altamirensis. When subjected to an automated microbial identification system, the latter isolate was provisionally identified as Psychrobacter phenylpyruvicus, but the organism shared several biochemical features with Brucella canis and exhibited agglutination, albeit weakly, with anti-B. canis antiserum.
