Plain-English summary
A 2-year-old Border Collie was brought in with a swollen testicle, which was found to have a mixed infection involving a fungus and a rare bacterium called Aureimonas altamirensis. The infection was confirmed through advanced genetic testing, as initial identification methods were inconclusive. While the exact impact of this bacterium on the dog's health is unclear, the case emphasizes the need for precise identification of microbes in veterinary medicine. Treatment details were not specified, but addressing the mixed infection would be crucial for the dog's recovery.

Abstract
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. Unequivocal identification of the organism was only achieved by 16S ribosomal RNA gene sequencing, ultimately establishing the identity as A. altamirensis. Since its first description in 2006, this organism has been isolated infrequently from human clinical samples, but, to the authors' knowledge, has not been reported from a veterinary clinical sample. While of unknown clinical significance with respect to the pathology observed for the polymicrobial infection described herein, it highlights the critical importance to unambiguously identify the microbe for diagnostic, epidemiological, infection control, and public health purposes.
