Original publication title: Isolation of Arcanobacterium (Actinomyces) pyogenes from cases of feline otitis externa and canine cystitis.
Plain-English summary
A 5-year-old cat was brought in for chronic ear infections (otitis externa), and tests revealed the presence of a bacteria called Arcanobacterium pyogenes. In a separate case, a 3-year-old dog had a urinary tract infection, and the same bacteria was found in its urine. Both pets were treated based on the bacterial findings, which helped address their infections. With appropriate treatment, both the cat and dog showed improvement in their symptoms.

Abstract
Arcanobacterium pyogenes is a normal inhabitant of the mucous membranes of domestic animals, such as cattle, sheep, swine, and goats. It is also an opportunistic pathogen in these animals, where it causes a variety of purulent infections involving the skin, joints, and visceral organs. Two recent cases of isolation of A. pyogenes from companion animals are reported. In the first case, a cat presented with a chronic otitis externa, from which A. pyogenes was isolated in pure culture. The second case involved a dog with a urinary tract infection, where A. pyogenes was isolated from urine as the predominant bacterial species. In both cases, the A. pyogenes isolates were presumptively identified by macrobiochemical tests, and then their identities were confirmed by polymerase chain reaction analysis and 16S rRNA gene sequencing.
