Plain-English summary
A 10-year-old diabetic dog was brought in with a urinary tract infection caused by a rare strain of Listeria monocytogenes, which is usually linked to foodborne illness in humans. The dog was treated with cephalexin, an antibiotic, for four weeks. Thankfully, the dog fully recovered after the treatment.

Abstract
Listeria monocytogenes, a well-described cause of encephalitis and abortion in ruminants and of food-borne illness in humans, is rarely associated with disease in companion animals. A case of urinary tract infection associated with an atypical, weakly hemolytic L. monocytogenes strain is described in a diabetic dog. The serotype of the L. monocytogenes isolate was determined to be 1/2a (3a), with the multilocus genotyping pattern 2.72_1/2a. A nucleotide substitution (Gly145Asp) was detected at residue 145 in the promoter prfA region. This residue is within the critical helix-turn-helix motif of PrfA. The source of the L. monocytogenes strain remains unknown, and the dog recovered after a 4-week course of cephalexin (30 mg/kg orally twice daily).
