Case report: Peritonitis caused by Pantoea agglomerans from pet dog exposure in peritoneal dialysis.

RATIONALE: Peritonitis caused by Pantoea agglomerans is a rare occurrence in patients undergoing peritoneal dialysis. Cases potentially linked to pet dogs are even rarer, and there is limited literature available.

PATIENT CONCERNS: A patient undergoing peritoneal dialysis presented with symptoms of peritonitis, including abdominal pain and cloudy dialysis fluid.

DIAGNOSES: Microbiological analysis identified P agglomerans as the causative organism.

INTERVENTIONS: The patient was treated with targeted antibiotic therapy and showed a positive response.

OUTCOMES: During a subsequent medical interview, it was revealed that the patient had close contact with their pet dog, raising the possibility that the infection may have been associated with this exposure.

LESSONS: This case highlights the importance of considering zoonotic transmission as a potential source of infection in peritoneal dialysis patients, particularly when there is close contact with pets. Healthcare providers should educate patients about the potential risks posed by pets and implement preventive strategies to mitigate such risks.
