Pasteurella multocida peritonitis in peritoneal dialysis

Area of Science:

• Infectious Diseases
• Nephrology
• Microbiology

Background:

• Peritonitis is a serious complication for patients undergoing peritoneal dialysis.
• Pasteurella multocida is an opportunistic pathogen typically associated with animal bites or scratches.

Observation:

• This report details six cases of peritonitis caused by Pasteurella multocida in continuous peritoneal dialysis patients.
• A common factor in all cases was close contact with household cats.
• Direct trauma to the dialysis tubing was frequently observed in conjunction with cat exposure.

Findings:

• Pasteurella multocida peritonitis in this context exhibits a rapid onset, with significant bacterial growth occurring within 24 hours of suspected contamination.
• The organism's presence in the peritoneal cavity suggests a route of infection facilitated by breaches in dialysis equipment integrity, potentially introduced via the percutaneous route.

Implications:

• Highlights the importance of considering Pasteurella multocida in peritonitis cases among peritoneal dialysis patients, especially with a history of cat exposure.
• Emphasizes the need for vigilance regarding potential contamination routes, including trauma to dialysis tubing, to prevent rapid-onset infections.
• Suggests enhanced patient education on zoonotic risks and meticulous catheter site care is crucial for preventing such infections.
