Cardiac Tamponade Caused by Campylobacter ureolyticus Purulent Effusion.

A male in his 60s presented to the emergency department with a seven-day history of progressively worsening malaise, dyspnea, nausea, and vomiting. The patient quickly developed septic and obstructive shock, with the ensuing investigation significant for a purulent pericardial effusion causing cardiac tamponade. Subsequent cultures grew Campylobacter ureolyticus, which is commonly associated with the gastrointestinal tract and is one of many microorganisms that cause diarrhea. Yet, studies have identified this pathogenic organism in oral infections, infectious meningitis, and soft tissue infections, but not pericardial effusions. This organism is an emerging pathogen and warrants renewed research efforts.
