Chryseobacterium meningosepticum infection and cardiac tamponade in a long-term hemodialysis patient.

Chryseobacterium meningosepticum is a lactose-nonfermenting gram-negative bacilli ubiquitously found in the natural and hospital environment. Clinical infection caused by C. meningosepticum is very rare among healthy adults. We present the case of a patient with end-stage renal disease who developed purulent pericarditis with C. meningosepticum infection, which rapidly evolved into cardiac tamponade and death. To our knowledge, this is the first case in which C. meningosepticum caused fatal purulent pericarditis in a hemodialysis patient.
