First case report of Solobacterium moorei bacteremia due to acute cholangitis in South Korea

Solobacterium moorei is an anaerobic gram-positive bacillus that rarely causes bacteremia. Herein, we report a case of S. moorei bacteremia associated with acute cholangitis in a patient without malignancy. The patient had a history of chronic pancreatitis with pancreaticogastrostomy and presented with fever and abdominal pain. Computed tomography scans showed acute cholangitis and S. moorei identified in blood cultures were confirmed by matrix-assisted laser desorption/ionization-time of flight mass spectrometry and 16S rRNA sequencing. The patient was successfully treated with endoscopic retrograde biliary drainage and antibiotics including meropenem and piperacillin-tazobactam.
