First Case of Pseudoclavibacter alba Bacteremia in a Patient with Cholangitis

Background: Pseudoclavibacter alba isolated from human urine in culture collection was introduced as a new species, but since then, no other reports on P. alba isolated from the environment or organisms have been published. We thus present the first case report of P. alba bacteremia.Methods: An 85-year-old female patient was admitted with intermittent abdominal pain and chills that had persisted for one week. She was diagnosed cholangitis with common bile duct stones.Results: Gram-positive bacteria were detected in her peripheral blood culture and identified Pseudoclavibacter species by matrix-assisted laser desorption-ionization-time of flight mass spectrometry. Pseudoclavibacter alba was identified by performing the 16S ribosomal RNA gene sequence.Conclusions: This is the first case report of P. alba bacteremia in a patient with cholangitis.
