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 spe-cies, 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 per-sisted 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.
