First case of post-endoscopic retrograde cholangiopancreatography bacteraemia caused by Acinetobacter ursingii in a patient with choledocholithiasis and cholangitis.

We describe what we believe to be the first case of biliary sepsis caused by Acinetobacter ursingii. The patient was a healthy woman with no comorbidities who presented with choledocholithiasis and cholangitis. The performance of an endoscopic cholangiopancreatography was the trigger for A. ursingii bacteraemia. This report highlights the inadequacies of conventional phenotypic tests usually available in clinical microbiology laboratories for the identification of Acinetobacter species.
